Human nature

From Wikipedia, the free encyclopedia
Human nature refers to the distinguishing characteristics—including ways of thinking, feeling, and acting—which humans tend to have naturally.[1][2][3][4]

The questions of whether there truly are fixed characteristics, what these natural characteristics are, and what causes them are among the oldest and most important questions in philosophy and science. The science that examines human nature is known as psychology. The concept of human nature is traditionally contrasted not only with unusual human characteristics, but also with characteristics which are derived from specific cultures, and upbringings. The "nature versus nurture" debate is a well-known modern discussion about human nature in the natural science.

These questions have particularly important implications in economy, ethics, politics, and theology. This is partly because human nature can be regarded as both a source of norms of conduct or ways of life, as well as presenting obstacles or constraints on living a good life. The complex implications of such questions are also dealt with in art and literature, the question of what it is to be human.

Overview

The concept of nature as a standard by which to make judgments is traditionally said to have begun in Greek philosophy, at least as regards the Western and Middle Eastern languages and perspectives which are heavily influenced by it.[5]

The teleological approach of Aristotle came to be dominant by late classical and medieval times. By this account, human nature really causes humans to become what they become, and so it exists somehow independently of individual humans. This in turn has been understood as also showing a special connection between human nature and divinity. This approach understands human nature in terms of final and formal causes. In other words, nature itself (or a nature-creating divinity) has intentions and goals, similar somehow to human intentions and goals, and one of those goals is humanity living naturally. Such understandings of human nature see this nature as an "idea", or "form" of a human.[6]

However, the existence of this invariable and metaphysical human nature is a subject of much historical debate, continuing into modern times. Against this idea of a fixed human nature, the relative malleability of man has been argued especially strongly in recent centuries—firstly by early modernists such as Thomas Hobbes and Jean-Jacques Rousseau. In Rousseau's Emile, or On Education, Rousseau wrote: "We do not know what our nature permits us to be".[7] Since the early 19th century, thinkers such as Hegel, Marx, Kierkegaard, Nietzsche, Sartre, structuralists, and postmodernists have also sometimes argued against a fixed or innate human nature.

Charles Darwin's theory of evolution has changed the nature of the discussion, supporting the proposition that mankind's ancestors were not like mankind today. Still more recent scientific perspectives—such as behaviorism, determinism, and the chemical model within modern psychiatry and psychology—claim to be neutral regarding human nature. As in much of modern science, such disciplines seek to explain with little or no recourse to metaphysical causation.[8] They can be offered to explain human nature's origins and underlying mechanisms, or to demonstrate capacities for change and diversity which would arguably violate the concept of a fixed human nature.

Classical Greek philosophy

Philosophy in classical Greece is the ultimate origin[citation needed] of the Western conception of the nature of a thing. According to Aristotle, the philosophical study of human nature itself originated with Socrates, who turned philosophy from study of the heavens to study of the human things.[9] Socrates is said to have studied the question of how a person should best live, but he left no written works. It is clear from the works of his students Plato and Xenophon, and also by what was said about him by Aristotle (Plato's student), that Socrates was a rationalist and believed that the best life and the life most suited to human nature involved reasoning. The Socratic school was the dominant surviving influence in philosophical discussion in the Middle Ages, amongst Islamic, Christian, and Jewish philosophers.

The human soul in the works of Plato and Aristotle has a divided nature, divided in a specifically human way. One part is specifically human and rational, and divided into a part which is rational on its own, and a spirited part which can understand reason. Other parts of the soul are home to desires or passions similar to those found in animals. In both Aristotle and Plato, spiritedness (thumos) is distinguished from the other passions (epithumiai).[10] The proper function of the "rational" was to rule the other parts of the soul, helped by spiritedness. By this account, using one's reason is the best way to live, and philosophers are the highest types of humans.

Aristotle—Plato's most famous student—made some of the most famous and influential statements about human nature. In his works, apart from using a similar scheme of a divided human soul, some clear statements about human nature are made:
  • Man is a conjugal animal, meaning an animal which is born to couple when an adult, thus building a household (oikos) and, in more successful cases, a clan or small village still run upon patriarchal lines.[11]
  • Man is a political animal, meaning an animal with an innate propensity to develop more complex communities the size of a city or town, with a division of labor and law-making. This type of community is different in kind from a large family, and requires the special use of human reason.[12]
  • Man is a mimetic animal. Man loves to use his imagination (and not only to make laws and run town councils). He says "we enjoy looking at accurate likenesses of things which are themselves painful to see, obscene beasts, for instance, and corpses." And the "reason why we enjoy seeing likenesses is that, as we look, we learn and infer what each is, for instance, 'that is so and so.'"[13]
For Aristotle, reason is not only what is most special about humanity compared to other animals, but it is also what we were meant to achieve at our best. Much of Aristotle's description of human nature is still influential today. However, the particular teleological idea that humans are "meant" or intended to be something has become much less popular in modern times.[14]

For the Socratics, human nature, and all natures, are metaphysical concepts. Aristotle developed the standard presentation of this approach with his theory of four causes. Every living thing exhibits four aspects or "causes": matter, form, effect, and end. For example, an oak tree is made of plant cells (matter), grew from an acorn (effect), exhibits the nature of oak trees (form), and grows into a fully mature oak tree (end). Human nature is an example of a formal cause, according to Aristotle. Likewise, to become a fully actualized human being (including fully actualizing the mind) is our end. Aristotle (Nicomachean Ethics, Book X) suggests that the human intellect (νούς) is "smallest in bulk" but the most significant part of the human psyche, and should be cultivated above all else. The cultivation of learning and intellectual growth of the philosopher, which is thereby also the happiest and least painful life.

In Chinese thought

Human nature is a central question in Chinese philosophy.[15] Human nature was considered by Confucius and Mencius to be essentially good.[15] From the Song dynasty the theory of the original goodness of human beings dominated Confucian thought.[16] However, Hsun Tzu taught that human nature was essentially evil.[15] As suggested by these contrasting views, the question of human nature has generated a long debate among Chinese thinkers.[16]

Christian theology

In Christian theology, there are two ways of "conceiving human nature". The first is "spiritual, Biblical, and theistic", whereas the second is "natural, cosmical, and anti-theistic".[17] The focus in this section is on the former. As William James put it in his study of human nature from a religious perspective, "religion" has a "department of human nature".[18]

Various views of human nature have been held by theologians. However, there are some "basic assertions" in all "biblical anthropology".[19]
  1. "Humankind has its origin in God, its creator."
  2. "Humans bear the 'image of God'."
  3. Humans are "to rule the rest of creation".
The Bible contains no single "doctrine of human nature". Rather, it provides material for more philosophical descriptions of human nature.[20] For example, Creation as found in the Book of Genesis provides a theory on human nature.[21]

Catechism of the Catholic Church[22] in chapter "Dignity of the human person" has article about man as image of God, vocation to beatitude, freedom, human acts, passions, moral conscience, virtues and sin.

Created human nature

As originally created, the Bible describes "two elements" in human nature: "the body and the breath or spirit of life breathed into it by God". By this was created a "living soul", that is, a "living person".[23] According to Genesis 1:27, this living person was made in the "image of God".[24] From the biblical perspective, "to be human is to bear the image of God".[25]

Genesis does not elaborate the meaning of "the image of God", but scholars find suggestions. One is that being created in the image of God distinguishes human nature from that of the beasts.[26] Another is that as God is "able to make decisions and rule" so humans made in God's image are "able to make decisions and rule". A third is that mankind possesses an inherent ability "to set goals" and move toward them.[27] That God denoted creation as "good" suggests that Adam was "created in the image of God, in righteousness."[28]

Adam was created with ability to make "right choices", but also with the ability to choose sin, by which he fell from righteousness into a state of "sin and depravity".[29] Thus, according to the Bible, "humankind is not as God created it".[30]

Fallen human nature

By Adam's fall into sin, "human nature" became "corrupt", although it retains the image of God. Both the Old Testament and the New Testament teach that "sin is universal".[31] For example, Psalm 51:5 reads: "For behold I was conceived in iniquities; and in sins did my mother conceive me."[32] Jesus taught that everyone is a "sinner naturally" because it is mankind's "nature and disposition to sin".[33] Paul, in Romans 7:18, speaks of his "sinful nature".[34]

Such a "recognition that there is something wrong with the moral nature of man is found in all religions".[35] Augustine of Hippo coined a term for the assessment that all humans are born sinful: original sin.[36] Original sin is "the tendency to sin innate in all human beings".[37] The doctrine of original sin is held by the Catholic Church and most mainstream Protestant denominations, but rejected by the Eastern Orthodox Church, which holds the similar doctrine of ancestral fault.

"The corruption of original sin extends to every aspect of human nature": to "reason and will" as well as to "appetites and impulses". This condition is sometimes called "total depravity".[38] Total depravity does not mean that humanity is as "thoroughly depraved" as it could become.[39] Commenting on Romans 2:14, John Calvin writes that all people have "some notions of justice and rectitude ... which are implanted by nature" all people.[40]

Adam embodied the "whole of human nature" so when Adam sinned "all of human nature sinned".[41] The Old Testament does not explicitly link the "corruption of human nature" to Adam's sin. However, the "universality of sin" implies a link to Adam. In the New Testament, Paul concurs with the "universality of sin". He also makes explicit what the Old Testament implied: the link between humanity's "sinful nature" and Adam's sin[42] In Romans 5:19, Paul writes, "through [Adam's] disobedience humanity became sinful".[43] Paul also applied humanity's sinful nature to himself: "there is nothing good in my sinful nature."[44][45]

The theological "doctrine of original sin" as an inherent element of human nature is not based only on the Bible. It is in part a "generalization from obvious facts" open to empirical observation.[46]

Empirical view

A number of experts on human nature have described the manifestations of original (i.e., the innate tendency to) sin as empirical facts.
  • Biologist Richard Dawkins in his The Selfish Gene states that "a predominant quality" in a successful surviving gene is "ruthless selfishness". Furthermore, "this gene selfishness will usually give rise to selfishness in individual behavior".[47]
  • Child psychologist Burton L. White, PhD,[48] finds a "selfish" trait in children from birth, a trait that expresses itself in actions that are "blatantly selfish."[49]
  • Sociologist William Graham Sumner finds it a fact that "everywhere one meets "fraud, corruption, ignorance, selfishness, and all the other vices of human nature".[50] He enumerates "the vices and passions of human nature" as "cupidity, lust, vindictiveness, ambition, and vanity". Sumner finds such human nature to be universal: in all people, in all places, and in all stations in society.[51]
  • Psychiatrist Thomas Anthony Harris, MD, on the basis of his "data at hand", observes "sin, or badness, or evil, or 'human nature', whatever we call the flaw in our species, is apparent in every person". Harris calls this condition "intrinsic badness" or "original sin".[52]
Empirical discussion questioning the genetic exclusivity of such an intrinsic badness proposition is presented by researchers Elliott Sober and David Sloan Wilson. In their book, Unto Others: The Evolution and Psychology of Unselfish Behavior, they propose a theory of multilevel group selection in support of an inherent genetic "altruism" in opposition to the original sin exclusivity for human nature. [53]

Realistic view

Liberal theologians in the early 20th century described human nature as "basically good" needing only "proper training and education". But the above examples document the return to a "more realistic view" of human nature "as basically sinful and self-centered". Human nature needs "to be regenerated ... to be able to live the unselfish life".[54]

Regenerated human nature

According to the Bible, "Adam's disobedience corrupted human nature" but God mercifully "regenerates".[55] "Regeneration is a radical change" that involves a "renewal of our [human] nature".[56] Thus, to counter original sin, Christianity purposes "a complete transformation of individuals" by Christ.[57]

The goal of Christ's coming is that fallen humanity might be "conformed to or transformed into the image of Christ who is the perfect image of God", as in 2 Corinthians 4:4.[58] The New Testament makes clear the "universal need" for regeneration.[59] A sampling of biblical portrayals of regenerating human nature and the behavioral results follow.
  • being "transformed by the renewing of your minds" (Romans 12:2)[60]
  • being transformed from one's "old self" (or "old man") into a "new self" (or "new man") (Col.3:9-10)[61]
  • being transformed from people who "hate others" and "are hard to get along with" and who are "jealous, angry, and selfish" to people who are "loving, happy, peaceful, patient, kind, good, faithful, gentle, and self-controlled" (Galatians 5:20-23)[62]
  • being transformed from looking "to your own interests" to looking "to the interests of others" (Philippians 2:4)[63]

Early modern philosophy

One of the defining changes that occurred at the end of the Middle Ages was the end of the dominance of Aristotelian philosophy, and its replacement by a new approach to the study of nature, including human nature.[citation needed] In this approach, all attempts at conjecture about formal and final causes were rejected as useless speculation.[citation needed] Also, the term "law of nature" now applied to any regular and predictable pattern in nature, not literally a law made by a divine lawmaker, and, in the same way, "human nature" became not a special metaphysical cause, but simply whatever can be said to be typical tendencies of humans.[citation needed]

Although this new realism applied to the study of human life from the beginning—for example, in Machiavelli's works—the definitive argument for the final rejection of Aristotle was associated especially with Francis Bacon. Bacon sometimes wrote as if he accepted the traditional four causes ("It is a correct position that "true knowledge is knowledge by causes". And causes again are not improperly distributed into four kinds: the material, the formal, the efficient, and the final") but he adapted these terms and rejected one of the three:
But of these the final cause rather corrupts than advances the sciences, except such as have to do with human action. The discovery of the formal is despaired of. The efficient and the material (as they are investigated and received, that is, as remote causes, without reference to the latent process leading to the form) are but slight and superficial, and contribute little, if anything, to true and active science.[64]
This line of thinking continued with René Descartes, whose new approach returned philosophy or science to its pre-Socratic focus upon non-human things. Thomas Hobbes, then Giambattista Vico, and David Hume all claimed to be the first to properly use a modern Baconian scientific approach to human things.

Hobbes famously followed Descartes in describing humanity as matter in motion, just like machines. He also very influentially described man's natural state (without science and artifice) as one where life would be "solitary, poor, nasty, brutish and short".[65] Following him, John Locke's philosophy of empiricism also saw human nature as a tabula rasa. In this view, the mind is at birth a "blank slate" without rules, so data are added, and rules for processing them are formed solely by our sensory experiences.[66]

Jean-Jacques Rousseau pushed the approach of Hobbes to an extreme and criticized it at the same time. He was a contemporary and acquaintance of Hume, writing before the French Revolution and long before Darwin and Freud. He shocked Western civilization with his Second Discourse by proposing that humans had once been solitary animals, without reason or language or communities, and had developed these things due to accidents of pre-history. (This proposal was also less famously made by Giambattista Vico.) In other words, Rousseau argued that human nature was not only not fixed, but not even approximately fixed compared to what had been assumed before him. Humans are political, and rational, and have language now, but originally they had none of these things.[67] This in turn implied that living under the management of human reason might not be a happy way to live at all, and perhaps there is no ideal way to live. Rousseau is also unusual in the extent to which he took the approach of Hobbes, asserting that primitive humans were not even naturally social. A civilized human is therefore not only imbalanced and unhappy because of the mismatch between civilized life and human nature, but unlike Hobbes, Rousseau also became well known for the suggestion that primitive humans had been happier, "noble savages".[68]

Rousseau's conception of human nature has been seen as the origin of many intellectual and political developments of the 19th and 20th centuries.[69] He was an important influence upon Kant, Hegel, and Marx, and the development of German idealism, historicism, and romanticism.

What human nature did entail, according to Rousseau and the other modernists of the 17th and 18th centuries, were animal-like passions that led humanity to develop language and reasoning, and more complex communities (or communities of any kind, according to Rousseau).

In contrast to Rousseau, David Hume was a critic of the oversimplifying and systematic approach of Hobbes, Rousseau, and some others whereby, for example, all human nature is assumed to be driven by variations of selfishness. Influenced by Hutcheson and Shaftesbury, he argued against oversimplification. On the one hand, he accepted that, for many political and economic subjects, people could be assumed to be driven by such simple selfishness, and he also wrote of some of the more social aspects of "human nature" as something which could be destroyed, for example if people did not associate in just societies. On the other hand, he rejected what he called the "paradox of the sceptics", saying that no politician could have invented words like "'honourable' and 'shameful,' 'lovely' and 'odious,' 'noble' and 'despicable'", unless there was not some natural "original constitution of the mind".[70]

Hume—like Rousseau—was controversial in his own time for his modernist approach, following the example of Bacon and Hobbes, of avoiding consideration of metaphysical explanations for any type of cause and effect. He was accused of being an atheist. He wrote:
We needn't push our researches so far as to ask "Why do we have humanity, i.e. a fellow-feeling with others?" It's enough that we experience this as a force in human nature. Our examination of causes must stop somewhere.[70]
After Rousseau and Hume, the nature of philosophy and science changed, branching into different disciplines and approaches, and the study of human nature changed accordingly. Rousseau's proposal that human nature is malleable became a major influence upon international revolutionary movements of various kinds, while Hume's approach has been more typical in Anglo-Saxon countries, including the United States.[citation needed]

Natural science

As the sciences concerned with humanity split up into more specialized branches, many of the key figures of this evolution expressed influential understandings about human nature.[citation needed] Charles Darwin gave a widely accepted scientific argument for what Rousseau had already argued from a different direction, that humans and other animal species have no truly fixed nature, at least in the very long term. However, he also gave modern biology a new way of understanding how human nature does exist in a normal human time-frame, and how it is caused.[citation needed]

E. O. Wilson's sociobiology and closely related theory of evolutionary psychology give scientific arguments against the "tabula rasa" hypotheses of Hobbes, Locke, and Rousseau. In his book Consilience: The Unity of Knowledge (1998), Wilson claimed that it was time for a cooperation of all the sciences to explore human nature. He defined human nature as a collection of epigenetic rules: the genetic patterns of mental development. Cultural phenomena, rituals, etc. are products, not part of human nature. Until now, these phenomena were only part of psychological, sociological, and anthropological studies. Wilson proposes that they can be part of interdisciplinary research.

Instinct

From Wikipedia, the free encyclopedia
Instinct or innate behavior is the inherent inclination of a living organism towards a particular complex behavior. The simplest example of an instinctive behavior is a fixed action pattern (FAP), in which a very short to medium length sequence of actions, without variation, are carried out in response to a clearly defined stimulus.

Any behavior is instinctive if it is performed without being based upon prior experience (that is, in the absence of learning), and is therefore an expression of innate biological factors. Sea turtles, newly hatched on a beach, will automatically move toward the ocean. A marsupial climbs into its mother's pouch upon being born. Honeybees communicate by dancing in the direction of a food source without formal instruction. Other examples include animal fighting, animal courtship behavior, internal escape functions, and the building of nests.

Instincts are inborn complex patterns of behavior that exist in most members of the species, and should be distinguished from reflexes, which are simple responses of an organism to a specific stimulus, such as the contraction of the pupil in response to bright light or the spasmodic movement of the lower leg when the knee is tapped. The absence of volitional capacity must not be confused with an inability to modify fixed action patterns. For example, people may be able to modify a stimulated fixed action pattern by consciously recognizing the point of its activation and simply stop doing it, whereas animals without a sufficiently strong volitional capacity may not be able to disengage from their fixed action patterns, once activated.[1]

The role of instincts in determining the behavior of animals varies from species to species. The more complex the neural system of an animal, the greater is the role of the cerebral cortex and social learning, and instincts play a lesser role. A comparison between a crocodile and an elephant illustrates how mammals for example are heavily dependent on social learning. Lionesses and chimpanzees raised in zoos away from their birth mothers most often reject their own offspring because they have not been taught the skills of mothering.[citation needed] Such is not the case with simpler species such as reptiles.

In everyday speech, the word instinct is often used to refer to intuition or even clairvoyance.

History

In biology

Jean Henri Fabre (1823-1915), an entomologist, considered instinct to be any behavior which did not require cognition or consciousness to perform. Fabre's inspiration was his intense study of insects, some of whose behaviors he wrongly considered fixed and not subject to environmental influence.[2]

Instinct as a concept fell out of favor in the 1920s with the rise of behaviorism and such thinkers as B. F. Skinner, which held that most significant behavior is learned.

An interest in innate behaviors arose again in the 1950s with Konrad Lorenz and Nikolaas Tinbergen, who made the distinction between instinct and learned behaviors. Our modern understanding of instinctual behavior in animals owes much to their work. For instance, there exists a sensitive period for a bird in which it learns the identity of its mother. Konrad Lorenz famously had a goose imprint on his boots. Thereafter the goose would follow whoever wore the boots. The identity of the goose's mother was learned, but the goose's behavior towards the boots was instinctive.[citation needed]

In psychology

The term "instinct" in psychology was first used in the 1870s by Wilhelm Wundt. By the close of the 19th century, most repeated behavior was considered instinctual. In a survey of the literature at that time, one researcher chronicled 4,000 human "instincts," having applied this label to any behavior that was repetitive.[citation needed] As research became more rigorous and terms better defined, instinct as an explanation for human behavior became less common. In a conference in 1960, chaired by Frank Beach, a pioneer in comparative psychology, and attended by luminaries in the field, the term was restricted in its application.[citation needed] During the 1960s and 1970s, textbooks still contained some discussion of instincts in reference to human behavior. By the year 2000, a survey of the 12 best selling textbooks in Introductory Psychology revealed only one reference to instincts, and that was in regard to Sigmund Freud's referral to the "id" instincts.[citation needed]. In this sense, instincts appeared to have become regarded as increasingly superfluous in trying to understand human psychological behavior.

Psychologist Abraham Maslow argued that humans no longer have instincts because we have the ability to override them in certain situations. He felt that what is called instinct is often imprecisely defined, and really amounts to strong drives. For Maslow, an instinct is something which cannot be overridden, and therefore while the term may have applied to humans in the past, it no longer does.[3]

The book Instinct (1961) established a number of criteria which distinguish instinctual from other kinds of behavior. To be considered instinctual, a behavior must: a) be automatic, b) be irresistible, c) occur at some point in development, d) be triggered by some event in the environment, e) occur in every member of the species, f) be unmodifiable, and g) govern behavior for which the organism needs no training (although the organism may profit from experience and to that degree the behavior is modifiable).[4]

In a classic paper published in 1972,[5] the psychologist Richard Herrnstein decries Fabre's opinions on instinct (see: In biology section).

In behavioral sciences

In Information behavior: An Evolutionary Instinct (2010, pp. 35–42), Amanda Spink notes that "currently in the behavioral sciences instinct is generally understood as the innate part of behavior that emerges without any training or education in humans." She claims that the viewpoint that information behavior has an instinctive basis is grounded in the latest thinking on human behavior. Furthermore, she notes that "behaviors such as cooperation, sexual behavior, child rearing and aesthetics are [also] seen as 'evolved psychological mechanisms' with an instinctive basis."[6][7][8] Spink adds that Steven Pinker similarly asserts that language acquisition is instinctive in humans in his book The Language Instinct (1994).

Reflexes

Examples of behaviors that do not require conscious will include many reflexes. The stimulus in a reflex may not require brain activity but instead may travel to the spinal cord as a message that is then transmitted back through the body, tracing a path called the reflex arc. Reflexes are similar to fixed action patterns in that most reflexes meet the criteria of a FAP. However, a fixed action pattern can be processed in the brain as well; a male stickleback's instinctive aggression towards anything red during his mating season is such an example. Examples of instinctive behaviors in humans include many of the primitive reflexes, such as rooting and suckling, behaviors which are present in mammals. In rats, it has been observed that innate responses are related to specific chemicals, and these chemicals are detected by two organs located in the nose: the vomeronasal organ (VNO) and the main olfactory epithelium (MOE).[9]

Maturational

Some instinctive behaviors depend on maturational processes to appear. For instance, we commonly refer to birds "learning" to fly. However, young birds have been experimentally reared in devices that prevent them from moving their wings until they reached the age at which their cohorts were flying. These birds flew immediately and normally when released, showing that their improvement resulted from neuromuscular maturation and not true learning.[10]

In evolution

Imprinting provides one example of instinct.[11] This complex response may involve visual, auditory, and olfactory cues in the environment surrounding an organism.[citation needed] In some cases, imprinting attaches an offspring to its parent, which is a reproductive benefit to offspring survival.[12] If an offspring has attachment to a parent, it is more likely to stay nearby under parental protection. Attached offspring are also more likely to learn from a parental figure when interacting closely. (Reproductive benefits are a driving force behind natural selection.)

Environment is an important factor in how innate behavior has evolved.[citation needed] A hypothesis of Michael McCollough, a positive psychologist, explains that environment plays a key role in human behaviors such as forgiveness and revenge. This hypothesis theorizes that various social environments cause either forgiveness or revenge to prevail. McCollough relates his theory to game theory.[13] In a tit-for-tat strategy, cooperation and retaliation are comparable to forgiveness and revenge. The choice between the two can be beneficial or detrimental, depending on what the partner-organism chooses. Though this psychological example of game theory does not have such directly measurable results, it provides an interesting theory of unique thought. From a more biological standpoint, the brain's limbic system operates as the main control-area for response to certain stimuli, including a variety of instinctual behavior. The limbic system processes external stimuli related to emotions, social activity, and motivation, which propagates a behavioral response. Some behaviors include maternal care, aggression, defense, and social hierarchy. These behaviors are influenced by sensory input — sight, sound, touch, and smell.

Within the circuitry of the limbic system, there are various places where evolution could have taken place, or could take place in the future. For example, many rodents have receptors in the vomeronasal organ that respond explicitly to predator stimuli that specifically relate to that individual species of rodent. The reception of a predatory stimulus usually creates a response of defense or fear.[14][need quotation to verify] Mating in rats follows a similar mechanism. The vomeronasal organ and the main olfactory epithelium, together called the olfactory system, detect pheromones from the opposite sex. These signals then travel to the medial amygdala, which disperses the signal to a variety of brain parts. The pathways involved with innate circuitry are extremely specialized and specific.[15] Various organs and sensory receptors play parts in this complex process.

Instinct is a phenomenon that can be investigated from a multitude of angles: genetics, limbic system, nervous pathways, and environment. Researchers can study levels of instincts: from molecular to groups of individuals. Extremely specialized systems have evolved, resulting in individuals which exhibit behaviors without learning them. Innate behavior is an important and interesting aspect of the biological world that people come into contact with every day.[citation needed]

Unconscious mind

From Wikipedia, the free encyclopedia

The unconscious mind (or the unconscious) consists of the processes in the mind which occur automatically and are not available to introspection, and include thought processes, memories, interests, and motivations.[1]

Even though these processes exist well under the surface of conscious awareness they are theorized to exert an impact on behavior. The term was coined by the 18th-century German Romantic philosopher Friedrich Schelling and later introduced into English by the poet and essayist Samuel Taylor Coleridge.[2][3]

Empirical evidence suggests that unconscious phenomena include repressed feelings, automatic skills, subliminal perceptions, thoughts, habits, and automatic reactions,[1] and possibly also complexes, hidden phobias and desires.

The concept was popularized by the Austrian neurologist and psychoanalyst Sigmund Freud. In psychoanalytic theory, unconscious processes are understood to be directly represented in dreams, as well as in slips of the tongue and jokes.

Thus the unconscious mind can be seen as the source of dreams and automatic thoughts (those that appear without any apparent cause), the repository of forgotten memories (that may still be accessible to consciousness at some later time), and the locus of implicit knowledge (the things that we have learned so well that we do them without thinking).

It has been argued that consciousness is influenced by other parts of the mind. These include unconsciousness as a personal habit, being unaware, and intuition. Phenomena related to semi-consciousness include awakening, implicit memory, subliminal messages, trances, hypnagogia, and hypnosis. While sleep, sleepwalking, dreaming, delirium, and comas may signal the presence of unconscious processes, these processes are seen as symptoms rather than the unconscious mind itself.

Some critics have doubted the existence of the unconscious.[4][5][6]

Historical overview

The term "unconscious" (German: Unbewusste) was coined by the 18th-century German Romantic philosopher Friedrich Schelling (in his System of Transcendental Idealism, ch. 6, § 3) and later introduced into English by the poet and essayist Samuel Taylor Coleridge (in his Biographia Literaria).[2][3] Some rare earlier instances of the term "unconsciousness" (Unbewußtseyn) can be found in the work of the 18th-century German physician and philosopher Ernst Platner.[7][8]

Influences on thinking that originate from outside of an individual's consciousness were reflected in the ancient ideas of temptation, divine inspiration, and the predominant role of the gods in affecting motives and actions. The idea of internalised unconscious processes in the mind was also instigated in antiquity and has been explored across a wide variety of cultures. Unconscious aspects of mentality were referred to between 2500 and 600 BC in the Hindu texts known as the Vedas, found today in Ayurvedic medicine.[9][10][11]

Paracelsus is credited as the first to make mention of an unconscious aspect of cognition in his work Von den Krankheiten (translates as "About illnesses", 1567), and his clinical methodology created a cogent system that is regarded by some as the beginning of modern scientific psychology.[12] William Shakespeare explored the role of the unconscious[13] in many of his plays, without naming it as such.[14][15][16] In addition, Western philosophers such as Arthur Schopenhauer,[17][18] Baruch Spinoza, Gottfried Leibniz, Johann Gottlieb Fichte, Georg Wilhelm Friedrich Hegel, Eduard von Hartmann, Søren Kierkegaard, and Friedrich Nietzsche[19] used the word unconscious.

In 1880, Edmond Colsenet supports at the Sorbonne, a philosophy thesis on the unconscious.[20] Elie Rabier and Alfred Fouillee perform syntheses of the unconscious "at a time when Freud was not interested in the concept".[21]

Psychology

Psychologist Jacques Van Rillaer points out that, "the unconscious was not discovered by Freud. In 1890, when psychoanalysis was still unheard of, William James, in his monumental treatise on psychology (The Principles of Psychology), examined the way Schopenhauer, von Hartmann, Janet, Binet and others had used the term 'unconscious' and 'subconscious'".[22] Historian of psychology Mark Altschule observes that, "It is difficult—or perhaps impossible—to find a nineteenth-century psychologist or psychiatrist who did not recognize unconscious cerebration as not only real but of the highest importance."[23]

Van Rilliaer could have also mentioned that Eduard von Hartmann published a book dedicated to this topic, Philosophy of the Unconscious, in 1869 -- long before anybody else.

Furthermore, 19th century German psychologists, Gustav Fechner and Wilhelm Wundt, had begun to use the term in their experimental psychology, in the context of manifold, jumbled sense data that the mind organizes at an unconscious level before revealing it as a cogent totality in conscious form."[24]

Freud's view

An iceberg is often (though misleadingly) used to provide a visual representation of Freud's theory that most of the human mind operates unconsciously.

Sigmund Freud and his followers developed an account of the unconscious mind. It plays an important role in psychoanalysis.

Freud divided the mind into the conscious mind (or the ego) and the unconscious mind. The latter was then further divided into the id (or instincts and drive) and the superego (or conscience). In this theory, the unconscious refers to the mental processes of which individuals make themselves unaware.[25] Freud proposed a vertical and hierarchical architecture of human consciousness: the conscious mind, the preconscious, and the unconscious mind—each lying beneath the other. He believed that significant psychic events take place "below the surface" in the unconscious mind,[26] like hidden messages from the unconscious. He interpreted such events as having both symbolic and actual significance.

In psychoanalytic terms, the unconscious does not include all that is not conscious, but rather what is actively repressed from conscious thought or what a person is averse to knowing consciously. Freud viewed the unconscious as a repository for socially unacceptable ideas, wishes or desires, traumatic memories, and painful emotions put out of mind by the mechanism of psychological repression. However, the contents did not necessarily have to be solely negative. In the psychoanalytic view, the unconscious is a force that can only be recognized by its effects—it expresses itself in the symptom. In a sense, this view places the conscious self as an adversary to its unconscious, warring to keep the unconscious hidden. Unconscious thoughts are not directly accessible to ordinary introspection, but are supposed to be capable of being "tapped" and "interpreted" by special methods and techniques such as meditation, free association (a method largely introduced by Freud), dream analysis, and verbal slips (commonly known as a Freudian slip), examined and conducted during psychoanalysis. Seeing as these unconscious thoughts are normally cryptic, psychoanalysts are considered experts in interpreting their messages.[citation needed]

Freud based his concept of the unconscious on a variety of observations. For example, he considered "slips of the tongue" to be related to the unconscious in that they often appeared to show a person's true feelings on a subject. For example, "I decided to take a summer curse". This example shows a slip of the word "course" where the speaker accidentally used the word curse which would show that they have negative feelings about having to do this. Freud noticed that also his patient's dreams expressed important feelings they were unaware of. After these observations, he came to the conclusion that psychological disturbances are largely caused by personal conflicts existing at the unconscious level. His psychoanalytic theory acts to explain personality, motivation and mental disorders by focusing on unconscious determinants of behavior.[27]

Freud later used his notion of the unconscious in order to explain certain kinds of neurotic behavior.[28] The theory of the unconscious was substantially transformed by later psychiatrists, among them Carl Jung and Jacques Lacan.

In his 1932/1933 conferences, Freud "proposes to abandon the notion of the unconscious that ambiguous judge".[29]

Jung's view

Carl Gustav Jung, a Swiss psychiatrist, developed the concept further. He agreed with Freud that the unconscious is a determinant of personality, but he proposed that the unconscious be divided into two layers: the personal unconscious and the collective unconscious. The personal unconscious is a reservoir of material that was once conscious but has been forgotten or suppressed, much like Freud's notion. The collective unconscious, however, is the deepest level of the psyche, containing the accumulation of inherited psychic structures and archetypal experiences. Archetypes are not memories but images with universal meanings that are apparent in the culture's use of symbols. The collective unconscious is therefore said to be inherited and contain material of an entire species rather than of an individual.[30] Every person shares the collective unconscious with the entire human species, as Jung puts it: [the] "whole spiritual heritage of mankind's evolution, born anew in the brain structure of every individual".[31]
In addition to the structure of the unconscious, Jung differed from Freud in that he did not believe that sexuality was at the base of all unconscious thoughts.[32]

Controversy

The notion that the unconscious mind exists at all has been disputed.

Franz Brentano rejected the concept of the unconscious in his 1874 book Psychology from an Empirical Standpoint, although his rejection followed largely from his definitions of consciousness and unconsciousness.[33]

Jean-Paul Sartre offers a critique of Freud's theory of the unconscious in Being and Nothingness, based on the claim that consciousness is essentially self-conscious. Sartre also argues that Freud's theory of repression is internally flawed. Philosopher Thomas Baldwin argues that Sartre's argument is based on a misunderstanding of Freud.[4]

Erich Fromm contends that, "The term 'the unconscious' is actually a mystification (even though one might use it for reasons of convenience, as I am guilty of doing in these pages). There is no such thing as the unconscious; there are only experiences of which we are aware, and others of which we are not aware, that is, of which we are unconscious. If I hate a man because I am afraid of him, and if I am aware of my hate but not of my fear, we may say that my hate is conscious and that my fear is unconscious; still my fear does not lie in that mysterious place: 'the' unconscious."[34]

John Searle has offered a critique of the Freudian unconscious. He argues that the Freudian cases of shallow, consciously held mental states would be best characterized as 'repressed consciousness,' while the idea of more deeply unconscious mental states is more problematic. He contends that the very notion of a collection of "thoughts" that exist in a privileged region of the mind such that they are in principle never accessible to conscious awareness, is incoherent. This is not to imply that there are not "nonconscious" processes that form the basis of much of conscious life. Rather, Searle simply claims that to posit the existence of something that is like a "thought" in every way except for the fact that no one can ever be aware of it (can never, indeed, "think" it) is an incoherent concept. To speak of "something" as a "thought" either implies that it is being thought by a thinker or that it could be thought by a thinker. Processes that are not causally related to the phenomenon called thinking are more appropriately called the nonconscious processes of the brain.[35]

Other critics of the Freudian unconscious include David Stannard,[5] Richard Webster,[6] Ethan Watters,[36] Richard Ofshe,[36] and Eric Thomas Weber.[37]

David Holmes[38] examined sixty years of research about the Freudian concept of "repression", and concluded that there is no positive evidence for this concept. Given the lack of evidence for many Freudian hypotheses, some scientific researchers proposed the existence of unconscious mechanisms that are very different from the Freudian ones. They speak of a "cognitive unconscious" (John Kihlstrom),[39][40] an "adaptive unconscious" (Timothy Wilson),[41] or a "dumb unconscious" (Loftus & Klinger),[42] which executes automatic processes but lacks the complex mechanisms of repression and symbolic return of the repressed.

In modern cognitive psychology, many researchers have sought to strip the notion of the unconscious from its Freudian heritage, and alternative terms such as "implicit" or "automatic" have come into currency. These traditions emphasize the degree to which cognitive processing happens outside the scope of cognitive awareness, and show that things we are unaware of can nonetheless influence other cognitive processes as well as behavior.[43][44][45][46][47] Active research traditions related to the unconscious include implicit memory (see priming, implicit attitudes), and nonconscious acquisition of knowledge (see Lewicki, see also the section on cognitive perspective, below).

Dreams

Freud

In terms of the unconscious, the purpose of dreams, as stated by Freud, is to fulfill repressed wishes through the process of dreaming, since they cannot be fulfilled in real life. For example, if someone was to rob a store and feel guilty about it, they might dream about a scenario in which their actions were justified and renders them blameless. Freud asserted that the wish-fulfilling aspect of the dream may be disguised due to the difficulty in distinguishing between manifest content and latent content. The manifest content consists of the plot of a dream at the surface level. The latent content refers to the hidden or disguised meaning of the events in the plot. The latent content of the dream is what supports the idea of wish fulfillment. It represents the intimate information in the dreamer's current issues and childhood conflict.[48]

Opposing theories

In response to Freud's theory on dreams, other psychologists have come up with theories to counter his argument. Theorist Rosalind Cartwright proposed that dreams provide people with the opportunity to act out and work through everyday problems and emotional issues in a non-real setting with no consequences. According to her cognitive problem solving view, a large amount of continuity exists between our waking thought and the thoughts that exist in dreams. Proponents of this view believe that dreams allow participation in creative thinking and alternate ways to handle situations when dealing with personal issues because dreams are not restrained by logic or realism.[48]

In addition to this, Allan Hobson and colleagues came up with the activation-synthesis hypothesis which proposes that dreams are simply the side effects of the neural activity in the brain that produces beta brain waves during REM sleep that are associated with wakefulness. According to this hypothesis, neurons fire periodically during sleep in the lower brain levels and thus send random signals to the cortex. The cortex then synthesizes a dream in reaction to these signals in order to try to make sense of why the brain is sending them. However, the hypothesis does not state that dreams are meaningless, it just downplays the role that emotional factors play in determining dreams.[48]

Contemporary cognitive psychology

Research

While, historically, the psychoanalytic research tradition was the first to focus on the phenomenon of unconscious mental activity, there is an extensive body of conclusive research and knowledge in contemporary cognitive psychology devoted to the mental activity that is not mediated by conscious awareness.

Most of that (cognitive) research on unconscious processes has been done in the mainstream, academic tradition of the information processing paradigm. As opposed to the psychoanalytic tradition, driven by the relatively speculative (in the sense of being hard to empirically verify) theoretical concepts such as the Oedipus complex or Electra complex, the cognitive tradition of research on unconscious processes is based on relatively few theoretical assumptions and is very empirically oriented (i.e., it is mostly data driven). Cognitive research has revealed that automatically, and clearly outside of conscious awareness, individuals register and acquire more information than what they can experience through their conscious thoughts. (See Augusto, 2010, for a recent comprehensive survey.)[49]

Unconscious processing of information about frequency

For example, an extensive line of research conducted by Hasher and Zacks[50] has demonstrated that individuals register information about the frequency of events automatically (i.e., outside of conscious awareness and without engaging conscious information processing resources). Moreover, perceivers do this unintentionally, truly "automatically," regardless of the instructions they receive, and regardless of the information processing goals they have. Interestingly, the ability to unconsciously and relatively accurately tally the frequency of events appears to have little or no relation to the individual's age,[51] education, intelligence, or personality, thus it may represent one of the fundamental building blocks of human orientation in the environment and possibly the acquisition of procedural knowledge and experience, in general.
