Eudaimonia

From Wikipedia, the free encyclopedia

Eudaimonia (Greek: εὐδαιμονία [eu̯dai̯moníaː]), sometimes anglicized as eudaemonia or eudemonia /jdɪˈmniə/, is a Greek word commonly translated as happiness or welfare; however, "human flourishing or prosperity" has been proposed as a more accurate translation. Etymologically, it consists of the words "eu" ("good") and "daimōn" ("spirit"). It is a central concept in Aristotelian ethics and political philosophy, along with the terms "aretē", most often translated as "virtue" or "excellence", and "phronesis", often translated as "practical or ethical wisdom". In Aristotle's works, eudaimonia (based on older Greek tradition) was used as the term for the highest human good, and so it is the aim of practical philosophy, including ethics and political philosophy, to consider (and also experience) what it really is, and how it can be achieved.

Discussion of the links between virtue of character (ēthikē aretē) and happiness (eudaimonia) is one of the central concerns of ancient ethics, and a subject of much disagreement. As a result there are many varieties of eudaimonism. Two of the most influential forms are those of Aristotle[3] and the Stoics. Aristotle takes virtue and its exercise to be the most important constituent in eudaimonia but acknowledges also the importance of external goods such as health, wealth, and beauty. By contrast, the Stoics make virtue necessary and sufficient for eudaimonia and thus deny the necessity of external goods.[4]

Definition

The Definitions, a dictionary of Greek philosophical terms attributed to Plato himself but believed by modern scholars to have been written by his immediate followers in the Academy, provides the following definition of the word eudaimonia: "The good composed of all goods; an ability which suffices for living well; perfection in respect of virtue; resources sufficient for a living creature."

In his Nicomachean Ethics (§21; 1095a15–22), Aristotle says that everyone agrees that eudaimonia is the highest good for human beings, but that there is substantial disagreement on what sort of life counts as doing and living well; i.e. eudaimon:
Verbally there is a very general agreement; for both the general run of men and people of superior refinement say that it is [eudaimonia], and identify living well and faring well with being happy; but with regard to what [eudaimonia] is they differ, and the many do not give the same account as the wise. For the former think it is some plain and obvious thing like pleasure, wealth or honour… [1095a17][5]
So, as Aristotle points out, saying that eudaimon life is a life which is objectively desirable, and means living well, is not saying very much. Everyone wants to be eudaimon; and everyone agrees that being eudaimon is related to faring well and to an individual's well being. The really difficult question is to specify just what sort of activities enable one to live well. Aristotle presents various popular conceptions of the best life for human beings. The candidates that he mentions are a (1) life of pleasure, (2) a life of political activity and (3) a philosophical life.

One important move in Greek philosophy to answer the question of how to achieve eudaimonia is to bring in another important concept in ancient philosophy, "arete" ("virtue"). Aristotle says that the eudaimon life is one of "virtuous activity in accordance with reason" [1097b22–1098a20]. And even Epicurus who argues that the eudaimon life is the life of pleasure maintains that the life of pleasure coincides with the life of virtue. So the ancient ethical theorists tend to agree that virtue is closely bound up with happiness (areté is bound up with eudaimonia). However, they disagree on the way in which this is so. We shall consider the main theories in a moment, but first a warning about the proper translation of areté.

As already noted, the Greek word areté is usually translated into English as "virtue". One problem with this is that we are inclined to understand virtue in a moral sense, which is not always what the ancients had in mind. For a Greek, areté pertains to all sorts of qualities we would not regard as relevant to ethics, for example, physical beauty. So it is important to bear in mind that the sense of ‘virtue' operative in ancient ethics is not exclusively moral and includes more than states such as wisdom, courage and compassion. The sense of virtue which areté connotes would include saying something like "speed is a virtue in a horse", or "height is a virtue in a basketball player". Doing anything well requires virtue, and each characteristic activity (such as carpentry, flute playing, etc.) has its own set of virtues. The alternative translation "excellence" (or "a desirable quality") might be helpful in conveying this general meaning of the term. The moral virtues are simply a subset of the general sense in which a human being is capable of functioning well or excellently.

Positive Psychology defines Eudaimonia as a self-discovery, perceived development of one's best potentials, a sense of purpose and meaning in life, intense involvement in activities, investment of significant effort, and enjoyment of activities as personally expressive, deep relationships.[6]

Etymology and translation

In terms of its etymology, eudaimonia is an abstract noun derived from eu meaning "well" and daimon (daemon), which refers to a minor deity or a guardian spirit.[3]

Eudaimonia implies a positive and divine state of being that humanity is able to strive toward and possibly reach. A literal view of eudaimonia means achieving a state of being similar to benevolent deity, or being protected and looked after by a benevolent deity. As this would be considered the most positive state to be in, the word is often translated as 'happiness' although incorporating the divine nature of the word extends the meaning to also include the concepts of being fortunate, or blessed. Despite this etymology, however, discussions of eudaimonia in ancient Greek ethics are often conducted independently of any super-natural significance.

In his Nicomachean Ethics, (1095a15–22) Aristotle says that eudaimonia means 'doing and living well'. It is significant that synonyms for eudaimonia are living well and doing well. On the standard English translation, this would be to say that ‘happiness is doing well and living well'. The word ‘happiness' does not entirely capture the meaning of the Greek word. One important difference is that happiness often connotes being or tending to be in a certain pleasant state of mind. For example, when we say that someone is "a very happy person", we usually mean that they seem subjectively contented with the way things are going in their life. We mean to imply that they feel good about the way things are going for them. In contrast, eudaimonia is a more encompassing notion than feeling happy since events that do not contribute to one's experience of feeling happy may affect one's eudaimonia.

Eudaimonia depends on all the things that would make us happy if we knew of their existence, but quite independently of whether we do know about them. Ascribing eudaimonia to a person, then, may include ascribing such things as being virtuous, being loved and having good friends. But these are all objective judgments about someone's life: they concern a person's really being virtuous, really being loved, and really having fine friends. This implies that a person who has evil sons and daughters will not be judged to be eudaimonic even if he or she does not know that they are evil and feels pleased and contented with the way they have turned out (happy). Conversely, being loved by your children would not count towards your happiness if you did not know that they loved you (and perhaps thought that they did not), but it would count towards your eudaimonia. So eudaimonia corresponds to the idea of having an objectively good or desirable life, to some extent independently of whether one knows that certain things exist or not. It includes conscious experiences of well being, success, and failure, but also a whole lot more. (See Aristotle's discussion: Nicomachean Ethics, book 1.10–1.11.)

Because of this discrepancy between the meaning of eudaimonia and happiness, some alternative translations have been proposed. W.D. Ross suggests "well-being" and John Cooper proposes "flourishing". These translations may avoid some of the misleading associations carried by "happiness" although each tends to raise some problems of its own. In some modern texts therefore, the other alternative is to leave the term in an English form of the original Greek, as "eudaimonia".

Main views on eudaimonia and its relation to aretē

Socrates

French painter David portrayed the philosopher in The Death of Socrates (1787).

What we know of Socrates' philosophy is almost entirely derived from Plato's writings. Scholars typically divide Plato's works into three periods: the early, middle, and late periods. They tend to agree also that Plato's earliest works quite faithfully represent the teachings of Socrates and that Plato's own views, which go beyond those of Socrates, appear for the first time in the middle works such as the Phaedo and the Republic. This division will be employed here in dividing up the positions of Socrates and Plato on eudaimonia.

As with all other ancient ethical thinkers, Socrates thought that all human beings wanted eudaimonia more than anything else. (see Plato, Apology 30b, Euthydemus 280d–282d, Meno 87d–89a). However, Socrates adopted a quite radical form of eudaimonism (see above): he seems to have thought that virtue is both necessary and sufficient for eudaimonia. Socrates is convinced that virtues such as self-control, courage, justice, piety, wisdom and related qualities of mind and soul are absolutely crucial if a person is to lead a good and happy (eudaimon) life. Virtues guarantee a happy life eudaimonia. For example, in the Meno, with respect to wisdom, he says: "everything the soul endeavours or endures under the guidance of wisdom ends in happiness" [Meno 88c].

In the Apology, Socrates clearly presents his disagreement with those who think that the eudaimon life is the life of honour or pleasure, when he chastises the Athenians for caring more for riches and honour than the state of their souls.
Good Sir, you are an Athenian, a citizen of the greatest city with the greatest reputation for both wisdom and power; are you not ashamed of your eagerness to possess as much wealth, reputation, and honors as possible, while you do not care for nor give thought to wisdom or truth or the best possible state of your soul [29e].[7]
... it does not seem like human nature for me to have neglected all my own affairs and to have tolerated this neglect for so many years while I was always concerned with you, approaching each one of you like a father or an elder brother to persuade you to care for virtue. [31a–b; italics added]
It emerges a bit further on that this concern for one's soul, that one's soul might be in the best possible state, amounts to acquiring moral virtue. So Socrates' point that the Athenians should care for their souls means that they should care for their virtue, rather than pursuing honour or riches. Virtues are states of the soul. When a soul has been properly cared for and perfected it possesses the virtues. Moreover, according to Socrates, this state of the soul, moral virtue, is the most important good. The health of the soul is incomparably more important for eudaimonia than (e.g.) wealth and political power. Someone with a virtuous soul is better off than someone who is wealthy and honoured but whose soul is corrupted by unjust actions. This view is confirmed in the Crito, where Socrates gets Crito to agree that the perfection of the soul, virtue, is the most important good:
And is life worth living for us with that part of us corrupted that unjust action harms and just action benefits? Or do we think that part of us, whatever it is, that is concerned with justice and injustice, is inferior to the body? Not at all. It is much more valuable…? Much more… (47e–48a)
Here Socrates argues that life is not worth living if the soul is ruined by wrongdoing.[8] In summary, Socrates seems to think that virtue is both necessary and sufficient for eudaimonia. A person who is not virtuous cannot be happy, and a person with virtue cannot fail to be happy. We shall see later on that Stoic ethics takes its cue from this Socratic insight.

Plato

Plato's great work of the middle period, the Republic, is devoted to answering a challenge made by the sophist Thrasymachus, that conventional morality, particularly the 'virtue' of justice, actually prevents the strong man from achieving eudaimonia. Thrasymachus's views are restatements of a position which Plato discusses earlier on in his writings, in the Gorgias, through the mouthpiece of Callicles. The basic argument presented by Thrasymachus and Callicles is that justice (being just) hinders or prevents the achievement of eudaimonia because conventional morality requires that we control ourselves and hence live with un-satiated desires. This idea is vividly illustrated in book 2 of the Republic when Glaucon, taking up Thrasymachus' challenge, recounts a myth of the magical ring of Gyges. According to the myth, Gyges becomes king of Lydia when he stumbles upon a magical ring, which, when he turns it a particular way, makes him invisible, so that he can satisfy any desire he wishes without fear of punishment. When he discovers the power of the ring he kills the king, marries his wife and takes over the throne. The thrust of Glaucon's challenge is that no one would be just if he could escape the retribution he would normally encounter for fulfilling his desires at whim. But if eudaimonia is to be achieved through the satisfaction of desire, whereas being just or acting justly requires suppression of desire, then it is not in the interests of the strong man to act according to the dictates of conventional morality. (This general line of argument reoccurs much later in the philosophy of Nietzsche.) Throughout the rest of the Republic, Plato aims to refute this claim by showing that the virtue of justice is necessary for eudaimonia.

The argument of the Republic is lengthy and complex. In brief, Plato argues that virtues are states of the soul, and that the just person is someone whose soul is ordered and harmonious, with all its parts functioning properly to the person's benefit. In contrast, Plato argues that the unjust man's soul, without the virtues, is chaotic and at war with itself, so that even if he were able to satisfy most of his desires, his lack of inner harmony and unity thwart any chance he has of achieving eudaimonia. Plato's ethical theory is eudaimonistic because it maintains that eudaimonia depends on virtue. On Plato's version of the relationship, virtue is depicted as the most crucial and the dominant constituent of eudaimonia.

Aristotle

Aristotle's account is articulated in the Nicomachean Ethics and the Eudemian Ethics. In outline, for Aristotle, eudaimonia involves activity, exhibiting virtue (aretē sometimes translated as excellence) in accordance with reason. This conception of eudaimonia derives from Aristotle's essentialist understanding of human nature, the view that reason (logos sometimes translated as rationality) is unique to human beings and that the ideal function or work (ergon) of a human being is the fullest or most perfect exercise of reason. Basically, well being (eudaimonia) is gained by proper development of one's highest and most human capabilities and human beings are "the rational animal". It follows that eudaimonia for a human being is the attainment of excellence (areté) in reason.

According to Aristotle, eudaimonia actually requires activity, action, so that it is not sufficient for a person to possess a squandered ability or disposition. Eudaimonia requires not only good character but rational activity. Aristotle clearly maintains that to live in accordance with reason means achieving excellence thereby. Moreover, he claims this excellence cannot be isolated and so competencies are also required appropriate to related functions. For example, if being a truly outstanding scientist requires impressive math skills, one might say "doing mathematics well is necessary to be a first rate scientist". From this it follows that eudaimonia, living well, consists in activities exercising the rational part of the psyche in accordance with the virtues or excellency of reason [1097b22–1098a20]. Which is to say, to be fully engaged in the intellectually stimulating and fulfilling work at which one achieves well-earned success. The rest of the Nicomachean Ethics is devoted to filling out the claim that the best life for a human being is the life of excellence in accordance with reason. Since reason for Aristotle is not only theoretical but practical as well, he spends quite a bit of time discussing excellence of character, which enables a person to exercise his practical reason (i.e., reason relating to action) successfully.

Aristotle's ethical theory is eudaimonist because it maintains that eudaimonia depends on virtue. However, it is Aristotle's explicit view that virtue is necessary but not sufficient for eudaimonia. While emphasizing the importance of the rational aspect of the psyche, he does not ignore the importance of other ‘goods' such as friends, wealth, and power in a life that is eudaimonic. He doubts the likelihood of being eudaimonic if one lacks certain external goods such as ‘good birth, good children, and beauty'. So, a person who is hideously ugly or has "lost children or good friends through death" (1099b5–6), or who is isolated, is unlikely to be eudaimon. In this way, "dumb luck" (chance) can preempt one's attainment of eudaimonia.

Epicurus

Epicurus identified eudaimonia with the life of pleasure.

Epicurus' ethical theory is hedonistic. (His view proved very influential on the founders and best proponents of utilitarianism, Jeremy Bentham and John Stuart Mill.) Hedonism is the view that pleasure is the only intrinsic good and that pain is the only intrinsic bad. An object, experience or state of affairs is intrinsically valuable if it is good simply because of what it is. Intrinsic value is to be contrasted with instrumental value. An object, experience or state of affairs is instrumentally valuable if it serves as a means to what is intrinsically valuable. To see this, consider the following example. Suppose a person spends their days and nights in an office, working at not entirely pleasant activities for the purpose of receiving money. Someone asks them "why do you want the money?", and they answer: "So, I can buy an apartment overlooking the ocean, and a red sports car." This answer expresses the point that money is instrumentally valuable because its value lies in what one obtains by means of it – in this case, the money is a means to getting an apartment and a sports car and the value of making this money dependent on the price of these commodities.

Epicurus identifies the good life with the life of pleasure. He understands eudaimonia as a more or less continuous experience of pleasure and, also, freedom from pain and distress. But it is important to notice that Epicurus does not advocate that one pursue any and every pleasure. Rather, he recommends a policy whereby pleasures are maximized "in the long run". In other words, Epicurus claims that some pleasures are not worth having because they lead to greater pains, and some pains are worthwhile when they lead to greater pleasures. The best strategy for attaining a maximal amount of pleasure overall is not to seek instant gratification but to work out a sensible long term policy.

Ancient Greek ethics is eudaimonist because it links virtue and eudaimonia, where eudaimonia refers to an individual's well being. Epicurus' doctrine can be considered eudaimonist since Epicurus argues that a life of pleasure will coincide with a life of virtue. He believes that we do and ought to seek virtue because virtue brings pleasure. Epicurus' basic doctrine is that a life of virtue is the life which generates the most amount of pleasure, and it is for this reason that we ought to be virtuous. This thesis—the eudaimon life is the pleasurable life—is not a tautology as "eudaimonia is the good life" would be: rather, it is the substantive and controversial claim that a life of pleasure and absence of pain is what eudaimonia consists in.

One important difference between Epicurus' eudaimonism and that of Plato and Aristotle is that for the latter virtue is a constituent of eudaimonia, whereas Epicurus makes virtue a means to happiness. To this difference, consider Aristotle's theory. Aristotle maintains that eudaimonia is what everyone wants (and Epicurus would agree). He also thinks that eudaimonia is best achieved by a life of virtuous activity in accordance with reason. The virtuous person takes pleasure in doing the right thing as a result of a proper training of moral and intellectual character (See e.g., Nicomachean Ethics 1099a5). However, Aristotle does not think that virtuous activity is pursued for the sake of pleasure. Pleasure is a byproduct of virtuous action: it does not enter at all into the reasons why virtuous action is virtuous. Aristotle does not think that we literally aim for eudaimonia. Rather, eudaimonia is what we achieve (assuming that we aren't particularly unfortunate in the possession of external goods) when we live according to the requirements of reason. Virtue is the largest constituent in a eudaimon life. By contrast, Epicurus holds that virtue is the means to achieve happiness. His theory is eudaimonist in that he holds that virtue is indispensable to happiness; but virtue is not a constituent of a eudaimon life, and being virtuous is not (external goods aside) identical with being eudaimon. Rather, according to Epicurus, virtue is only instrumentally related to happiness. So whereas Aristotle would not say that one ought to aim for virtue in order to attain pleasure, Epicurus would endorse this claim.

The Stoics

Zeno thought happiness was a "good flow of life."

Stoic philosophy begins with Zeno of Citium c.300 BC, and was developed by Cleanthes (331–232 BC) and Chrysippus (c.280–c.206 BC) into a formidable systematic unity.[9] Zeno believed happiness was a "good flow of life"; Cleanthes suggested it was "living in agreement with nature", and Chrysippus believed it was "living in accordance with experience of what happens by nature".[9] Stoic ethics is a particularly strong version of eudaimonism. According to the Stoics, virtue is necessary and sufficient for eudaimonia. (This thesis is generally regarded as stemming from the Socrates of Plato's earlier dialogues.) We saw earlier that the conventional Greek concept of arete is not quite the same as that denoted by virtue, which has Christian connotations of charity, patience, and uprightness, since arete includes many non-moral virtues such as physical strength and beauty. However, the Stoic concept of arete is much nearer to the Christian conception of virtue, which refers to the moral virtues. However, unlike Christian understandings of virtue, righteousness or piety, the Stoic conception does not place as great an emphasis on mercy, forgiveness, self-abasement (i.e. the ritual process of declaring complete powerlessness and humility before God), charity and self-sacrificial love, though these behaviors/mentalities are not necessarily spurned by the Stoics (they are spurned by some other philosophers of Antiquity). Rather Stoicism emphasizes states such as justice, honesty, moderation, simplicity, self-discipline, resolve, fortitude, and courage (states which Christianity also encourages).

The Stoics make a radical claim that the eudaimon life is the morally virtuous life. Moral virtue is good, and moral vice is bad, and everything else, such as health, honour and riches, are merely "neutral".[9] The Stoics therefore are committed to saying that external goods such as wealth and physical beauty are not really good at all. Moral virtue is both necessary and sufficient for eudaimonia. In this, they are akin to Cynic philosophers such as Antisthenes and Diogenes in denying the importance to eudaimonia of external goods and circumstances, such as were recognized by Aristotle, who thought that severe misfortune (such as the death of one's family and friends) could rob even the most virtuous person of eudaimonia. This Stoic doctrine re-emerges later in the history of ethical philosophy in the writings of Immanuel Kant, who argues that the possession of a "good will" is the only unconditional good. One difference is that whereas the Stoics regard external goods as neutral, as neither good nor bad, Kant's position seems to be that external goods are good, but only so far as they are a condition to achieving happiness.

"Modern Moral Philosophy"

Interest in the concept of eudaimonia and ancient ethical theory more generally enjoyed a revival in the twentieth century. G. E. M. Anscombe in her article "Modern Moral Philosophy" (1958) argued that duty-based conceptions of morality are conceptually incoherent for they are based on the idea of a "law without a lawgiver".[10] She claims a system of morality conceived along the lines of the Ten Commandments depends on someone having made these rules.[11] Anscombe recommends a return to the eudaimonistic ethical theories of the ancients, particularly Aristotle, which ground morality in the interests and well being of human moral agents, and can do so without appealing to any such lawgiver.

Julia Driver in the Stanford Encyclopedia of Philosophy explains:
Anscombe's article Modern Moral Philosophy stimulated the development of virtue ethics as an alternative to Utilitarianism, Kantian Ethics, and Social Contract theories. Her primary charge in the article is that, as secular approaches to moral theory, they are without foundation. They use concepts such as "morally ought", "morally obligated", "morally right", and so forth that are legalistic and require a legislator as the source of moral authority. In the past God occupied that role, but systems that dispense with God as part of the theory are lacking the proper foundation for meaningful employment of those concepts.[12]

Modern psychology

Models of eudaimonia in psychology emerged from early work on self-actualization and the means of its accomplishment by researchers such as Erik Erikson, Gordon Allport, and Abraham Maslow.[13]

Central theories are Diener's tripartite model of subjective well-being, Ryff's Six-factor Model of Psychological Well-being, Keyes work on flourishing, and Seligman's contributions to positive psychology and his theories on authentic happiness and P.E.R.M.A. Related concepts are happiness, flourishing, quality of life, contentment,[14] and meaningful life.

Hedonism

From Wikipedia, the free encyclopedia

Hedonism is a school of thought that argues that the pursuit of pleasure and intrinsic goods are the primary or most important goals of human life. A hedonist strives to maximize net pleasure (pleasure minus pain), but when having finally gained that pleasure, happiness remains stationary.

Ethical hedonism is the idea that all people have the right to do everything in their power to achieve the greatest amount of pleasure possible to them. It is also the idea that every person's pleasure should far surpass their amount of pain. Ethical hedonism is said to have been started by Aristippus of Cyrene, a student of Socrates. He held the idea that pleasure is the highest good.

Etymology and lexicon

The name derives from the Greek word for "delight" (ἡδονισμός hēdonismos from ἡδονή hēdonē "pleasure", cognate with English sweet + suffix -ισμός -ismos "ism"). An extremely strong aversion to hedonism is hedonophobia.

History of development

Sumerian civilization

In the original Old Babylonian version of the Epic of Gilgamesh, which was written soon after the invention of writing, Siduri gave the following advice: "Fill your belly. Day and night make merry. Let days be full of joy. Dance and make music day and night [...] These things alone are the concern of men." This may represent the first recorded advocacy of a hedonistic philosophy.[3]

Ancient Egypt

Scenes of a harper entertaining guests at a feast were common in ancient Egyptian tombs (see Harper's Songs), and sometimes contained hedonistic elements, calling guests to submit to pleasure because they cannot be sure that they will be rewarded for good with a blissful afterlife. The following is a song attributed to the reign of one of the pharaohs around the time of the 12th dynasty, and the text was used in the eighteenth and nineteenth dynasties.[4][5]
Let thy desire flourish,
In order to let thy heart forget the beatifications for thee.
Follow thy desire, as long as thou shalt live.
Put myrrh upon thy head and clothing of fine linen upon thee,
Being anointed with genuine marvels of the gods' property.
Set an increase to thy good things;
Let not thy heart flag.
Follow thy desire and thy good.
Fulfill thy needs upon earth, after the command of thy heart,
Until there come for thee that day of mourning.

Classic schools of antiquity

Democritus seems to be the earliest philosopher on record to have categorically embraced a hedonistic philosophy; he called the supreme goal of life "contentment" or "cheerfulness", claiming that "joy and sorrow are the distinguishing mark of things beneficial and harmful" (DK 68 B 188).[6]

Cyrenaic school


The Cyrenaics were an ultra-hedonist Greek school of philosophy founded in the 4th century BC, supposedly by Aristippus of Cyrene, although many of the principles of the school are believed to have been formalized by his grandson of the same name, Aristippus the Younger. The school was so called after Cyrene, the birthplace of Aristippus. It was one of the earliest Socratic schools. The Cyrenaics taught that the only intrinsic good is pleasure, which meant not just the absence of pain, but positively enjoyable momentary sensations. Of these, physical ones are stronger than those of anticipation or memory. They did, however, recognize the value of social obligation, and that pleasure could be gained from altruism[citation needed]. Theodorus the Atheist was a latter exponent of hedonism who was a disciple of younger Aristippus,[7] while becoming well known for expounding atheism. The school died out within a century, and was replaced by Epicureanism.

The Cyrenaics were known for their skeptical theory of knowledge. They reduced logic to a basic doctrine concerning the criterion of truth.[8] They thought that we can know with certainty our immediate sense-experiences (for instance, that I am having a sweet sensation now) but can know nothing about the nature of the objects that cause these sensations (for instance, that the honey is sweet).[9] They also denied that we can have knowledge of what the experiences of other people are like.[10] All knowledge is immediate sensation. These sensations are motions which are purely subjective, and are painful, indifferent or pleasant, according as they are violent, tranquil or gentle.[9][11] Further, they are entirely individual and can in no way be described as constituting absolute objective knowledge. Feeling, therefore, is the only possible criterion of knowledge and of conduct.[9] Our ways of being affected are alone knowable. Thus the sole aim for everyone should be pleasure.

Cyrenaicism deduces a single, universal aim for all people which is pleasure. Furthermore, all feeling is momentary and homogeneous. It follows that past and future pleasure have no real existence for us, and that among present pleasures there is no distinction of kind.[11] Socrates had spoken of the higher pleasures of the intellect; the Cyrenaics denied the validity of this distinction and said that bodily pleasures, being more simple and more intense, were preferable.[12] Momentary pleasure, preferably of a physical kind, is the only good for humans. However some actions which give immediate pleasure can create more than their equivalent of pain. The wise person should be in control of pleasures rather than be enslaved to them, otherwise pain will result, and this requires judgement to evaluate the different pleasures of life.[13] Regard should be paid to law and custom, because even though these things have no intrinsic value on their own, violating them will lead to unpleasant penalties being imposed by others.[12] Likewise, friendship and justice are useful because of the pleasure they provide.[12] Thus the Cyrenaics believed in the hedonistic value of social obligation and altruistic behaviour.

Epicureanism

Epicureanism is a system of philosophy based upon the teachings of Epicurus (c. 341–c. 270 BC), founded around 307 BC. Epicurus was an atomic materialist, following in the steps of Democritus and Leucippus. His materialism led him to a general stance against superstition or the idea of divine intervention. Following Aristippus—about whom very little is known—Epicurus believed that the greatest good was to seek modest, sustainable "pleasure" in the form of a state of tranquility and freedom from fear (ataraxia) and absence of bodily pain (aponia) through knowledge of the workings of the world and the limits of our desires. The combination of these two states is supposed to constitute happiness in its highest form. Although Epicureanism is a form of hedonism, insofar as it declares pleasure as the sole intrinsic good, its conception of absence of pain as the greatest pleasure and its advocacy of a simple life make it different from "hedonism" as it is commonly understood.


In the Epicurean view, the highest pleasure (tranquility and freedom from fear) was obtained by knowledge, friendship and living a virtuous and temperate life. He lauded the enjoyment of simple pleasures, by which he meant abstaining from bodily desires, such as sex and appetites, verging on asceticism. He argued that when eating, one should not eat too richly, for it could lead to dissatisfaction later, such as the grim realization that one could not afford such delicacies in the future. Likewise, sex could lead to increased lust and dissatisfaction with the sexual partner. Epicurus did not articulate a broad system of social ethics that has survived but had a unique version of the Golden Rule.
It is impossible to live a pleasant life without living wisely and well and justly (agreeing "neither to harm nor be harmed"),[14] and it is impossible to live wisely and well and justly without living a pleasant life.[15]
Epicureanism was originally a challenge to Platonism, though later it became the main opponent of Stoicism. Epicurus and his followers shunned politics. After the death of Epicurus, his school was headed by Hermarchus; later many Epicurean societies flourished in the Late Hellenistic era and during the Roman era (such as those in Antiochia, Alexandria, Rhodes and Ercolano). The poet Lucretius is its most known Roman proponent. By the end of the Roman Empire, having undergone Christian attack and repression, Epicureanism had all but died out, and would be resurrected in the 17th century by the atomist Pierre Gassendi, who adapted it to the Christian doctrine.

Some writings by Epicurus have survived. Some scholars consider the epic poem On the Nature of Things by Lucretius to present in one unified work the core arguments and theories of Epicureanism. Many of the papyrus scrolls unearthed at the Villa of the Papyri at Herculaneum are Epicurean texts. At least some are thought to have belonged to the Epicurean Philodemus.

Yangism

Yangism has been described as a form of psychological and ethical egoism. The Yangist philosophers believed in the importance of maintaining self-interest through "keeping one's nature intact, protecting one's uniqueness, and not letting the body be tied by other things." Disagreeing with the Confucian virtues of li (propriety), ren (humaneness), and yi (righteousness) and the Legalist virtue of fa (law), the Yangists saw wei wo, or "everything for myself," as the only virtue necessary for self-cultivation. Individual pleasure is considered desirable, like in hedonism, but not at the expense of the health of the individual. The Yangists saw individual well-being as the prime purpose of life, and considered anything that hindered that well-being immoral and unnecessary.

The main focus of the Yangists was on the concept of xing, or human nature, a term later incorporated by Mencius into Confucianism. The xing, according to sinologist A. C. Graham, is a person's "proper course of development" in life. Individuals can only rationally care for their own xing, and should not naively have to support the xing of other people, even if it means opposing the emperor. In this sense, Yangism is a "direct attack" on Confucianism, by implying that the power of the emperor, defended in Confucianism, is baseless and destructive, and that state intervention is morally flawed.

The Confucian philosopher Mencius depicts Yangism as the direct opposite of Mohism, while Mohism promotes the idea of universal love and impartial caring, the Yangists acted only "for themselves," rejecting the altruism of Mohism. He criticized the Yangists as selfish, ignoring the duty of serving the public and caring only for personal concerns. Mencius saw Confucianism as the "Middle Way" between Mohism and Yangism.

Judaism

Judaism believes that mankind was created for pleasure, as God placed Adam and Eve in the Garden of Eden—Eden being the Hebrew word for "pleasure." In recent years, Rabbi Noah Weinberg articulated five different levels of pleasure; connecting with God is the highest possible pleasure.

Christianity

Ethical hedonism as part of Christian theology has also been a concept in some evangelical circles, particularly in those of the Reformed tradition.[16] The term Christian Hedonism was first coined by Reformed Baptist theologian John Piper in his 1986 book Desiring God: “My shortest summary of it is: God is most glorified in us when we are most satisfied in him. Or: The chief end of man is to glorify God by enjoying him forever. Does Christian Hedonism make a god out of pleasure? No. It says that we all make a god out of what we take most pleasure in.” [16] Piper states his term may describe the theology of Jonathan Edwards, who in 1812 referred to “a future enjoyment of him [God] in heaven.”[17] Already in the 17th century, the atomist Pierre Gassendi had adapted Epicureanism to the Christian doctrine.

Hinduism

The concept of hedonism is also found in the Hindu scriptures.

Utilitarianism

Utilitarianism addresses problems with moral motivation neglected by Kantianism by giving a central role to happiness. It is an ethical theory holding that the proper course of action is the one that maximizes the overall good of the society.[20] It is thus one form of consequentialism, meaning that the moral worth of an action is determined by its resulting outcome. The most influential contributors to this theory are considered to be the 18th and 19th-century British philosophers Jeremy Bentham and John Stuart Mill. Conjoining hedonism—as a view as to what is good for people—to utilitarianism has the result that all action should be directed toward achieving the greatest total amount of happiness (see Hedonic calculus). Though consistent in their pursuit of happiness, Bentham and Mill's versions of hedonism differ. There are two somewhat basic schools of thought on hedonism:[1]
  • One school, grouped around Bentham, defends a quantitative approach. Bentham believed that the value of a pleasure could be quantitatively understood. Essentially, he believed the value of pleasure to be its intensity multiplied by its duration - so it was not just the number of pleasures, but their intensity and how long they lasted that must be taken into account.
  • Other proponents, like Mill, argue a qualitative approach. Mill believed that there can be different levels of pleasure - higher quality pleasure is better than lower quality pleasure. Mill also argues that simpler beings (he often refers to pigs) have an easier access to the simpler pleasures; since they do not see other aspects of life, they can simply indulge in their lower pleasures. The more elaborate beings tend to spend more thought on other matters and hence lessen the time for simple pleasure. It is therefore more difficult for them to indulge in such "simple pleasures" in the same manner.

Libertinage

An extreme form of hedonism that views moral and sexual restraint as either unnecessary or harmful. Famous proponents are Marquis de sade[21][22] and John Wilmot[23]

Contemporary approaches

Contemporary proponents of hedonism include Swedish philosopher Torbjörn Tännsjö,[24] Fred Feldman.[25] and Spanish ethic philosopher Esperanza Guisán (published a "Hedonist manifesto" in 1990).[26]

Michel Onfray

Michel Onfray, contemporary hedonist philosopher

A dedicated contemporary hedonist philosopher and writer on the history of hedonistic thought is the French Michel Onfray. He has written two books directly on the subject (L'invention du plaisir : fragments cyréaniques[27] and La puissance d'exister : Manifeste hédoniste).[28] He defines hedonism "as an introspective attitude to life based on taking pleasure yourself and pleasuring others, without harming yourself or anyone else."[29] Onfray's philosophical project is to define an ethical hedonism, a joyous utilitarianism, and a generalized aesthetic of sensual materialism that explores how to use the brain's and the body's capacities to their fullest extent -- while restoring philosophy to a useful role in art, politics, and everyday life and decisions."[30]

Onfray's works "have explored the philosophical resonances and components of (and challenges to) science, painting, gastronomy, sex and sensuality, bioethics, wine, and writing. His most ambitious project is his projected six-volume Counter-history of Philosophy,"[30] of which three have been published. For him "In opposition to the ascetic ideal advocated by the dominant school of thought, hedonism suggests identifying the highest good with your own pleasure and that of others; the one must never be indulged at the expense of sacrificing the other. Obtaining this balance – my pleasure at the same time as the pleasure of others – presumes that we approach the subject from different angles – political, ethical, aesthetic, erotic, bioethical, pedagogical, historiographical…."

For this he has "written books on each of these facets of the same world view."[31] His philosophy aims for "micro-revolutions", or "revolutions of the individual and small groups of like-minded people who live by his hedonistic, libertarian values."[32]

Abolitionism

David Pearce, transhumanist philosopher

The Abolitionist Society is a transhumanist group calling for the abolition of suffering in all sentient life through the use of advanced biotechnology. Their core philosophy is negative utilitarianismDavid Pearce is a theorist of this perspective and he believes and promotes the idea that there exists a strong ethical imperative for humans to work towards the abolition of suffering in all sentient life. His book-length internet manifesto The Hedonistic Imperative[33] outlines how technologies such as genetic engineering, nanotechnology, pharmacology, and neurosurgery could potentially converge to eliminate all forms of unpleasant experience among human and non-human animals, replacing suffering with gradients of well-being, a project he refers to as "paradise engineering".[34] A transhumanist and a vegan,[35] Pearce believes that we (or our future posthuman descendants) have a responsibility not only to avoid cruelty to animals within human society but also to alleviate the suffering of animals in the wild.

In a talk David Pearce gave at the Future of Humanity Institute and at the Charity International 'Happiness Conference' he said "Sadly, what won't abolish suffering, or at least not on its own, is socio-economic reform, or exponential economic growth, or technological progress in the usual sense, or any of the traditional panaceas for solving the world's ills. Improving the external environment is admirable and important; but such improvement can't recalibrate our hedonic treadmill above a genetically constrained ceiling. Twin studies confirm there is a [partially] heritable set-point of well-being - or ill-being - around which we all tend to fluctuate over the course of a lifetime. This set-point varies between individuals. [It's possible to lower an individual's hedonic set-point by inflicting prolonged uncontrolled stress; but even this re-set is not as easy as it sounds: suicide-rates typically go down in wartime; and six months after a quadriplegia-inducing accident, studies[citation needed] suggest that we are typically neither more nor less unhappy than we were before the catastrophic event.] Unfortunately, attempts to build an ideal society can't overcome this biological ceiling, whether utopias of the left or right, free-market or socialist, religious or secular, futuristic high-tech or simply cultivating one's garden. Even if everything that traditional futurists have asked for is delivered - eternal youth, unlimited material wealth, morphological freedom, superintelligence, immersive VR, molecular nanotechnology, etc - there is no evidence that our subjective quality of life would on average significantly surpass the quality of life of our hunter-gatherer ancestors - or a New Guinea tribesman today - in the absence of reward pathway enrichment. This claim is difficult to prove in the absence of sophisticated neuroscanning; but objective indices of psychological distress e.g. suicide rates, bear it out. Unenhanced humans will still be prey to the spectrum of Darwinian emotions, ranging from terrible suffering to petty disappointments and frustrations - sadness, anxiety, jealousy, existential angst. Their biology is part of "what it means to be human". Subjectively unpleasant states of consciousness exist because they were genetically adaptive. Each of our core emotions had a distinct signalling role in our evolutionary past: they tended to promote behaviours that enhanced the inclusive fitness of our genes in the ancestral environment."[36]

Hedonism as a scientific basis for long-term future forecasting

Russian physicist and philosopher Victor Argonov argues that hedonism is not only a philosophical but also a verifiable scientific hypothesis. In 2014 he suggested "postulates of pleasure principle" confirmation of which would lead to a new scientific discipline, hedodynamics. Hedodynamics would be able to forecast the distant future development of human civilization and even the probable structure and psychology of other rational beings within the universe.[37] In order to build such a theory, science must discover the neural correlate of pleasure - neurophysiological parameter unambiguously corresponding to the feeling of pleasure (hedonic tone).

According to Argonov, posthumans will be able to reprogram their motivations in an arbitrary manner (to get pleasure from any programmed activity).[38] And if pleasure principle postulates are true, then general direction of civilization development is obvious: maximization of integral happiness in posthuman life (product of life span and average happiness). Posthumans will avoid constant pleasure stimulation, because it is incompatible with rational behavior required to prolong life. However, in average, they can become much happier than modern humans.

Many other aspects of posthuman society could be predicted by hedodynamics if the neural correlate of pleasure were discovered. For example, optimal number of individuals, their optimal body size (whether it matters for happiness or not) and the degree of aggression.

Criticisms

Critics of hedonism have objected to its exclusive concentration on pleasure as valuable.

In particular, G. E. Moore offered a thought experiment in criticism of pleasure as the sole bearer of value: he imagined two worlds—one of exceeding beauty and the other a heap of filth. Neither of these worlds will be experienced by anyone. The question, then, is if it is better for the beautiful world to exist than the heap of filth. In this Moore implied that states of affairs have value beyond conscious pleasure, which he said spoke against the validity of hedonism.[39]

Islamic view

In Quran, God admonished mankind not to love the worldly pleasures, since it is related with greedy and source of sinful habit. He also threatened those who prefer worldly life rather than hereafter with Hell.
Those who choose the worldly life and its pleasures will be given proper recompense for their deeds in this life and will not suffer any loss. Such people will receive nothing in the next life except Hell fire. Their deeds will be made devoid of all virtue and their efforts will be in vain.

New DNA Synthesis Method Could Soon Build a Genome in a Day

dna_helix_hi_tech_genetic_engineering

Synthetic biologists are the computer programmers of biology. Their code? DNA.

The whole enterprise sounds fantastical: you insert new snippets of DNA code—in the form of a chain of A, T, C, G letters—into an organism, and bam! Suddenly you have bacteria that can make anti-malaria drugs or cells that can solve complicated logic problems like a computer.

Except it’s not that simple. The basis of synthetic biology is DNA—often a lot of it, in the form of many genes. Making an average gene from scratch costs several hundreds of dollars and weeks of time. Imagine a programmer taking a month to type a new line of code, and you’ll likely understand a synthetic biologist’s frustration.

Now, a new method published in the July issue of Nature Biotechnology promises to revolutionize DNA synthesis with a faster, cheaper, and more accurate approach. Taking inspiration from nature, a team at UC Berkeley cracked a decades-old puzzle that allowed them to tap into the superpowers of TdT, a protein inside our own bodies specialized for making genes.

The new technology is so simple and non-toxic that the team believes it could lead to “DNA printers” for scientists (or even biohackers), similar to 3D printers available at workshops today.

“If you’re a researcher or bioengineer and you have an instrument that streamlines DNA synthesis, a ‘DNA printer,’ you can test your ideas faster and try out more new ideas. I think it will lead to a lot of innovation,” said study author Dan Arlow.

“It’s the future. It’s going to be enormous,” said Dr. George Church, a pioneering geneticist and synthetic biologist at Harvard University who was not involved in the study. Church is heading a massive DNA synthesis project called GP-WRITE, which aims to build “superhero” cells resilient against all types of diseases, including infections and aging.

The new method, if further optimized, could propel GP-WRITE towards its goal, and revolutionize our ability to build new genomes—and perhaps organisms—from scratch.

DNA Blues

The most popular DNA synthesis method today is a near 40-year-old legacy technique rooted in organic chemistry. The method takes the four letters of DNA and jams them together one by one using a mix of toxic chemicals. Each letter takes three minutes to add and is prone to errors. To the exasperation of synthetic biologists, custom-made DNA chains typically cap out at only 200 letters before too many mistakes build up—a sliver of the thousands of letters normally present in a gene.

Our bodies, in contrast, can add 1,000 letters per second with virtually no errors. Thanks to a variety of DNA builders called polymerases, our cells use a single strand of DNA as a template and efficiently make a complimentary new strand—substituting A for T, C for G, and vice-versa.

As early as the 1960s, scientists dreamed of tapping into polymerases to simplify DNA synthesis. They even honed in on a specific candidate: TdT, which unlike its brethren, attaches DNA letters to an existing chain without the requirement of a template at 200 letters per minute.

TdT’s creative potential comes from its natural role. The polymerase writes new variations of genes that make antibodies, which helps our bodies recognize new invaders without previous experience.

But there’s a catch: the enzyme is a wild card in that it attaches DNA letters randomly. This obviously wouldn’t work for scientists who need a specific genetic sequence.

What’s more, the enzyme is extremely picky. Normally, scientists slightly modify the chemical structure of each DNA letter to allow them to be added one at a time. TdT isn’t keen on working with these modified letters. One system, for example, takes roughly an hour to add a single letter—far too slow to be of any practical use.

Scientists have also tried to “dig a hole” into TdT, so that it grabs onto the modified DNA letters better. That method also failed: modifying the enzyme while preserving its activity was a lot harder than expected.

For years scientists have been stumped as to how to convince the enzyme to add one specified letter at a time.

This is where the Berkeley team comes in.

Outside the Box

The winning trick is to tether each DNA letter directly to the enzyme.

The team starts with four separate pools of DNA letters. The letters are literally dissolved in water. Each one is loosely attached to a copy of TdT via a chemical link that can be destroyed.

When adding a DNA letter, the enzyme basically drags each letter to the DNA chain. Here’s the clever part: because the letter is attached to the bulky TdT, the enzyme itself naturally blocks other letters from adding on, simply because there’s no space for another TdT-DNA letter combo to react with the DNA chain.

To further extend the chain, the team fished out the product and snipped the tether to free the enzyme and expose the tail-end of the DNA chain. The chain is now ready for another round of addition.

The idea is counter-intuitive because scientists often keep the enzyme around. But TdT is cheap and easy to make using bacteria, explained Dr. Jay Keasling, who directed the study.

“Rather than re-using an enzyme as a catalyst,” which is what all previous attempts tried to do, he said, “[we thought] let’s just throw it away.”

In a proof-of-concept trial, the team manually made a 10-letter DNA strand using the modified TdTs. The speed was astonishing: they could add a new DNA letter in just 10 to 20 seconds—roughly 18 times faster than current approaches.

Although the snipping step still takes about a minute, which adds up when synthesizing long DNA strands, the new technique comes out on top compared to conventional methods in terms of speediness. Rather than weeks, making a new gene from scratch will likely only take a day.

“A key advantage of this approach is that the backbone of the DNA—the part that actually does the chemical reaction—is just like natural DNA, so we can try to get the full speed out of the enzyme,” explained Arlow.

Natural DNA Synthesis

The team still has a few tweaks to make before their DNA building method makes it mainstream.

Part of it is accuracy. So far, after decades of fine-tuning, conventional DNA synthesis hits a 99.5 percent accuracy for each step. The Berkeley team’s method works out to be about 98 percent—a slight difference that nevertheless adds up during thousands of rounds.

“[It] is not too bad for a first go at this 50-plus-year-old problem,” said Arlow, adding that the goal is to make it to 99.9 percent to make a gene-length DNA strand of over 1,000 letters.

“We think that we’ll catch up soon and believe that we can push the system far beyond the current limitations of chemical synthesis,” said study author Sebastian Palluk. “Our dream is to directly synthesize gene-length sequences and get them to researchers within a few days.”

“It really is one of the first out of the starting gates with a novel idea,” said Church. The clever hack may just be what it takes to revolutionize synthetic biology’s hopes of writing new genes and new organisms. The dream of storing massive amounts of data in DNA could also be possible.

This study is just a glimpse of the exponential future of synthetic biology. As Church put it, “stay tuned.”

Utilitarianism

From Wikipedia, the free encyclopedia

Utilitarianism is an ethical theory that states that the best action is the one that maximizes utility. "Utility" is defined in various ways, usually in terms of the well-being of sentient entities. Jeremy Bentham, the founder of utilitarianism, described utility as the sum of all pleasure that results from an action, minus the suffering of anyone involved in the action. Utilitarianism is a version of consequentialism, which states that the consequences of any action are the only standard of right and wrong. Unlike other forms of consequentialism, such as egoism, utilitarianism considers the interests of all beings equally.

Proponents of utilitarianism have disagreed on a number of points, such as whether actions should be chosen based on their likely results (act utilitarianism) or whether agents should conform to rules that maximize utility (rule utilitarianism). There is also disagreement as to whether total (total utilitarianism) or average (average utilitarianism) utility should be maximized.

Though the seeds of the theory can be found in the hedonists Aristippus and Epicurus, who viewed happiness as the only good, the tradition of utilitarianism properly began with Bentham, and has included John Stuart Mill, Henry Sidgwick, R. M. Hare, David Braybrooke, and Peter Singer. It has been applied to social welfare economics, the crisis of global poverty, the ethics of raising animals for food and the importance of avoiding existential risks to humanity.

Etymology

Benthamism, the utilitarian philosophy founded by Jeremy Bentham, was substantially modified by his successor John Stuart Mill, who popularized the word 'Utilitarianism'.[1] In 1861, Mill acknowledged in a footnote that, though "believing himself to be the first person who brought the word 'utilitarian' into use, he did not invent it. Rather, he adopted it from a passing expression in" John Galt's 1821 novel Annals of the Parish.[2] Mill seems to have been unaware that Bentham had used the term 'utilitarian' in his 1781 letter to George Wilson and his 1802 letter to Étienne Dumont.[1]

Historical background

Chinese philosophy

In Chinese philosophy, the Mohists and their successors the "Chinese Legalists"[citation needed] might be considered utilitarians, or at least the "earliest form of consequentialism". The fourth century witnessed the emergence of particular concerns for them, including discussions polarizing the concepts of self and private, commonly used in conjunction with profit and associated with fragmentation, division, partiality, and one-sidelines, with that of the state and "public", represented by the duke and referring to what is official or royal, that is, the ruler himself, associated with unity, wholeness, objectivity, and universality. The later denotes the "universal Way".[3]

However, the Mohists did not focus on emotional happiness, but promoted objective public goods: material wealth, a large population or family, and social order.[4] On the other hand, the "Legalist" Han Fei "is motivated almost totally from the ruler's point of view."[5]

Western philosophy

The importance of happiness as an end for humans has long been recognized. Forms of hedonism were put forward by Aristippus and Epicurus; Aristotle argued that eudaimonia is the highest human good and Augustine wrote that "all men agree in desiring the last end, which is happiness." Happiness was also explored in depth by Aquinas.[6][7][8][9][10] Different varieties of consequentialism also existed in the ancient and medieval world, like the state consequentialism of Mohism or the political philosophy of Niccolò Machiavelli. Mohist consequentialism advocated communitarian moral goods including political stability, population growth, and wealth, but did not support the utilitarian notion of maximizing individual happiness.[11] Machiavelli was also an exponent of consequentialism. He believed that the actions of a state, however cruel or ruthless they may be, must contribute towards the common good of a society.[12] Utilitarianism as a distinct ethical position only emerged in the eighteenth century.

Although utilitarianism is usually thought to start with Jeremy Bentham, there were earlier writers who presented theories that were strikingly similar. In An Enquiry Concerning the Principles of Morals, David Hume writes:[13]
In all determinations of morality, this circumstance of public utility is ever principally in view; and wherever disputes arise, either in philosophy or common life, concerning the bounds of duty, the question cannot, by any means, be decided with greater certainty, than by ascertaining, on any side, the true interests of mankind. If any false opinion, embraced from appearances, has been found to prevail; as soon as farther experience and sounder reasoning have given us juster notions of human affairs, we retract our first sentiment, and adjust anew the boundaries of moral good and evil.
Hume studied the works of, and corresponded with, Francis Hutcheson, and it was he who first introduced a key utilitarian phrase. In An Inquiry into the Original of Our Ideas of Beauty and Virtue (1725), Hutcheson says[14] when choosing the most moral action, virtue is in proportion to the number of people a particular action brings happiness to. In the same way, moral evil, or vice, is proportionate to the number of people made to suffer. The best action is the one that procures the greatest happiness of the greatest numbers—and the worst is the one that causes the most misery.
In the first three editions of the book, Hutcheson included various mathematical algorithms "...to compute the Morality of any Actions." In this, he pre-figured the hedonic calculus of Bentham.

Some claim that John Gay developed the first systematic theory of utilitarian ethics.[15] In Concerning the Fundamental Principle of Virtue or Morality (1731), Gay argues that:[16]
happiness, private happiness, is the proper or ultimate end of all our actions… each particular action may be said to have its proper and peculiar end…(but)…. they still tend or ought to tend to something farther; as is evident from hence, viz. that a man may ask and expect a reason why either of them are pursued: now to ask the reason of any action or pursuit, is only to enquire into the end of it: but to expect a reason, i.e. an end, to be assigned for an ultimate end, is absurd. To ask why I pursue happiness, will admit of no other answer than an explanation of the terms.
This pursuit of happiness is given a theological basis:[17]
Now it is evident from the nature of God, viz. his being infinitely happy in himself from all eternity, and from his goodness manifested in his works, that he could have no other design in creating mankind than their happiness; and therefore he wills their happiness; therefore the means of their happiness: therefore that my behaviour, as far as it may be a means of the happiness of mankind, should be such…thus the will of God is the immediate criterion of Virtue, and the happiness of mankind the criterion of the wilt of God; and therefore the happiness of mankind may be said to be the criterion of virtue, but once removed…(and)… I am to do whatever lies in my power towards promoting the happiness of mankind.
Modern Utilitarianism by Thomas Rawson Birks 1874

Gay's theological utilitarianism was developed and popularized by William Paley. It has been claimed that Paley was not a very original thinker and that the philosophical part of his treatise on ethics is "an assemblage of ideas developed by others and is presented to be learned by students rather than debated by colleagues."[18] Nevertheless, his book The Principles of Moral and Political Philosophy (1785) was a required text at Cambridge[18] and Smith says that Paley's writings were "once as well known in American colleges as were the readers and spellers of William McGuffey and Noah Webster in the elementary schools."[19] Although now largely missing from the philosophical canon, Schneewind writes that "utilitarianism first became widely known in England through the work of William Paley."[20] The now forgotten significance of Paley can be judged from the title of Thomas Rawson Birks's 1874 work Modern Utilitarianism or the Systems of Paley, Bentham and Mill Examined and Compared.

Apart from restating that happiness as an end is grounded in the nature of God, Paley also discusses the place of rules. He writes:[21]
...actions are to be estimated by their tendency. Whatever is expedient, is right. It is the utility of any moral rule alone, which constitutes the obligation of it.

But to all this there seems a plain objection, viz. that many actions are useful, which no man in his senses will allow to be right. There are occasions, in which the hand of the assassin would be very useful… The true answer is this; that these actions, after all, are not useful, and for that reason, and that alone, are not right.

To see this point perfectly, it must be observed that the bad consequences of actions are twofold, particular and general. The particular bad consequence of an action, is the mischief which that single action directly and immediately occasions. The general bad consequence is, the violation of some necessary or useful general rule…

You cannot permit one action and forbid another, without showing a difference between them. Consequently, the same sort of actions must be generally permitted or generally forbidden. Where, therefore, the general permission of them would be pernicious, it becomes necessary to lay down and support the rule which generally forbids them.

Classical utilitarianism

Jeremy Bentham


Bentham's book An Introduction to the Principles of Morals and Legislation was printed in 1780 but not published until 1789. It is possible that Bentham was spurred on to publish after he saw the success of Paley's The Principles of Moral and Political Philosophy.[22] Bentham's book was not an immediate success[23] but his ideas were spread further when Pierre Étienne Louis Dumont translated edited selections from a variety of Bentham's manuscripts into French. Traité de legislation civile et pénale was published in 1802 and then later retranslated back into English by Hildreth as The Theory of Legislation, although by this time significant portions of Dumont's work had already been retranslated and incorporated into Sir John Bowring's edition of Bentham's works, which was issued in parts between 1838 and 1843.

Bentham's work opens with a statement of the principle of utility:[24]
Nature has placed mankind under the governance of two sovereign masters, pain and pleasure. It is for them alone to point out what we ought to do… By the principle of utility is meant that principle which approves or disapproves of every action whatsoever according to the tendency it appears to have to augment or diminish the happiness of the party whose interest is in question: or, what is the same thing in other words to promote or to oppose that happiness. I say of every action whatsoever, and therefore not only of every action of a private individual, but of every measure of government.
In Chapter IV, Bentham introduces a method of calculating the value of pleasures and pains, which has come to be known as the hedonic calculus. Bentham says that the value of a pleasure or pain, considered by itself, can be measured according to its intensity, duration, certainty/uncertainty and propinquity/remoteness. In addition, it is necessary to consider "the tendency of any act by which it is produced" and, therefore, to take account of the act's fecundity, or the chance it has of being followed by sensations of the same kind and its purity, or the chance it has of not being followed by sensations of the opposite kind. Finally, it is necessary to consider the extent, or the number of people affected by the action.

Perhaps aware that Hutcheson eventually removed his algorithms for calculating the greatest happiness because they "appear'd useless, and were disagreeable to some readers",[25] Bentham contends that there is nothing novel or unwarranted about his method, for "in all this there is nothing but what the practice of mankind, wheresoever they have a clear view of their own interest, is perfectly conformable to."

Rosen warns that descriptions of utilitarianism can bear "little resemblance historically to utilitarians like Bentham and J. S. Mill" and can be more "a crude version of act utilitarianism conceived in the twentieth century as a straw man to be attacked and rejected."[26] It is a mistake to think that Bentham is not concerned with rules. His seminal work is concerned with the principles of legislation and the hedonic calculus is introduced with the words "Pleasures then, and the avoidance of pains, are the ends that the legislator has in view." In Chapter VII, Bentham says: "The business of government is to promote the happiness of the society, by punishing and rewarding… In proportion as an act tends to disturb that happiness, in proportion as the tendency of it is pernicious, will be the demand it creates for punishment."

The question then arises as to when, if at all, it might be legitimate to break the law. This is considered in The Theory of Legislation, where Bentham distinguishes between evils of the first and second orders. Those of the first order are the more immediate consequences; those of the second are when the consequences spread through the community causing "alarm" and "danger".
It is true there are cases in which, if we confine ourselves to the effects of the first order, the good will have an incontestable preponderance over the evil. Were the offence considered only under this point of view, it would not be easy to assign any good reasons to justify the rigour of the laws. Every thing depends upon the evil of the second order; it is this which gives to such actions the character of crime, and which makes punishment necessary. Let us take, for example, the physical desire of satisfying hunger. Let a beggar, pressed by hunger, steal from a rich man's house a loaf, which perhaps saves him from starving, can it be possible to compare the good which the thief acquires for himself, with the evil which the rich man suffers? … It is not on account of the evil of the first order that it is necessary to erect these actions into offences, but on account of the evil of the second order.[27]

John Stuart Mill

Mill was brought up as a Benthamite with the explicit intention that he would carry on the cause of utilitarianism.[28] Mill's book Utilitarianism first appeared as a series of three articles published in Fraser's Magazine in 1861 and was reprinted as a single book in 1863.[29][citation needed]

Higher and lower pleasures

Mill rejects a purely quantitative measurement of utility and says:[30]
It is quite compatible with the principle of utility to recognize the fact, that some kinds of pleasure are more desirable and more valuable than others. It would be absurd that while, in estimating all other things, quality is considered as well as quantity, the estimation of pleasures should be supposed to depend on quantity alone.
The word utility is used to mean general well-being or happiness, and Mill's view is that utility is the consequence of a good action. Utility, within the context of utilitarianism, refers to people performing actions for social utility. With social utility, he means the well-being of many people. Mill's explanation of the concept of utility in his work, Utilitarianism, is that people really do desire happiness, and since each individual desires their own happiness, it must follow that all of us desire the happiness of everyone, contributing to a larger social utility. Thus, an action that results in the greatest pleasure for the utility of society is the best action, or as Jeremy Bentham, the founder of early Utilitarianism put it, as the greatest happiness of the greatest number.

Mill not only viewed actions as a core part of utility, but as the directive rule of moral human conduct. The rule being that we should only be committing actions that provide pleasure to society. This view of pleasure was hedonistic, as it pursued the thought that pleasure is the highest good in life. This concept was adopted by Jeremy Bentham, the founder of Utilitarianism, and can be seen in his works. According to Mill, good actions result in pleasure, and that there is no higher end than pleasure. Mill says that good actions lead to pleasure and define good character. Better put, the justification of character, and whether an action is good or not, is based on how the person contributes to the concept of social utility. In the long run the best proof of a good character is good actions; and resolutely refuse to consider any mental disposition as good, of which the predominant tendency is to produce bad conduct. In the last chapter of Utilitarianism, Mill concludes that justice, as a classifying factor of our actions (being just or unjust) is one of the certain moral requirements, and when the requirements are all regarded collectively, they are viewed as greater according to this scale of "social utility" as Mill puts it.

He also notes that, contrary to what its critics might say, there is "no known Epicurean theory of life which does not assign to the pleasures of the intellect… a much higher value as pleasures than to those of mere sensation." However, he accepts that this is usually because the intellectual pleasures are thought to have circumstantial advantages, i.e. "greater permanency, safety, uncostliness, &c." Instead, Mill will argue that some pleasures are intrinsically better than others.

The accusation that hedonism is "doctrine worthy only of swine" has a long history. In Nicomachean Ethics (Book 1 Chapter 5), Aristotle says that identifying the good with pleasure is to prefer a life suitable for beasts. The theological utilitarians had the option of grounding their pursuit of happiness in the will of God; the hedonistic utilitarians needed a different defence. Mill's approach is to argue that the pleasures of the intellect are intrinsically superior to physical pleasures.
Few human creatures would consent to be changed into any of the lower animals, for a promise of the fullest allowance of a beast's pleasures; no intelligent human being would consent to be a fool, no instructed person would be an ignoramus, no person of feeling and conscience would be selfish and base, even though they should be persuaded that the fool, the dunce, or the rascal is better satisfied with his lot than they are with theirs… A being of higher faculties requires more to make him happy, is capable probably of more acute suffering, and certainly accessible to it at more points, than one of an inferior type; but in spite of these liabilities, he can never really wish to sink into what he feels to be a lower grade of existence… It is better to be a human being dissatisfied than a pig satisfied; better to be Socrates dissatisfied than a fool satisfied. And if the fool, or the pig, are of a different opinion, it is because they only know their own side of the question…[31]
Mill argues that if people who are "competently acquainted" with two pleasures show a decided preference for one even if it be accompanied by more discontent and "would not resign it for any quantity of the other", then it is legitimate to regard that pleasure as being superior in quality. Mill recognizes that these "competent judges" will not always agree, and states that, in cases of disagreement, the judgment of the majority is to be accepted as final. Mill also acknowledges that "many who are capable of the higher pleasures, occasionally, under the influence of temptation, postpone them to the lower. But this is quite compatible with a full appreciation of the intrinsic superiority of the higher." Mill says that this appeal to those who have experienced the relevant pleasures is no different from what must happen when assessing the quantity of pleasure, for there is no other way of measuring "the acutest of two pains, or the intensest of two pleasurable sensations." "It is indisputable that the being whose capacities of enjoyment are low, has the greatest chance of having them fully satisfied; and a highly-endowed being will always feel that any happiness which he can look for, as the world is constitute, is imperfect."[32]

Mill also thinks that “intellectual pursuits have value out of proportion to the amount of contentment or pleasure (the mental state) that they produce”.[33] Mill also says that people should pursue these grand ideals, because if they choose to have gratification from petty pleasures, “some displeasure will eventually creep in. We will become bored and depressed.”[34] Mill claims that gratification from petty pleasures only gives short- term happiness and, subsequently, worsens the individual who may feel that his life lacks happiness, since the happiness is transient. Whereas, intellectual pursuits give long term happiness because provide the individual with constant opportunities throughout the years to improve his life, by benefiting from accruing knowledge. It should be noted that Mill’s views intellectual pursuits as “capable of incorporating the 'finer things' in life” while petty pursuits do not achieve this goal.[35] Mill is saying that intellectual pursuits gives the individual the opportunity to escape the constant depression cycle since these pursuits allow them to achieve their ideals, while petty pleasures do not offer this. Although debate persists about the nature of Mill's view of gratification, this suggests that his was a bifurcated position.

Mill's 'proof' of the principle of utility

In Chapter Four of Utilitarianism, Mill considers what proof can be given for the principle of utility. He says:[36]
The only proof capable of being given that an object is visible, is that people actually see it. The only proof that a sound is audible, is that people hear it... In like manner, I apprehend, the sole evidence it is possible to produce that anything is desirable, is that people do actually desire it… No reason can be given why the general happiness is desirable, except that each person, so far as he believes it to be attainable, desires his own happiness… we have not only all the proof which the case admits of, but all which it is possible to require, that happiness is a good: that each person's happiness is a good to that person, and the general happiness, therefore, a good to the aggregate of all persons.
It is usual[37] to say that Mill is committing a number of fallacies. He is accused of committing the naturalistic fallacy, because he is trying to deduce what people ought to do from what they in fact do; the fallacy of equivocation, because he moves from the fact that (1) something is desirable, i.e. is capable of being desired, to the claim that (2) it is desirable, i.e. that it ought to be desired; and the fallacy of composition, because the fact that people desire their own happiness does not imply that the aggregate of all persons will desire the general happiness.

Such allegations began to emerge in Mill's lifetime, shortly after the publication of Utilitarianism, and persisted for well over a century, though the tide has been turning in recent discussions.

A defence of Mill against all three charges, with a chapter devoted to each, can be found in Necip Fikri Alican's Mill's Principle of Utility: A Defense of John Stuart Mill's Notorious Proof (1994). This is the first, and remains the only, book-length treatment of the subject matter. Yet the alleged fallacies in the proof continue to attract scholarly attention in journal articles and book chapters.

Hall[38] and Popkin[39] defend Mill against this accusation pointing out that he begins Chapter Four by asserting that "questions of ultimate ends do not admit of proof, in the ordinary acceptation of the term" and that this is "common to all first principles." According to Hall and Popkin, therefore, Mill does not attempt to "establish that what people do desire is desirable but merely attempts to make the principles acceptable."[37] The type of "proof" Mill is offering "consists only of some considerations which, Mill thought, might induce an honest and reasonable man to accept utilitarianism."[37]

Having claimed that people do, in fact, desire happiness, Mill now has to show that it is the only thing they desire. Mill anticipates the objection that people desire other things such as virtue. He argues that whilst people might start desiring virtue as a means to happiness, eventually, it becomes part of someone's happiness and is then desired as an end in itself.
The principle of utility does not mean that any given pleasure, as music, for instance, or any given exemption from pain, as for example health, are to be looked upon as means to a collective something termed happiness, and to be desired on that account. They are desired and desirable in and for themselves; besides being means, they are a part of the end. Virtue, according to the utilitarian doctrine, is not naturally and originally part of the end, but it is capable of becoming so; and in those who love it disinterestedly it has become so, and is desired and cherished, not as a means to happiness, but as a part of their happiness.[40]
We may give what explanation we please of this unwillingness; we may attribute it to pride, a name which is given indiscriminately to some of the most and to some of the least estimable feelings of which is mankind are capable; we may refer it to the love of liberty and personal independence, an appeal to which was with the Stoics one of the most effective means for the inculcation of it; to the love of power, or the love of excitement, both of which do really enter into and contribute to it: but its most appropriate appellation is a sense of dignity, which all humans beings possess in one form or other, and in some, though by no means in exact, proportion to their higher faculties, and which is so essential a part of the happiness of those in whom it is strong, that nothing which conflicts with it could be, otherwise than momentarily, an object of desire to them.[41]

Twentieth-century developments

Ideal utilitarianism

The description of ideal utilitarianism was first used by Hastings Rashdall in The Theory of Good and Evil (1907), but it is more often associated with G. E. Moore. In Ethics (1912), Moore rejected a purely hedonistic utilitarianism and argued that there is a range of values that might be maximized. Moore's strategy was to show that it is intuitively implausible that pleasure is the sole measure of what is good. He says that such an assumption:[42]
involves our saying, for instance, that a world in which absolutely nothing except pleasure existed—no knowledge, no love, no enjoyment of beauty, no moral qualities—must yet be intrinsically better—better worth creating—provided only the total quantity of pleasure in it were the least bit greater, than one in which all these things existed as well as pleasure.

It involves our saying that, even if the total quantity of pleasure in each was exactly equal, yet the fact that all the beings in the one possessed in addition knowledge of many different kinds and a full appreciation of all that was beautiful or worthy of love in their world, whereas none of the beings in the other possessed any of these things, would give us no reason whatever for preferring the former to the latter.
Moore admits that it is impossible to prove the case either way, but he believed that it was intuitively obvious that even if the amount of pleasure stayed the same a world that contained such things as beauty and love would be a better world. He adds that, if a person was to take the contrary view, then "I think it is self-evident that he would be wrong."[42]

Act and rule utilitarianism

In the mid-twentieth century a number of philosophers focused on the place of rules in utilitarian thinking.[43] It was already accepted that it is necessary to use rules to help you choose the right action because the problems of calculating the consequences on each and every occasion would almost certainly result in you frequently choosing something less than the best course of action. Paley had justified the use of rules and Mill says:[44]
It is truly a whimsical supposition that, if mankind were agreed in considering utility to be the test of morality, they would remain without any agreement as to what is useful, and would take no measures for having their notions on the subject taught to the young, and enforced by law and opinion… to consider the rules of morality as improvable, is one thing; to pass over the intermediate generalisations entirely, and endeavour to test each individual action directly by the first principle, is another… The proposition that happiness is the end and aim of morality, does not mean that no road ought to be laid down to that goal… Nobody argues that the art of navigation is not founded on astronomy, because sailors cannot wait to calculate the Nautical Almanack. Being rational creatures, they go to sea with it ready calculated; and all rational creatures go out upon the sea of life with their minds made up on the common questions of right and wrong.
However, rule utilitarianism proposes a more central role for rules that was thought to rescue the theory from some of its more devastating criticisms, particularly problems to do with justice and promise keeping. Throughout the 1950s and 1960s, articles were published both for and against the new form of utilitarianism, and through this debate the theory we now call rule utilitarianism was created. In an introduction to an anthology of these articles, the editor was able to say: "The development of this theory was a dialectical process of formulation, criticism, reply and reformulation; the record of this process well illustrates the co-operative development of a philosophical theory."[45]

Smart[46] and McCloskey[47] initially used the terms 'extreme' and 'restricted' utilitarianism but eventually everyone settled on the terms 'act' and 'rule' utilitarianism.

The essential difference is in what determines whether or not an action is the right action. Act utilitarianism maintains that an action is right if it maximizes utility; rule utilitarianism maintains that an action is right if it conforms to a rule that maximizes utility.

In 1956, Urmson published an influential article[48] arguing that Mill justified rules on utilitarian principles. From then on, articles have debated this interpretation of Mill. In all probability, it was not a distinction that Mill was particularly trying to make and so the evidence in his writing is inevitably mixed. A collection of Mill's writing published in 1977 includes a letter in which he says:[49]
I agree with you that the right way of testing actions by their consequences, is to test them by the natural consequences of the particular action, and not by those which would follow if everyone did the same. But, for the most part, the consideration of what would happen if everyone did the same, is the only means we have of discovering the tendency of the act in the particular case.
This seems to tip the balance in favour of saying that Mill is best classified as an act utilitarian.
Some school level textbooks and at least one UK examination board[50] make a further distinction between strong and weak rule utilitarianism. However, it is not clear that this distinction is made in the academic literature.

It has been argued that rule utilitarianism collapses into act utilitarianism, because for any given rule, in the case where breaking the rule produces more utility, the rule can be refined by the addition of a sub-rule that handles cases like the exception.[51] This process holds for all cases of exceptions, and so the "rules" have as many "sub-rules" as there are exceptional cases, which, in the end, makes an agent seek out whatever outcome produces the maximum utility.[52]

Two-level utilitarianism

In Principles (1973),[53] R. M. Hare accepts that rule utilitarianism collapses into act utilitarianism but claims that this is a result of allowing the rules to be "as specific and un-general as we please." He argues that one of the main reasons for introducing rule utilitarianism was to do justice to the general rules that people need for moral education and character development and he proposes that "a difference between act-utilitarianism and rule-utilitarianism can be introduced by limiting the specificity of the rules, i.e., by increasing their generality."[53]:14 This distinction between a "specific rule utilitarianism" (which collapses into act utilitarianism) and "general rule utilitarianism" forms the basis of Hare's two-level utilitarianism.
When we are "playing God or the ideal observer", we use the specific form, and we will need to do this when we are deciding what general principles to teach and follow. When we are "inculcating" or in situations where the biases of our human nature are likely to prevent us doing the calculations properly, then we should use the more general rule utilitarianism.

Hare argues that in practice, most of the time, we should be following the general principles:[53]:17
One ought to abide by the general principles whose general inculcation is for the best; harm is more likely to come, in actual moral situations, from questioning these rules than from sticking to them, unless the situations are very extra-ordinary; the results of sophisticated felicific calculations are not likely, human nature and human ignorance being what they are, to lead to the greatest utility.
In Moral Thinking (1981), Hare illustrated the two extremes. The "archangel" is the hypothetical person who has perfect knowledge of the situation and no personal biases or weaknesses and always uses critical moral thinking to decide the right thing to do; the "prole" is the hypothetical person who is completely incapable of critical thinking and uses nothing but intuitive moral thinking and, of necessity, has to follow the general moral rules they have been taught or learned through imitation.[54] It is not that some people are archangels and others proles, but rather that "we all share the characteristics of both to limited and varying degrees and at different times."[54]

Hare does not specify when we should think more like an "archangel" and more like a "prole" as this will, in any case, vary from person to person. However, the critical moral thinking underpins and informs the more intuitive moral thinking. It is responsible for formulating and, if necessary, reformulating the general moral rules. We also switch to critical thinking when trying to deal with unusual situations or in cases where the intuitive moral rules give conflicting advice.

Preference utilitarianism

The concept of preference utilitarianism was first proposed in 1977 by John Harsanyi in Morality and the theory of rational behaviour,[55] but preference utilitarianism is more commonly associated with R. M. Hare,[54] Peter Singer[56] and Richard Brandt.[57]
Harsanyi claimed that his theory is indebted to Adam Smith, who equated the moral point of view with that of an impartial but sympathetic observer; to Kant, who insisted on the criterion of universality, which may also be described as a criterion of reciprocity; to the classical utilitarians who made maximizing social utility the basic criterion of morality; and to "the modern theory of rational behaviour under risk and uncertainty, usually described as Bayesian decision theory".[55]:42

Harsanyi rejects hedonistic utilitarianism as being dependent on an outdated psychology saying that it is far from obvious that everything we do is motivated by a desire to maximize pleasure and minimize pain. He also rejects ideal utilitarianism because "it is certainly not true as an empirical observation that people's only purpose in life is to have 'mental states of intrinsic worth'."[55]:54

According to Harsanyi, "preference utilitarianism is the only form of utilitarianism consistent with the important philosophical principle of preference autonomy. By this I mean the principle that, in deciding what is good and what is bad for a given individual, the ultimate criterion can only be his own wants and his own preferences."[55]:55

Harsanyi adds two caveats. People sometimes have irrational preferences. To deal with this, Harsanyi distinguishes between "manifest" preferences and "true" preferences. The former are those "manifested by his observed behaviour, including preferences possibly based on erroneous factual beliefs, or on careless logical analysis, or on strong emotions that at the moment greatly hinder rational choice" whereas the latter are "the preferences he would have if he had all the relevant factual information, always reasoned with the greatest possible care, and were in a state of mind most conducive to rational choice."[55]:55 It is the latter that preference utilitarianism tries to satisfy.

The second caveat is that antisocial preferences, such as sadism, envy and resentment, have to be excluded. Harsanyi achieves this by claiming that such preferences partially exclude those people from the moral community:
Utilitarian ethics makes all of us members of the same moral community. A person displaying ill will toward others does remain a member of this community, but not with his whole personality. That part of his personality that harbours these hostile antisocial feelings must be excluded from membership, and has no claim for a hearing when it comes to defining our concept of social utility.[55]:56

More varieties of utilitarianism

Negative utilitarianism

In The Open Society and its Enemies (1945), Karl Popper argued that the principle "maximize pleasure" should be replaced by "minimize pain". He thought "it is not only impossible but very dangerous to attempt to maximize the pleasure or the happiness of the people, since such an attempt must lead to totalitarianism."[58] He claimed that:[59]
there is, from the ethical point of view, no symmetry between suffering and happiness, or between pain and pleasure… In my opinion human suffering makes a direct moral appeal, namely, the appeal for help, while there is no similar call to increase the happiness of a man who is doing well anyway. A further criticism of the Utilitarian formula "Maximize pleasure" is that it assumes a continuous pleasure-pain scale that lets us treat degrees of pain as negative degrees of pleasure. But, from the moral point of view, pain cannot be outweighed by pleasure, and especially not one man's pain by another man's pleasure. Instead of the greatest happiness for the greatest number, one should demand, more modestly, the least amount of avoidable suffering for all...
The actual term negative utilitarianism was introduced by R.N.Smart as the title to his 1958 reply to Popper[60] in which he argued that the principle would entail seeking the quickest and least painful method of killing the entirety of humanity.

Negative total utilitarianism, in contrast, tolerates suffering that can be compensated within the same person.[61][62]

Negative preference utilitarianism avoids the problem of moral killing with reference to existing preferences that such killing would violate, while it still demands a justification for the creation of new lives.[63] A possible justification is the reduction of the average level of preference-frustration.[64]

Others see negative utilitarianism as a branch within modern hedonistic utilitarianism, which assigns a higher weight to the avoidance of suffering than to the promotion of happiness.[65] The moral weight of suffering can be increased by using a "compassionate" utilitarian metric, so that the result is the same as in prioritarianism.[66]

Pessimistic representatives of negative utilitarianism can be found in the environment of Buddhism.[67]

Motive utilitarianism

Motive utilitarianism was first proposed by Robert Merrihew Adams in 1976.[68] Whereas act utilitarianism requires us to choose our actions by calculating which action will maximize utility and rule utilitarianism requires us to implement rules that will, on the whole, maximize utility, motive utilitarianism "has the utility calculus being used to select motives and dispositions according to their general felicific effects, and those motives and dispositions then dictate our choices of actions."[69]

The arguments for moving to some form of motive utilitarianism at the personal level can be seen as mirroring the arguments for moving to some form of rule utilitarianism at the social level.[70] Adams refers to Sidgwick's observation that "Happiness (general as well as individual) is likely to be better attained if the extent to which we set ourselves consciously to aim at it be carefully restricted."[71] Trying to apply the utility calculation on each and every occasion is likely to lead to a sub-optimal outcome. Applying carefully selected rules at the social level and encouraging appropriate motives at the personal level is, so it is argued, likely to lead to a better overall outcome even if on some individual occasions it leads to the wrong action when assessed according to act utilitarian standards.[72]

Adams concludes that "right action, by act-utilitarian standards, and right motivation, by motive-utilitarian standards, are incompatible in some cases."[73] The necessity of this conclusion is rejected by Fred Feldman who argues that "the conflict in question results from an inadequate formulation of the utilitarian doctrines; motives play no essential role in it…(and that)… Precisely the same sort of conflict arises even when MU is left out of consideration and AU is applied by itself."[74] Instead, Feldman proposes a variant of act utilitarianism that results in there being no conflict between it and motive utilitarianism.

Criticisms

Because utilitarianism is not a single theory but a cluster of related theories that have been developed over two hundred years, criticisms can be made for different reasons and have different targets.

Quantifying utility

The main objection to utilitarianism is the inability to quantify, compare, or measure happiness or well-being. Ray Briggs writes in the Stanford Encyclopedia of Philosophy:[75]
One objection to this interpretation of utility is that there may not be a single good (or indeed any good) which rationality requires us to seek. But if we understand “utility” broadly enough to include all potentially desirable ends—pleasure, knowledge, friendship, health and so on—it's not clear that there is a unique correct way to make the tradeoffs between different goods so that each outcome receives a utility. There may be no good answer to the question of whether the life of an ascetic monk contains more or less good than the life of a happy libertine—but assigning utilities to these options forces us to compare them.
Utility understood this way is a personal preference, in the absence of any objective measurement.

Utility ignores justice

As Rosen[22] has pointed out, claiming that act utilitarians are not concerned about having rules is to set up a "straw man". Similarly, Hare refers to "the crude caricature of act utilitarianism which is the only version of it that many philosophers seem to be acquainted with."[76] Given what Bentham says about second order evils[77] it would be a serious misrepresentation to say that he and similar act utilitarians would be prepared to punish an innocent person for the greater good. Nevertheless, whether they would agree or not, this is what critics of utilitarianism claim is entailed by the theory. A classic version of this criticism was given by H. J. McCloskey:[47]
Suppose that a sheriff were faced with the choice either of framing a Negro for a rape that had aroused hostility to the Negroes (a particular Negro generally being believed to be guilty but whom the sheriff knows not to be guilty)—and thus preventing serious anti-Negro riots which would probably lead to some loss of life and increased hatred of each other by whites and Negroes—or of hunting for the guilty person and thereby allowing the anti-Negro riots to occur, while doing the best he can to combat them. In such a case the sheriff, if he were an extreme utilitarian, would appear to be committed to framing the Negro.
By "extreme" utilitarian, McCloskey is referring to what later came to be called "act" utilitarianism. He suggests one response might be that the sheriff would not frame the innocent negro because of another rule: "do not punish an innocent person". Another response might be that the riots the sheriff is trying to avoid might have positive utility in the long run by drawing attention to questions of race and resources to help address tensions between the communities.

In a later article, McCloskey says:[78]
Surely the utilitarian must admit that whatever the facts of the matter may be, it is logically possible that an 'unjust' system of punishment—e.g. a system involving collective punishments, retroactive laws and punishments, or punishments of parents and relations of the offender—may be more useful than a 'just' system of punishment?

Predicting consequences

Some argue that it is impossible to do the calculation that utilitarianism requires because consequences are inherently unknowable. Daniel Dennett describes this as the Three Mile Island effect.[79] Dennett points out that not only is it impossible to assign a precise utility value to the incident, it is impossible to know whether, ultimately, the near-meltdown that occurred was a good or bad thing. He suggests that it would have been a good thing if plant operators learned lessons that prevented future serious incidents.

Russell Hardin rejects such arguments. He argues that it is possible to distinguish the moral impulse of utilitarianism (which is "to define the right as good consequences and to motivate people to achieve these") from our ability to correctly apply rational principles that, among other things, "depend on the perceived facts of the case and on the particular moral actor's mental equipment."[80] The fact that the latter is limited and can change doesn't mean that the former has to be rejected. "If we develop a better system for determining relevant causal relations so that we are able to choose actions that better produce our intended ends, it does not follow that we then must change our ethics. The moral impulse of utilitarianism is constant, but our decisions under it are contingent on our knowledge and scientific understanding."[81]

From the beginning, utilitarianism has recognized that certainty in such matters is unobtainable and both Bentham and Mill said that it was necessary to rely on the tendencies of actions to bring about consequences. G. E. Moore, writing in 1903, said:[82]
We certainly cannot hope directly to compare their effects except within a limited future; and all the arguments, which have ever been used in Ethics, and upon which we commonly act in common life, directed to shewing that one course is superior to another, are (apart from theological dogmas) confined to pointing out such probable immediate advantages…

An ethical law has the nature not of a scientific law but of a scientific prediction: and the latter is always merely probable, although the probability may be very great.

Demandingness objection

Act utilitarianism not only requires everyone to do what they can to maximize utility, but to do so without any favouritism. Mill said, "As between his own happiness and that of others, utilitarianism requires him to be as strictly impartial as a disinterested and benevolent spectator."[83] Critics say that this combination of requirements leads to utilitarianism making unreasonable demands. The well-being of strangers counts just as much as that of friends, family or self. "What makes this requirement so demanding is the gargantuan number of strangers in great need of help and the indefinitely many opportunities to make sacrifices to help them."[84] As Shelly Kagan says, "Given the parameters of the actual world, there is no question that …(maximally)… promoting the good would require a life of hardship, self-denial, and austerity…a life spent promoting the good would be a severe one indeed."[85]

Hooker describes two aspects to the problem: act utilitarianism requires huge sacrifices from those who are relatively better off and also requires sacrifice of your own good even when the aggregate good will be only slightly increased.[86] Another way of highlighting the complaint is to say that in utilitarianism, "there is no such thing as morally permissible self-sacrifice that goes above and beyond the call of duty."[86] Mill was quite clear about this, "A sacrifice which does not increase, or tend to increase, the sum total of happiness, it considers as wasted."[83]

One response to the problem is to accept its demands. This is the view taken by Peter Singer, who says: "No doubt we do instinctively prefer to help those who are close to us. Few could stand by and watch a child drown; many can ignore the avoidable deaths of children in Africa or India. The question, however, is not what we usually do, but what we ought to do, and it is difficult to see any sound moral justification for the view that distance, or community membership, makes a crucial difference to our obligations."[87]

Others argue that a moral theory that is so contrary to our deeply held moral convictions must either be rejected or modified.[88] There have been various attempts to modify utilitarianism to escape its seemingly over-demanding requirements.[89] One approach is to drop the demand that utility be maximized. In Satisficing Consequentialism, Michael Slote argues for a form of utilitarianism where "an act might qualify as morally right through having good enough consequences, even though better consequences could have been produced."[90] One advantage of such a system is that it would be able to accommodate the notion of supererogatory actions.

Samuel Scheffler takes a different approach and amends the requirement that everyone be treated the same.[91] In particular, Scheffler suggests that there is an "agent-centered prerogative" such that when the overall utility is being calculated it is permitted to count our own interests more heavily than the interests of others. Kagan suggests that such a procedure might be justified on the grounds that "a general requirement to promote the good would lack the motivational underpinning necessary for genuine moral requirements" and, secondly, that personal independence is necessary for the existence of commitments and close personal relations and that "the value of such commitments yields a positive reason for preserving within moral theory at least some moral independence for the personal point of view."[92]

Robert Goodin takes yet another approach and argues that the demandingness objection can be "blunted" by treating utilitarianism as a guide to public policy rather than one of individual morality. He suggests that many of the problems arise under the traditional formulation because the conscientious utilitarian ends up having to make up for the failings of others and so contributing more than their fair share.[93]

Harsanyi argues that the objection overlooks the fact that "people attach considerable utility to freedom from unduly burdensome moral obligations… most people will prefer a society with a more relaxed moral code, and will feel that such a society will achieve a higher level of average utility—even if adoption of such a moral code should lead to some losses in economic and cultural accomplishments (so long as these losses remain within tolerable limits). This means that utilitarianism, if correctly interpreted, will yield a moral code with a standard of acceptable conduct very much below the level of highest moral perfection, leaving plenty of scope for supererogatory actions exceeding this minimum standard."[94]

Aggregating utility

The objection that "utilitarianism does not take seriously the distinction between persons"[95] came to prominence in 1971 with the publication of John Rawls' A Theory of Justice. The concept is also important in animal rights advocate Richard Ryder's rejection of utilitarianism, in which he talks of the "boundary of the individual", through which neither pain nor pleasure may pass.[96] However, a similar objection was noted in 1970 by Thomas Nagel (who claimed that consequentialism "treats the desires, needs, satisfactions, and dissatisfactions of distinct persons as if they were the desires, etc., of a mass person"[97]), and even earlier by David Gauthier, who wrote that utilitarianism supposes "that mankind is a super-person, whose greatest satisfaction is the objective of moral action. . . . But this is absurd. Individuals have wants, not mankind; individuals seek satisfaction, not mankind. A person's satisfaction is not part of any greater satisfaction."[98] Thus, the aggregation of utility becomes futile as both pain and happiness are intrinsic to and inseparable from the consciousness in which they are felt, rendering impossible the task of adding up the various pleasures of multiple individuals.

A response to this criticism is to point out that whilst seeming to resolve some problems it introduces others. Intuitively, there are many cases where people do want to take the numbers involved into account. As Alastair Norcross has said, "suppose that Homer is faced with the painful choice between saving Barney from a burning building or saving both Moe and Apu from the building…it is clearly better for Homer to save the larger number, precisely because it is a larger number… Can anyone who really considers the matter seriously honestly claim to believe that it is worse that one person die than that the entire sentient population of the universe be severely mutilated? Clearly not."[99]

It may be possible to uphold the distinction between persons whilst still aggregating utility, if it accepted that people can be influenced by empathy.[100] This position is advocated by Iain King,[101] who has suggested the evolutionary basis of empathy means humans can take into account the interests of other individuals, but only on a one-to-one basis, "since we can only imagine ourselves in the mind of one other person at a time."[102] King uses this insight to adapt utilitarianism, and it may help reconcile Bentham's philosophy with deontology and virtue ethics.[103]

The philosopher John Taurek also argued that the idea of adding happiness or pleasures across persons is quite unintelligible and that the numbers of persons involved in a situation are morally irrelevant.[104] Taurek's basic concern comes down to this: we cannot explain what it means to say that things would be five times worse if five people die than if one person dies. "I cannot give a satisfactory account of the meaning of judgments of this kind," he wrote (p. 304). He argues that each person can only lose one person's happiness or pleasures. There isn't five times more loss of happiness or pleasure when five die: who would be feeling this happiness or pleasure? "Each person's potential loss has the same significance to me, only as a loss to that person alone. because, by hypothesis, I have an equal concern for each person involved, I am moved to give each of them an equal chance to be spared his loss" (p. 307). Parfit[105] and others[106] have criticized Taurek's line, and it continues to be discussed.[107]

Calculating utility is self-defeating

An early criticism, which was addressed by Mill, is that if time is taken to calculate the best course of action it is likely that the opportunity to take the best course of action will already have passed. Mill responded that there had been ample time to calculate the likely effects:[83]
...namely, the whole past duration of the human species. During all that time, mankind have been learning by experience the tendencies of actions; on which experience all the prudence, as well as all the morality of life, are dependent…It is a strange notion that the acknowledgment of a first principle is inconsistent with the admission of secondary ones. To inform a traveller respecting the place of his ultimate destination, is not to forbid the use of landmarks and direction-posts on the way. The proposition that happiness is the end and aim of morality, does not mean that no road ought to be laid down to that goal, or that persons going thither should not be advised to take one direction rather than another. Men really ought to leave off talking a kind of nonsense on this subject, which they would neither talk nor listen to on other matters of practical concernment.
More recently, Hardin has made the same point. "It should embarrass philosophers that they have ever taken this objection seriously. Parallel considerations in other realms are dismissed with eminently good sense. Lord Devlin notes, 'if the reasonable man "worked to rule" by perusing to the point of comprehension every form he was handed, the commercial and administrative life of the country would creep to a standstill.'"[81]

It is such considerations that lead even act utilitarians to rely on "rules of thumb", as Smart[108] has called them.

Karl Marx's criticism

Karl Marx, in Das Kapital, criticises Bentham's utilitarianism on the grounds that it does not appear to recognise that different people have different joys:[109]
Not even excepting our philosopher, Christian Wolff, in no time and in no country has the most homespun commonplace ever strutted about in so self-satisfied a way. The principle of utility was no discovery of Bentham. He simply reproduced in his dull way what Helvétius and other Frenchmen had said with esprit in the 18th century. To know what is useful for a dog, one must study dog-nature. This nature itself is not to be deduced from the principle of utility. Applying this to man, he who would criticize all human acts, movements, relations, etc., by the principle of utility, must first deal with human nature in general, and then with human nature as modified in each historical epoch. Bentham makes short work of it. With the driest naivete he takes the modern shopkeeper, especially the English shopkeeper, as the normal man. Whatever is useful to this queer normal man, and to his world, is absolutely useful. This yard-measure, then, he applies to past, present, and future. The Christian religion, e.g., is "useful," "because it forbids in the name of religion the same faults that the penal code condemns in the name of the law." Artistic criticism is "harmful," because it disturbs worthy people in their enjoyment of Martin Tupper, etc. With such rubbish has the brave fellow, with his motto, "nulla dies sine linea [no day without a line]", piled up mountains of books.

John Paul II's personalist criticism

Pope John Paul II, following his personalist philosophy, argued that a danger of utilitarianism is that it tends to make persons, just as much as things, the object of use. "Utilitarianism," he wrote, "is a civilization of production and of use, a civilization of things and not of persons, a civilization in which persons are used in the same way as things are used."[110]

Additional considerations

Average v. total happiness

In The Methods of Ethics, Henry Sidgwick asked, "Is it total or average happiness that we seek to make a maximum?"[111] He noted that aspects of the question had been overlooked and answered the question himself by saying that what had to be maximized was the average multiplied by the number of people living.[112] He also argued that, if the "average happiness enjoyed remains undiminished, Utilitarianism directs us to make the number enjoying it as great as possible."[112] This was also the view taken earlier by Paley. He notes that, although he speaks of the happiness of communities, "the happiness of a people is made up of the happiness of single persons; and the quantity of happiness can only be augmented by increasing the number of the percipients, or the pleasure of their perceptions" and that if extreme cases, such as people held as slaves, are excluded the amount of happiness will usually be in proportion to the number of people. Consequently, "the decay of population is the greatest evil that a state can suffer; and the improvement of it the object which ought, in all countries, to be aimed at in preference to every other political purpose whatsoever."[113] A similar view was expressed by Smart, who argued that all other things being equal a universe with two million happy people is better than a universe with only one million happy people.[114]

Since Sidgwick raised the question it has been studied in detail and philosophers have argued that using either total or average happiness can lead to objectionable results.

According to Derek Parfit, using total happiness falls victim to the repugnant conclusion, whereby large numbers of people with very low but non-negative utility values can be seen as a better goal than a population of a less extreme size living in comfort. In other words, according to the theory, it is a moral good to breed more people on the world for as long as total happiness rises.[115]

On the other hand, measuring the utility of a population based on the average utility of that population avoids Parfit's repugnant conclusion but causes other problems. For example, bringing a moderately happy person into a very happy world would be seen as an immoral act; aside from this, the theory implies that it would be a moral good to eliminate all people whose happiness is below average, as this would raise the average happiness.[116]

William Shaw suggests that the problem can be avoided if a distinction is made between potential people, who need not concern us, and actual future people, who should concern us. He says, "utilitarianism values the happiness of people, not the production of units of happiness. Accordingly, one has no positive obligation to have children. However, if you have decided to have a child, then you have an obligation to give birth to the happiest child you can."[117]

Motives, intentions, and actions

Utilitarianism is typically taken to assess the rightness or wrongness of an action by considering just the consequences of that action. Bentham very carefully distinguishes motive from intention and says that motives are not in themselves good or bad but can be referred to as such on account of their tendency to produce pleasure or pain. He adds that, "from every kind of motive, may proceed actions that are good, others that are bad, and others that are indifferent."[118] Mill makes a similar point[119] and explicitly says that "motive has nothing to do with the morality of the action, though much with the worth of the agent. He who saves a fellow creature from drowning does what is morally right, whether his motive be duty, or the hope of being paid for his trouble."[120]

However, with intention the situation is more complex. In a footnote printed in the second edition of Utilitarianism, Mill says: "the morality of the action depends entirely upon the intention—that is, upon what the agent wills to do."[120] Elsewhere, he says, "Intention, and motive, are two very different things. But it is the intention, that is, the foresight of consequences, which constitutes the moral rightness or wrongness of the act."[121]

The correct interpretation of Mill's footnote is a matter of some debate. The difficulty in interpretation centres around trying to explain why, since it is consequences that matter, intentions should play a role in the assessment of the morality of an action but motives should not. One possibility "involves supposing that the 'morality' of the act is one thing, probably to do with the praiseworthiness or blameworthiness of the agent, and its rightness or wrongness another."[122] Jonathan Dancy rejects this interpretation on the grounds that Mill is explicitly making intention relevant to an assessment of the act not to an assessment of the agent.

An interpretation given by Roger Crisp draws on a definition given by Mill in A System of Logic, where he says that an "intention to produce the effect, is one thing; the effect produced in consequence of the intention, is another thing; the two together constitute the action."[123] Accordingly, whilst two actions may outwardly appear to be the same they will be different actions if there is a different intention. Dancy notes that this does not explain why intentions count but motives do not.

A third interpretation is that an action might be considered a complex action consisting of several stages and it is the intention that determines which of these stages are to be considered part of the action. Although this is the interpretation favoured by Dancy, he recognizes that this might not have been Mill's own view, for Mill "would not even allow that 'p & q' expresses a complex proposition. He wrote in his System of Logic I iv. 3, of 'Caesar is dead and Brutus is alive', that 'we might as well call a street a complex house, as these two propositions a complex proposition'."[122]

Finally, whilst motives may not play a role in determining the morality of an action, this does not preclude utilitarians from fostering particular motives if doing so will increase overall happiness.

Humans alone, or other sentient beings?

Nonhuman animals


In An Introduction to the Principles of Morals and Legislation Bentham wrote "the question is not, Can they reason? nor, Can they talk? but, Can they suffer?"[124] Mill's distinction between higher and lower pleasures might suggest that he gave more status to humans but in The Methods of Ethics, philosopher Henry Sidgwick says "We have next to consider who the 'all' are, whose happiness is to be taken into account. Are we to extend our concern to all the beings capable of pleasure and pain whose feelings are affected by our conduct? or are we to confine our view to human happiness? The former view is the one adopted by Bentham and Mill, and (I believe) by the Utilitarian school generally: and is obviously most in accordance with the universality that is characteristic of their principle ... it seems arbitrary and unreasonable to exclude from the end, as so conceived, any pleasure of any sentient being."[125]

Moreover, John Stuart Mill himself, in Whewell on Moral Philosophy, defends Bentham's advocacy for animal rights, calling it a 'noble anticipation', and writing: "Granted that any practice causes more pain to animals than it gives pleasure to man; is that practice moral or immoral? And if, exactly in proportion as human beings raise their heads out of the slough of selfishness, they do not with one voice answer 'immoral', let the morality of the principle of utility be for ever condemned."[126]

The utilitarian philosopher Peter Singer and many other animal rights activists have continued to argue that the well-being of all sentient beings ought to be seriously considered. Singer suggests that rights are conferred according to the level of a creature's self-awareness, regardless of their species. He adds that humans tend to be speciesist (discriminatory against non-humans) in ethical matters, and argues that, on utilitarianism, speciesism cannot be justified as there is no rational distinction that can be made between the suffering of humans and the suffering of nonhuman animals; all suffering ought to be reduced. Singer writes: "The racist violates the principle of equality by giving greater weight to the interests of members of his own race, when there is a clash between their interests and the interests of those of another race. Similarly the speciesist allows the interests of his own species to override the greater interests of members of other species. The pattern is the same in each case ... Most human beings are speciesists."[127]

In his 1990 edition of Animal Liberation, Peter Singer said that he no longer ate oysters and mussels, because although the creatures might not suffer, they might, it's not really known, and it's easy enough to avoid eating them in any case[128] (and this aspect of seeking better alternatives is a prominent part of utilitarianism).

This view still might be contrasted with deep ecology, which holds that an intrinsic value is attached to all forms of life and nature, whether currently assumed to be sentient or not. According to utilitarianism, the forms of life that are unable to experience anything akin to either enjoyment or discomfort are denied moral status, because it is impossible to increase the happiness or reduce the suffering of something that cannot feel happiness or suffer. Singer writes:
The capacity for suffering and enjoying things is a prerequisite for having interests at all, a condition that must be satisfied before we can speak of interests in any meaningful way. It would be nonsense to say that it was not in the interests of a stone to be kicked along the road by a schoolboy. A stone does not have interests because it cannot suffer. Nothing that we can do to it could possibly make any difference to its welfare. A mouse, on the other hand, does have an interest in not being tormented, because it will suffer if it is. If a being suffers, there can be no moral justification for refusing to take that suffering into consideration. No matter what the nature of the being, the principle of equality requires that its suffering be counted equally with the like suffering—in so far as rough comparisons can be made—of any other being. If a being is not capable of suffering, or of experiencing enjoyment or happiness, there is nothing to be taken into account.
Thus, the moral value of one-celled organisms, as well as some multi-cellular organisms, and natural entities like a river, is only in the benefit they provide to sentient beings. Similarly, utilitarianism places no direct intrinsic value on biodiversity, although the benefits that biodiversity bring to sentient beings may mean that, on utilitarianism, biodiversity ought to be maintained in general.

In John Stuart Mill's essay "On Nature"[129] he argues that the welfare of wild animals is to be considered when making utilitarian judgments. Tyler Cowen argues that, if individual animals are carriers of utility, then we should consider limiting the predatory activity of carnivores relative to their victims: "At the very least, we should limit current subsidies to nature's carnivores."[130]

Application to specific issues

World poverty

An article in the American journal for Economics has addressed the issue of Utilitarian ethics within redistribution of wealth. The journal stated that taxation of the wealthy is the best way to make use of the disposable income they receive. This says that the money creates utility for the most people by funding government services.[131] Many utilitarian philosophers, including Peter Singer and Toby Ord, argue that inhabitants of developed countries in particular have an obligation to help to end extreme poverty across the world, for example by regularly donating some of their income to charity. Peter Singer, for example, argues that donating some of one's income to charity could help to save a life or cure somebody from a poverty-related illness, which is a much better use of the money as it brings someone in extreme poverty far more happiness than it would bring to oneself if one lived in relative comfort. However, Singer not only argues that one ought to donate a significant proportion of one's income to charity, but also that this money should be directed to the most cost-effective charities, in order to bring about the greatest good for the greatest number, consistent with utilitarian thinking.[132] Singer's ideas have formed the basis of the modern effective altruist movement.
