Psychological egoism

From Wikipedia, the free encyclopedia
https://en.wikipedia.org/wiki/Psychological_egoism

Psychological egoism is the view that humans are always motivated by self-interest and selfishness, even in what seem to be acts of altruism. It claims that, when people choose to help others, they do so ultimately because of the personal benefits that they themselves expect to obtain, directly or indirectly, from so doing. This is a descriptive rather than normative view, since it only makes claims about how things are, not how they ought to be. It is, however, related to several other normative forms of egoism, such as ethical egoism and rational egoism.

A specific form of psychological egoism is psychological hedonism, the view that the ultimate motive for all voluntary human action is the desire to experience pleasure or to avoid pain. Many discussions of psychological egoism focus on this type, but the two are not the same: theorists have explained behavior motivated by self-interest without using pleasure and pain as the final causes of behavior. Psychological hedonism argues actions are caused by both a need for pleasure immediately and in the future. However, immediate gratification can be sacrificed for a chance of greater, future pleasure. Further, humans are not motivated to strictly avoid pain and only pursue pleasure, but, instead, humans will endure pain to achieve the greatest net pleasure. Accordingly, all actions are tools for increasing pleasure or decreasing pain, even those defined as altruistic and those that do not cause an immediate change in satisfaction levels.

Foundations

Beginning with ancient philosophy, Epicureanism claims humans live to maximize pleasure. Epicurus argued the theory of human behavior being motivated by pleasure alone is evidenced from infancy to adulthood. Humanity performs altruistic, honorable, and virtuous acts not for the sake of another or because of a moral code but rather to increase the well being of the self.

In modern philosophy, Jeremy Bentham asserted, like Epicurus, that human behavior is governed by a need to increase pleasure and decrease pain. Bentham explicitly described what types and qualities of pain and pleasure exist, and how human motives are singularly explained using psychological hedonism. Bentham attempted to quantify psychological hedonism. Bentham endeavored to find the ideal human behavior based on hedonic calculus or the measurement of relative gains and losses in pain and pleasure to determine the most pleasurable action a human could choose in a situation.

From an evolutionary perspective, Herbert Spencer, a psychological egoist, argued that all animals primarily seek to survive and protect their lineage. Essentially, the need for the individual and for the individual's immediate family to live supersedes the others' need to live. All species attempt to maximize their own chances of survival and, therefore, well being. Spencer asserted the best adapted creatures will have their pleasure levels outweigh their pain levels in their environments. Thus, pleasure meant an animal was fulfilling its egoist goal of self survival, and pleasure would always be pursued because species constantly strive for survival.

Contributions to modern psychology


Psychoanalysis

Whether or not Sigmund Freud was a psychological egoist, his concept of the pleasure principle borrowed much from psychological egoism and psychological hedonism in particular. The pleasure principle rules the behavior of the Id which is an unconscious force driving humans to release tension from unfulfilled desires. When Freud introduced Thanatos and its opposing force, Eros, the pleasure principle emanating from psychological hedonism became aligned with the Eros, which drives a person to satiate sexual and reproductive desires. Alternatively, Thanatos seeks the cessation of pain through death and the end of the pursuit of pleasure: thus a hedonism rules Thanatos, but it centers on the complete avoidance of pain rather than psychological hedonist function which pursues pleasure and avoids pain. Therefore, Freud believed in qualitatively different hedonisms where the total avoidance of pain hedonism and the achievement of the greatest net pleasure hedonism are separate and associated with distinct functions and drives of the human psyche. Although Eros and Thanatos are ruled by qualitatively different types of hedonism, Eros remains under the rule of Jeremy Bentham's quantitative psychological hedonism because Eros seeks the greatest net pleasure.

Behaviorism

Traditional behaviorism dictates all human behavior is explained by classical conditioning and operant conditioning. Operant conditioning works through reinforcement and punishment which adds or removes pleasure and pain to manipulate behavior. Using pleasure and pain to control behavior means behaviorists assumed the principles of psychological hedonism could be applied to predicting human behavior. For example, Thorndike's law of effect states that behaviors associated with pleasantness will be learned and those associated with pain will be extinguished. Often, behaviorist experiments using humans and animals are built around the assumption that subjects will pursue pleasure and avoid pain. Although psychological hedonism is incorporated into the fundamental principles and experimental designs of behaviorism, behaviorism itself explains and interprets only observable behavior and therefore does not theorize about the ultimate cause of human behavior. Thus, behaviorism uses but does not strictly support psychological hedonism over other understandings of the ultimate drive of human behavior.

Debate

Psychological egoism is controversial. Proponents cite evidence from introspection: reflection on one's own actions may reveal their motives and intended results to be based on self-interest. Psychological egoists and hedonists have found through numerous observations of natural human behavior that behavior can be manipulated through reward and punishment both of which have direct effects of pain and pleasure. Also, the work of some social scientists has empirically supported this theory. Further, they claim psychological egoism posits a theory that is a more parsimonious explanation than competing theories.

Opponents have argued that psychological egoism is not more parsimonious than other theories. For example, a theory that claims altruism occurs for the sake of altruism explains altruism with less complexity than the egoistic approach. The psychological egoist asserts humans act altruistically for selfish reasons even when cost of the altruistic action is far outweighed by the reward of acting selfishly because altruism is performed to fulfill the desire of a person to act altruistically. Other critics argue that it is false either because it is an over-simplified interpretation of behavior or that there exists empirical evidence of altruistic behaviour. Recently, some have argued that evolutionary theory provides evidence against it.

Critics have stated that proponents of psychological egoism often confuse the satisfaction of their own desires with the satisfaction of their own self-regarding desires. Even though it is true that every human being seeks his own satisfaction, this sometimes may only be achieved via the well-being of his neighbor. An example of this situation could be phoning for an ambulance when a car accident has happened. In this case, the caller desires the well-being of the victim, even though the desire itself is the caller's own.

To counter this critique, psychological egoism asserts that all such desires for the well being of others are ultimately derived from self-interest. For example, German philosopher Friedrich Nietzsche was a psychological egoist for some of his career, though he is said to have repudiated that later in his campaign against morality. He argues in §133 of The Dawn, that in such cases compassionate impulses arise out of the projection of our identity unto the object of our feeling. He gives some hypothetical examples as illustrations to his thesis: that of a person, feeling horrified after witnessing a personal feud, coughing blood, or that of the impulse felt to save a person who is drowning in the water. In such cases, according to Nietzsche, there comes into play unconscious fears regarding our own safety. The suffering of another person is felt as a threat to our own happiness and sense of safety, because it reveals our own vulnerability to misfortunes, and thus, by relieving it, one could also ameliorate those personal sentiments. Essentially, proponents argue that altruism is rooted in self-interest whereas opponents claim altruism occurs for altruism's sake or is caused by a non-selfish reason.

Problem of apparent altruism

David Hume once wrote, "What interest can a fond mother have in view, who loses her health by assiduous attendance on her sick child, and afterwards languishes and dies of grief, when freed, by its death [the child's], from the slavery of that attendance?". It seems incorrect to describe such a mother's goal as self-interested.

Psychological egoists, however, respond that helping others in such ways is ultimately motivated by some form of self-interest, such as non-sensory satisfaction, the expectation of reciprocation, the desire to gain respect or reputation, or by the expectation of a reward in a putative afterlife. The helpful action is merely instrumental to these ultimately selfish goals.

In the ninth century, Mohammed Ibn Al-Jahm Al-Barmaki (محمد بن الجـَهْم البَرمَكي) has been quoted saying:
"No one deserves thanks from another about something he has done for him or goodness he has done, he is either willing to get a reward from God, therefore he wanted to serve himself, or he wanted to get a reward from people, therefore, he has done that to get profit for himself, or to be mentioned and praised by people, therefore, to it is also for himself, or due to his mercy and tenderheartedness, so he has simply done that goodness to pacify these feelings and treat himself."
This sort of explanation appears to be close to the view of La Rochefoucauld (and perhaps Hobbes).

According to psychological hedonism, the ultimate egoistic motive is to gain good feelings of pleasure and avoid bad feelings of pain. Other, less restricted forms of psychological egoism may allow the ultimate goal of a person to include such things as avoiding punishments from oneself or others (such as guilt or shame) and attaining rewards (such as pride, self-worth, power or reciprocal beneficial action).

Some psychologists explain empathy in terms of psychological hedonism. According to the "merge with others hypothesis", empathy increases the more an individual feels like they are one with another person, and decreases as the oneness decreases. Therefore, altruistic actions emanating from empathy and empathy itself are caused by making others' interests our own, and the satisfaction of their desires becomes our own, not just theirs. Both cognitive studies and neuropsychological experiments have provided evidence for this theory: as humans increase our oneness with others our empathy increases, and as empathy increases our inclination to act altruistically increases. Neuropsychological studies have linked mirror neurons to humans experiencing empathy. Mirror neurons are activated both when a human (or animal) performs an action and when they observe another human (or animal) performs the same action. Researchers have found that the more these mirror neurons fire the more human subjects report empathy. From a neurological perspective, scientists argue that when a human empathizes with another, the brain operates as if the human is actually participating in the actions of the other person. Thus, when performing altruistic actions motivated by empathy, humans experience someone else's pleasure of being helped. Therefore, in performing acts of altruism, people act in their own self interests even at a neurological level.

Criticism


Explanatory power

Even accepting the theory of universal positivity, it is difficult to explain, for example, the actions of a soldier who sacrifices his life by jumping on a grenade in order to save his comrades. In this case, there is simply no time to experience positivity toward one's actions, although a psychological egoist may argue that the soldier experiences moral positivity in knowing that he is sacrificing his life to ensure the survival of his comrades, or that he is avoiding negativity associated with the thought of all his comrades dying. Psychological egoists argue that although some actions may not clearly cause physical nor social positivity, nor avoid negativity, one's current contemplation or reactionary mental expectation of these is the main factor of the decision. When a dog is first taught to sit, it is given a biscuit. This is repeated until, finally, the dog sits without requiring a biscuit. Psychological egoists could claim that such actions which do not 'directly' result in positivity, or reward, are not dissimilar from the actions of the dog. In this case, the action (sitting on command) will have become a force of habit, and breaking such a habit would result in mental discomfort. This basic theory of conditioning behaviour, applied to other seemingly ineffective positive actions, can be used to explain moral responses that are instantaneous and instinctive such as the soldier jumping on the grenade.

Circularity

Psychological egoism has been accused of being circular: "If a person willingly performs an act, that means he derives personal enjoyment from it; therefore, people only perform acts that give them personal enjoyment." In particular, seemingly altruistic acts must be performed because people derive enjoyment from them and are therefore, in reality, egoistic. This statement is circular because its conclusion is identical to its hypothesis: it assumes that people only perform acts that give them personal enjoyment, and concludes that people only perform acts that give them personal enjoyment. This objection was tendered by William Hazlitt and Thomas Macaulay in the 19th century, and has been restated many times since. An earlier version of the same objection was made by Joseph Butler in 1726.

Joel Feinberg, in his 1958 paper "Psychological Egoism", embraces a similar critique by drawing attention to the infinite regress of psychological egoism. He expounds it in the following cross-examination:
"All men desire only satisfaction."
"Satisfaction of what?"
"Satisfaction of their desires."
"Their desires for what?"
"Their desires for satisfaction."
"Satisfaction of what?"
"Their desires."
"For what?"
"For satisfaction"—etc., ad infinitum.
 

Evolutionary argument

In their 1998 book, Unto Others, Sober and Wilson detailed an evolutionary argument based on the likelihood for egoism to evolve under the pressures of natural selection. Specifically, they focus on the human behavior of parental care. To set up their argument, they propose two potential psychological mechanisms for this. The hedonistic mechanism is based on a parent's ultimate desire for pleasure or the avoidance of pain and a belief that caring for its offspring will be instrumental to that. The altruistic mechanism is based on an altruistic ultimate desire to care for its offspring.

Sober and Wilson argue that when evaluating the likelihood of a given trait to evolve, three factors must be considered: availability, reliability and energetic efficiency. The genes for a given trait must first be available in the gene pool for selection. The trait must then reliably produce an increase in fitness for the organism. The trait must also operate with energetic efficiency to not limit the fitness of the organism. Sober and Wilson argue that there is neither reason to suppose that an altruistic mechanism should be any less available than a hedonistic one nor reason to suppose that the content of thoughts and desires (hedonistic vs. altruistic) should impact energetic efficiency. As availability and energetic efficiency are taken to be equivalent for both mechanisms it follows that the more reliable mechanism will then be the more likely mechanism.

For the hedonistic mechanism to produce the behavior of caring for offspring, the parent must believe that the caring behavior will produce pleasure or avoidance of pain for the parent. Sober and Wilson argue that the belief also must be true and constantly reinforced, or it would not be likely enough to persist. If the belief fails then the behavior is not produced. The altruistic mechanism does not rely on belief; therefore, they argue that it would be less likely to fail than the alternative, i.e. more reliable

Hedonism

From Wikipedia, the free encyclopedia
 
Hedonism is a school of thought that argues seeking pleasure and avoiding suffering are the only components of well-being. Ethical hedonism is the view that combines hedonism with welfarist ethics, which claim that what we should do depends exclusively on what affects the well-being individuals have. Ethical hedonists would defend either increasing pleasure and reducing suffering for all beings capable of experiencing them, or just reducing suffering in the case of negative consequentialism. According to negative utilitarianism, only the minimization of suffering would matter. 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.

For its part, hedonistic ethical egoism 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.

Etymology and lexicon

The name derives from the Greek word for "delight" (ἡδονισμός hēdonismos from ἡδονή hēdonē "pleasure", cognate via Proto-Indo-European swéh₂dus through Ancient Greek ἡδύς with English sweet + suffix -ισμός -ismos "ism").

Opposite to hedonism, there is hedonophobia. This is an extremely strong aversion to hedonism. According to medical author William C. Shiel Jr., MD, FACP, FACR, hedonophobia is "an abnormal, excessive, and persistent fear of pleasure."

The condition of being unable to experience pleasure is anhedonia.

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.

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.
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).

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. Theodorus the Atheist was a latter exponent of hedonism who was a disciple of younger Aristippus, 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. They thought that we can know with certainty our immediate sense-experiences (for instance, that one is having a sweet sensation) but can know nothing about the nature of the objects that cause these sensations (for instance, that the honey is sweet). They also denied that we can have knowledge of what the experiences of other people are like. 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. 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. 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. 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. 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. 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. Likewise, friendship and justice are useful because of the pleasure they provide. 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"), and it is impossible to live wisely and well and justly without living a pleasant life.
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 the world was created to serve God, and in order to do so properly, God in turn gives mankind the opportunity to experience pleasure in the process of serving Him. (Talmud Kidushin 82:b) 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. The Book of Ecclesiastes in the Old Testament proclaims, "There is nothing better for a person than that he should eat and drink and find enjoyment in his toil. This also, I saw, is from the hand of God..." (Ecclesiastes 2:24) 

Christianity

Ethical hedonism as part of Christian theology has also been a concept in some evangelical circles, particularly in those of the Reformed tradition. 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.”  Piper states his term may describe the theology of Jonathan Edwards, who in 1812 referred to "a future enjoyment of Him [God] in heaven". 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 Nastika (heterodox) philosophy such as the Charvaka school. However, Hedonism is criticized by Astika (orthodox) schools of thought on the basis that it is inherently egoistic and therefore detrimental to spiritual liberation.

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. 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. 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:
  • 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 and John Wilmot. 

Contemporary approaches

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

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 and La puissance d'exister : Manifeste hédoniste). He defines hedonism "as an introspective attitude to life based on taking pleasure yourself and pleasuring others, without harming yourself or anyone else". 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."

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," 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". 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".

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 utilitarianism. David 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 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". A transhumanist and a vegan, 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 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.

Dan Haybron

Haybron has distinguished between psychological, ethical, welfare and axiological hedonism.

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. 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). 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, they can become on average 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.

Criticism

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.

Perhaps the most famous objection to hedonism is Robert Nozick's famous experience machine. Nozick asks us to hypothetically imagine a machine that will allow us to experience whatever we want—if we want to experience making friends, it will give this to us. Nozick claims that by hedonistic logic, we should remain in this machine for the rest of our lives. However, he gives three reasons why this is not a preferable scenario: firstly, because we want to do certain things, as opposed to merely experience them; secondly, we want to be a certain kind of person, as opposed to an 'indeterminate blob' and thirdly, because such a thing would limit our experiences to only what we can imagine. Peter Singer, a hedonistic utilitarian, and Katarzyna de Lazari-Radek have both argued against such an objection by saying that it only provides an answer to certain forms of hedonism, and ignores others.

Islamic criticisms

In Islam, one of the main duties of a Muslim is to conquer his nafs (his ego, self, passions, desires) and to be free from it. Certain joys of life are permissible provided they do not lead to excess or evildoing that may bring harm. It is understood that everyone takes their passion as their idol, Islam calls these tawaghit (idols) and Taghut (worship of other than Allah) so there has to be a means of controlling these nafs.
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.

Anhedonia is a diverse array of deficits in hedonic function, including reduced motivation or ability to experience pleasure. While earlier definitions of anhedonia emphasized the inability to experience pleasure, anhedonia is used by researchers to refer to reduced motivation, reduced anticipatory pleasure (wanting), reduced consummatory pleasure (liking), and deficits in reinforcement learning. In the DSM-5, anhedonia is a component of depressive disorders, substance related disorders, psychotic disorders, and personality disorders, where it is defined by either a reduced ability to experience pleasure, or a diminished interest in engaging in pleasurable activities. While the ICD-10 does not explicitly mention anhedonia, the depressive symptom analogous to anhedonia as described in the DSM-V is a loss of interest or pleasure.

Definition

While anhedonia was originally defined in 1896 by Théodule-Armand Ribot as the reduced ability to experience pleasure, it has been used to refer to deficits in multiple facets of reward. Re-conceptualizations of anhedonia highlight the independence of "wanting" and "liking". "Wanting" is a component of anticipatory positive affect, mediating both the motivation (i.e. incentive salience) to engage with reward, as well as the positive emotions associated with anticipating a reward. "Liking", on the other hand, is associated with the pleasure derived from consuming a reward. The consciousness of reward-related processes has also been used to categorize reward in the context of anhedonia, as studies comparing implicit behavior versus explicit self-reports demonstrate a dissociation of the two. Learning has also been proposed as an independent facet of reward that may be impaired in conditions associated with anhedonia, but empirical evidence dissociating learning from either "liking" or "wanting" is lacking.

Anhedonia has also been used to refer to "affective blunting", "restricted range of affect", "emotional numbing", and "flat affect", particularly in the context of post-traumatic stress disorders. In PTSD patients, scales measuring these symptoms correlate strongly with scales that measure more traditional aspects of anhedonia, supporting this association.

Causes

Studies in clinical populations, healthy populations, and animal models have implicated a number of neurobiological substrates in anhedonia. Regions implicated in anhedonia include the prefrontal cortex as a whole, particularly the orbitofrontal cortex (OFC), the striatum, amygdala, anterior cingulate cortex (ACC), hypothalamus, and ventral tegmental area (VTA). Neuroimaging studies in humans have reported that deficits in consummatory aspects of reward are associated with abnormalities in the ventral striatum and medial prefrontal cortex, while deficits in anticipatory aspects of reward are related to abnormalities in hippocampal, dorsal ACC and prefrontal regions. These abnormalities are generally consistent with animal models, except for inconsistent findings with regard to the OFC. This inconsistency may be related to the difficulty in imaging the OFC due to its anatomical location, or the small number of studies performed on anhedonia; a number of studies have reported reduced activity in the OFC in schizophrenia and major depression, as well as a direct relationship between reduced activity and anhedonia. Researchers theorize that anhedonia may result from the breakdown in the brain's reward system, involving the neurotransmitter dopamine. Anhedonia can be characterised as "impaired ability to pursue, experience and/or learn about pleasure, which is often, but not always accessible to conscious awareness".

The conditions of akinetic mutism and negative symptoms are closely related. In akinetic mutism, a stroke or other lesion to the anterior cingulate cortex causes reduction in movement (akinetic) and speech (mutism). 

Occurrence


Major depressive disorder

Anhedonia occurs in roughly 70% of people with a major depressive disorder. Anhedonia is a core symptom of major depressive disorder; therefore, individuals experiencing this symptom can be diagnosed with depression, even in the absence of low/depressed mood. The Diagnostic and Statistical Manual of Mental Disorders (DSM) describes a "lack of interest or pleasure", but these can be difficult to discern given that people tend to become less interested in things which do not give them pleasure. The DSM criterion of weight loss is probably related, and many individuals with this symptom describe a lack of enjoyment of food. They can portray any of the non-psychotic symptoms and signs of depression.

Schizophrenia

Anhedonia is commonly listed as one component of negative symptoms in schizophrenia. Although five domains are usually used to classify negative symptoms, factor analysis of questionnaires yield two factors, with one including deficits in pleasure and motivation. People with schizophrenia retrospectively report experiencing fewer positive emotions than healthy individuals. However, "liking" or consummatory pleasure, is intact in schizophrenics, as they report experiencing the same degree of positive affect when presented with rewarding stimuli. Neuroimaging studies support this behavioral observation, as most studies report intact responses in the reward system (i.e. ventral striatum, VTA) to simple rewards. However, studies on monetary rewards sometimes report reduced responsiveness. More consistent reductions are observed with regard to emotional response during reward anticipation, which is reflected in a reduced responsiveness of both cortical and subcortical components of the reward system. Schizophrenia is associated with reduced positive prediction errors (a normal pattern of response to an unexpected reward), which a few studies have demonstrated to be correlated with negative symptoms. Schizophrenics demonstrate impairment in reinforcement learnings tasks only when the task requires explicit learning, or is sufficiently complex. Implicit reinforcement learning, on the other hand, is relatively intact. These deficits may be related to dysfunction in the ACC, OFC and dlPFC leading to abnormal representation of reward and goals.

Substance related disorders

Anhedonia is common in people who are dependent upon a wide variety of drugs, including alcohol, opioids, and nicotine. Although anhedonia becomes less severe over time, it is a significant predictor of relapse.

Post traumatic stress disorder

While PTSD is associated with reduced motivation, part of the anticipatory "wanting", it is also associated with elevated sensation seeking, and no deficits in physiological arousal, or self reported pleasure to positive stimuli. PTSD is also associated with blunted affect, which may be due to the high comorbidity with depression.

Parkinson's disease

Anhedonia occurs frequently in Parkinson's disease, with rates between 7%–45% being reported. Whether or not anhedonia is related to the high rates of depression in Parkinson's disease is unknown.

Sexual anhedonia

Sexual anhedonia in males is also known as 'ejaculatory anhedonia'. This condition means that the man will ejaculate with no accompanying sense of pleasure. 

The condition is most frequently found in males, but women can suffer from lack of pleasure when the body goes through the orgasm process as well.

Sexual anhedonia may be caused by:
It is very uncommon that a neurological examination and blood tests can determine the cause of a specific case of sexual anhedonia.

Patients may be prescribed sustained-release bupropion to aid in treatment, which has been shown to relieve sexual dysfunction even in patients without depression.

Social anhedonia



Definition

Social anhedonia is defined as a disinterest in social contact and a lack of pleasure in social situations, and is characterized by social withdrawal. This characteristic typically manifests as an indifference to other people. In contrast to introversion, a nonpathological dimension of human personality, social anhedonia represents a deficit in the ability to experience pleasure. Additionally, social anhedonia differs from social anxiety in that social anhedonia is predominantly typified by diminished positive affect, while social anxiety is distinguished by both decreased positive affect and exaggerated negative affect.

This trait is currently seen as a central characteristic to, as well as a predictor of, schizophrenia spectrum disorders, as it is seen as a potential evolution of most personality disorders, if the patient is above age 24, when prodromal schizophrenia may be excluded.

Signs and symptoms

  • Decreased ability to experience interpersonal pleasure
  • Social withdrawal/isolation
  • Decreased capacity for social contact and interaction
  • Lack of close friends and intimate relationships, and decreased quality of those relationships
  • Poor social adjustment
  • Decreased positive affect
  • Flat affect
  • Depressed mood
  • State-related anxiety

Background and early clinical observation

The term anhedonia is derived from the Greek an-, "without" and hēdonē, "pleasure". Interest in the nature of pleasure and its absence dates back to ancient Greek philosophers such as Epicurus. The symptoms of anhedonia were introduced to the realm of psychopathology in 1809 by John Haslam, who characterized a patient suffering from schizophrenia as indifferent to “those objects and pursuits which formerly proved sources of delight and instruction.”. The concept was formally coined by Théodule-Armand Ribot and later used by psychiatrists Paul Eugen Bleuler and Emil Kraepelin to describe a core symptom of schizophrenia. In particular, Rado postulated that schizotypes, or individuals with the schizophrenic phenotype, have two key genetic deficits, one related to the ability to feel pleasure (anhedonia) and one related to proprioception. In 1962 Meehl furthered Rado's theory through the introduction of the concept of schizotaxia, a genetically-driven neural integrative defect thought to give rise to the personality type of schizotypy. Loren and Jean Chapman further distinguished between two types of anhedonia: physical anhedonia, or a deficit in the ability to experience physical pleasure, and social, or a deficit in the ability to experience interpersonal pleasure.

Recent research suggests that social anhedonia may represent a prodrome of psychotic disorders. First-degree relatives of individuals with schizophrenia show elevated levels of social anhedonia, higher baseline scores of social anhedonia are associated with later development of schizophrenia. These findings provide support for the conjecture that it represents a genetic risk marker for schizophrenia-spectrum disorders.

Additionally, elevated levels of social anhedonia in patients with schizophrenia have been linked to poorer social functioning. Socially anhedonic individuals perform worse on a number of neuropsychological tests than non-anhedonic participants, and show similar physiological abnormalities seen in patients with schizophrenia.

Comorbidity

Anhedonia is present in several forms of psychopathology.

Depression

Social anhedonia is observed in both depression and schizophrenia. However, social anhedonia is a state related to the depressive episode and the other is trait related to the personality construct associated with schizophrenia. These individuals both tend to score highly on self-report measures of social anhedonia. Blanchard, Horan, and Brown (2001) demonstrated that, although both the depression and the schizophrenia patient groups can look very similar in terms of social anhedonia cross-sectionally, over time as individuals with depression experience symptom remission, they show fewer signs of social anhedonia, while individuals with schizophrenia do not. Blanchard and colleagues (2011) found individuals with social anhedonia also had elevated rates of lifetime mood disorders including depression and dysthymia compared to controls.

Social anxiety

As mentioned above, social anxiety and social anhedonia differ in important ways. However, social anhedonia and social anxiety are also often comorbid. People with social anhedonia may display increased social anxiety and be at increased risk for social phobias and generalized anxiety disorder. It has yet to be determined what the exact relationship between social anhedonia and social anxiety is, and if one potentiates the other. Individuals with social anhedonia may display increased stress reactivity, meaning that they feel more overwhelmed or helpless in response to a stressful event compared to control subjects who experience the same type of stressor. This dysfunctional stress reactivity may correlate with hedonic capacity, providing a potential explanation for the increased anxiety symptoms experienced in people with social anhedonia. In an attempt to separate out social anhedonia from social anxiety, the Revised Social Anhedonia Scale didn't include items that potentially targeted social anxiety. However, more research must be conducted on the underlying mechanisms through which social anhedonia overlaps and interacts with social anxiety. The efforts of the “social processes” RDoC initiative will be crucial in differentiating between these components of social behavior that may underlie mental illnesses such as schizophrenia.

Primary relevance in schizophrenia and schizophrenia spectrum disorders

Social anhedonia is a core characteristic of schizotypy, which is defined as a continuum of personality traits that can range from normal to disordered and contributes to risk for psychosis and schizophrenia. Social anhedonia is a dimension of both negative and positive schizotypy. It involves social and interpersonal deficits, but is also associated with cognitive slippage and disorganized speech, both of which fall into the category of positive schizotypy. Not all people with schizophrenia display social anhedonia and likewise, people who have social anhedonia may never be diagnosed with a schizophrenia-spectrum disorder if they do not have the positive and cognitive symptoms that are most frequently associated with most schizophrenia-spectrum disorders.

Social anhedonia may be a valid predictor of future schizophrenia-spectrum disorders; young adults with social anhedonia perform in a similar direction to schizophrenia patients in tests of cognition and social behavior, showing potential predictive validity. Social anhedonia usually manifests in adolescence, possibly because of a combination of the occurrence of critical neuronal development and synaptic pruning of brain regions important for social behavior and environmental changes, when adolescents are in the process of becoming individuals and gaining more independence. 

Treatment

There is no validated treatment for social anhedonia. Future research should focus on genetic and environmental risk factors to home in on specific brain regions and neurotransmitters that may be implicated in social anhedonia's cause and could be targeted with medication or behavioral treatments. Social support may also play a valuable role in the treatment of social anhedonia. Blanchard et al. (2011) found that a greater number of social supports, as well as a greater perceived social support network, were related to fewer schizophrenia-spectrum symptoms and to better general functioning within the social anhedonia group. So far, no medicine has been developed to specifically target anhedonia. 

Gender differences

In the general population, males score higher than females on measures of social anhedonia. This sex difference is stable throughout time (from adolescence into adulthood) and is also seen in people with schizophrenia-spectrum disorders. These results may reflect a more broad pattern of interpersonal and social deficits seen in schizophrenia-spectrum disorders. On average, males with schizophrenia are diagnosed at a younger age, have more severe symptoms, worse treatment prognosis, and a decrease in overall quality of life compared to females with the disorder. These results, coupled with the sex difference seen in social anhedonia, outline the necessity for research on genetic and hormonal characteristics that differ between males and females, and that may increase risk or resilience for mental illnesses such as schizophrenia.

Assessing social anhedonia

There are several self-report psychometric measures of schizotypy which each contain subscales related to social anhedonia:
  • Revised Social Anhedonia Scale—Chapman Psychosis Proneness Scales
  • No Close Friends Subscale—Schizotypyal Personality Questionnaire 
  • Introverted Anhedonia Subscale—Oxford Liverpool Inventory of Feelings & Experiences 

Genetic components

L.J. and J.P. Chapman were the first to discuss the possibility that social anhedonia may stem from a genetic vulnerability. The Disrupted in Schizophrenia 1 (DISC1) gene has been consistently associated with risk for, and cause of, schizophrenia-spectrum disorders and other mental illnesses. More recently, DISC1 has been associated with social anhedonia within the general population. Tomppo (2009) identified a specific DISC1 allele that is associated with an increase in characteristics of social anhedonia. They also identified a DISC1 allele associated with decreased characteristics of social anhedonia, that was found to be preferentially expressed in women. More research needs to be conducted, but social anhedonia may be an important intermediate phenotype (endophenotype) between genes associated with risk for schizophrenia and phenotype of the disorder. Continued study of social anhedonia and its genetic components will help researchers and clinicians learn more about the cause of schizophrenia-spectrum disorders.

Neurobiological correlates

Researchers studying the neurobiology of social anhedonia posit that this trait may be linked to dysfunction of reward-related systems in the brain. This circuitry is critical for the sensation of pleasure, the computation of reward benefits and costs, determination of the effort required to obtain a pleasant stimulus, deciding to obtain that stimulus, and increasing motivation to obtain the stimulus. In particular, the ventral striatum and areas of the prefrontal cortex (PFC), including the orbitofrontal cortex (OFC) and dorsolateral (dl) PFC, are critically involved in the experience of pleasure and the hedonic perception of rewards. With regards to neurotransmitter systems, opioid, gamma-Aminobutyric acid and endocannabinoid systems in the nucleus accumbens, ventral pallidum, and OFC mediate the hedonic perception of rewards. Activity in the PFC and ventral striatum have been found to be decreased in anhedonic individuals with major depressive disorder (MDD) and schizophrenia. However, schizophrenia may be less associated with decreased hedonic capacity and more with deficient reward appraisal.

Specific musical anhedonia

Recent studies have found people who do not have any issue processing musical tones or beat, yet receive no pleasure from listening to music. Specific musical anhedonia is distinct from Melophobia, the fear of music.
