Sigmund Freud (), born Sigismund Schlomo Freud (May 6 1856 – September 23 1939), was an Austrian neurologist and psychiatrist who founded the psychoanalytic school of psychology. Freud is best known for his theories of the unconscious mind, especially involving the mechanism of repression; his redefinition of sexual desire as the primary motivational energy of human life, directed toward a wide variety of objects; and his therapeutic techniques, especially his theory of transference in the therapeutic relationship and the presumed value of dreams as sources of insight into unconscious desires.

He is commonly referred to as "the father of psychoanalysis" and his work has been highly influential — popularizing such notions as the unconscious, the Oedipus complex, defense mechanisms, Freudian slips and dream symbolism—while also making a long-lasting impact on fields as diverse as literature, film, Marxist and feminist theories, philosophy, and psychology. However, some of his theories remain controversial and disputed by numerous critics. One critic called him the "creator of a complex pseudo-science which should be recognized as one of the great follies of Western civilization".

Sigmund Freud was born on 6 May 1856 to Galician Jewish parents in Příbor (), Moravia, Austrian Empire, now Czech Republic. His father Jakob was 41, a wool merchant, and had two children by a previous marriage. His mother Amalié was 21. Owing to his intellect, which was obvious from an early stage of his childhood, his parents favoured him over his siblings, and even though they were poor they offered everything to give him a proper education. Due to the economic crisis of 1857, father Freud lost his business, and the family moved first to Leipzig, Germany before settling in Vienna, Austria. In 1865, Sigmund entered the Leopoldstädter Communal-Realgymnasium, a prominent high school. Freud was an outstanding pupil and graduated the Matura in 1873 with honors.

After planning to study law, Freud joined the medical faculty at University of Vienna to study under Darwinist Prof. Karl Claus. At that time, Eel life history was still unknown, and due to their mysterious origins and migrations, a racist association was often made between eels and Jews and Gypsies. In search for their male sex organs, Freud spent four weeks at the Austrian zoological research station in Trieste, dissecting hundreds of eels without finding more than his predecessors such as Simon von Syrski. In 1876, he published his first paper about "the testicles of eels" in the “Mitteilungen der österreichischen Akademie der Wissenschaften”, conceding that he could not solve the matter either. Frustrated by the lack of success which would have gained him fame, and disgusted by the blood and gore, Freud chose to change his course of study. Biographers like Siegfried Bernfeld wonder if and how this early episode was significant for his later work regarding hidden sexuality and frustrations.

In 1874, the concept of "psychodynamics" was proposed with the publication of Lectures on Physiology by German physiologist Ernst Wilhelm von Brücke who, in coordination with physicist Hermann von Helmholtz, one of the formulators of the first law of thermodynamics (conservation of energy), supposed that all living organisms are energy-systems also governed by this principle. During this year, at the University of Vienna, Brücke served as supervisor for first-year medical student Sigmund Freud who adopted this new “dynamic” physiology. In his Lectures on Physiology, Brücke set forth the radical view that the living organism is a dynamic system to which the laws of chemistry and physics apply. This was the starting point for Freud's dynamic psychology of the mind and its relation to the unconscious. The origins of Freud’s basic model, based on the fundamentals of chemistry and physics, according to John Bowlby, stems from Brücke, Meynert, Breuer, Helmholtz, and Herbart. In 1879, Freud interrupted his studies to complete his one year of obligatory military service, and in 1881 he received his Dr. med. (M.D.) with the thesis "Über das Rückenmark niederer Fischarten" (on the spinal cord of lower fish species).

Freud married Martha Bernays in 1886, after opening his own medical practice, specializing in neurology. After experimenting with hypnosis on his neurotic patients, Freud abandoned this form of treatment, in favor of a treatment where the patient talked through his or her problems. This came to be known as the "talking cure". (The term was initially coined by the patient Anna O. who was treated by Freud's colleague Josef Breuer.) The "talking cure" is widely seen as the basis of psychoanalysis.

Freud held the opinion (based on personal experience and observation) that sexual activity was incompatible with the accomplishing of any great work. Since he felt that the great work of creating and establishing psychotherapy was his destiny, he told his wife that they could no longer engage in sexual relations. Indeed from about the age of forty until his death Freud was absolutely celibate “in order to sublimate the libido for creative purposes,” according to his biographer Ernest Jones.

Nonetheless, there has been persistent gossip, which has always been staunchly denied by Freud loyalists, about the possibility that around this time a romantic liaison had blossomed between Freud and his sister-in-law, Minna Bernays, who had moved into Freud's apartment at 19 Berggasse in 1896. This rumour of an illicit relationship has been most notably propelled forward by Carl Jung, Freud's disciple and later his archrival, who had claimed that Miss Bernays had confessed the affair to him. (This claim was dismissed by Freudians as malice on Jung's part.) It has been suggested that the affair resulted in a pregnancy and subsequently an abortion for Miss Bernays. A hotel log dated August 13, 1898 seems to support the allegation of an affair.

In his 40s, Freud "had numerous psychosomatic disorders as well as exaggerated fears of dying and other phobias" (Corey 2001, p. 67). During this time Freud was involved in the task of exploring his own dreams, memories, and the dynamics of his personality development. During this self-analysis, he came to realize the hostility he felt towards his father (Jacob Freud), and "he also recalled his childhood sexual feelings for his mother (Amalia Freud), who was attractive, warm, and protective" (Corey 2001, p. 67). Corey (2001) considers this time of emotional difficulty to be the most creative time in Freud's life.

After the publication of Freud's books in 1900 and 1901, interest in his theories began to grow, and a circle of supporters developed in the following period. Freud often chose to disregard the criticisms of those who were skeptical of his theories, however, and even gained a few direct opponents as a result, the most famous being Carl Jung, who was originally in support of Freud's ideas.

Carl Jung, the Swiss psychotherapist, told a colleague about his first visit with Sigmund Freud in the year 1907. Jung had much that he wanted to talk about with Freud, and he spoke with intense animation for three whole hours. Finally Freud interrupted him and, to Jung's astonishment, proceeded to group the contents of Jung's monologue into several precise categories that enabled them to spend their remaining hours together in a more profitable give-and-take.

In 1930 Freud received the Goethe Prize in appreciation of his contribution to psychology and to German literary culture. Three years later the Nazis took control of Germany and Freud's books featured prominently amongst those burned by the Nazis. In March 1938, Nazi Germany annexed Austria in the Anschluss. This led to violent outbursts of anti-Semitism in Vienna, and Freud and his family received visits from the Gestapo. Freud decided to go into exile "to die in freedom". He and his family left Vienna in June 1938 and traveled to London.

A heavy cigar smoker, Freud endured more than 30 operations during his life due to mouth cancer. In September 1939 he prevailed on his doctor and friend Max Schur to assist him in suicide. After reading Balzac's La Peau de chagrin in a single sitting he said, "My dear Schur, you certainly remember our first talk. You promised me then not to forsake me when my time comes. Now it is nothing but torture and makes no sense any more." Schur administered three doses of morphine over many hours that resulted in Freud's death on September 23, 1939. Three days after his death, Freud's body was cremated at Golders Green Crematorium during a service attended by Austrian refugees, including the author Stefan Zweig. His ashes were later placed in the crematorium's columbarium. They rest in an ancient Greek urn which Freud had received as a present from Marie Bonaparte and which he had kept in his study in Vienna for many years. After Martha Freud's death in 1951, her ashes were also placed in that urn. Golders Green Crematorium has since also become the final resting place for Anna Freud and her lifelong friend Dorothy Burlingham, as well as for several other members of the Freud family.

Freud has been influential in two related but distinct ways. He simultaneously developed a theory of how the human mind is organized and operates internally, and how human behavior both conditions and results from this particular theoretical understanding. This led him to favor certain clinical techniques for attempting to help cure psychopathology.

Since neurology and psychiatry were not recognized as distinct medical fields at the time of Freud's training, the medical degree he obtained after studying for six years at the University of Vienna board certified him in both fields, although he is far more well-known for his work in the latter. As far as neurology went, Freud was an early researcher on the topic of neurophysiology, specifically cerebral palsy, which was then known as "cerebral paralysis." He published several medical papers on the topic, and showed that the disease existed far before other researchers in his day began to notice and study it. He also suggested that William Little, the man who first identified cerebral palsy, was wrong about lack of oxygen during the birth process being a cause. Instead, he suggested that complications in birth were only a symptom of the problem. It was not until the 1980s that Freud's speculations were confirmed by more modern research.

Freud hoped that his research would provide a solid scientific basis for his therapeutic technique. The goal of Freudian therapy, or psychoanalysis, was to bring to consciousness repressed thoughts and feelings. According to some of his successors, including his daughter Anna Freud, the goal of therapy is to allow the patient to develop a stronger ego; according to others, notably Jacques Lacan, the goal of therapy is to lead the analysand to a full acknowledgment of his or her inability to satisfy the most basic desires.

Classically, the bringing of unconscious thoughts and feelings to consciousness is brought about by encouraging the patient to talk in free association and to talk about dreams. Another important element of psychoanalysis is a relative lack of direct involvement on the part of the analyst, which is meant to encourage the patient to project thoughts and feelings onto the analyst. Through this process, transference, the patient can reenact and resolve repressed conflicts, especially childhood conflicts with (or about) parents.

The origin of Freud's early work with psychoanalysis can be linked to Joseph Breuer. Freud actually credits Breuer with the discovery of the psychoanalytical method. One case started this phenomenon that would shape the field of psychology for decades to come, the case of Anna O. In 1880 a young girl came to Breuer with symptoms of what was then called female hysteria. Anna O. was a highly intelligent 21-year-old woman. She presented with symptoms such as paralysis of the limbs, split personality and amnesia; today these symptoms are known as conversion disorder. After many doctors had given up and accused Anna O. of faking her symptoms, Breuer decided to treat her sympathetically, which he did with all of his patients. He started to hear her mumble words during what he called states of absence. Eventually Breuer started to recognize some of the words and wrote them down. He then hypnotized her and repeated the words to her; Breuer found out that the words were associated with her father's illness and death.

In the early 1890s Freud used a form of treatment based on the one that Breuer had described to him, modified by what he called his "pressure technique". The traditional story, based on Freud's later accounts of this period, is that as a result of his use of this procedure most of his patients in the mid-1890s reported early childhood sexual abuse. He believed these stories, but after having heard a patient tell the story about Freud's personal friend being the victimizer, Freud concluded that his patients were fantasizing the abuse scenes.

In 1896 Freud posited that the symptoms of 'hysteria' and obsessional neurosis derived from unconscious memories of sexual abuse in infancy, and claimed that he had uncovered such incidents for every single one of his current patients (one third of whom were men). However a close reading of his papers and letters from this period indicates that these patients did not report early childhood sexual abuse as he later claimed: rather, he arrived at his findings by analytically inferring the supposed incidents, using a procedure that was heavily dependent on the symbolic interpretation of somatic symptoms.

Freud was an early user and proponent of cocaine as a stimulant as well as analgesic. He wrote several articles on the antidepressant qualities of the drug and he was influenced by his friend and confidant Wilhelm Fliess, who recommended cocaine for the treatment of the "nasal reflex neurosis." Fliess operated on Freud and a number of Freud's patients whom he believed to be suffering from the disorder, including Emma Eckstein, whose surgery proved disastrous..

Freud felt that cocaine would work as a cure-all for many disorders and wrote a well-received paper, "On Coca," explaining its virtues. He prescribed it to his friend Ernst von Fleischl-Marxow to help him overcome a morphine addiction he had acquired while treating a disease of the nervous system. Freud also recommended it to many of his close family and friends. He narrowly missed out on obtaining scientific priority for discovering cocaine's anesthetic properties (of which Freud was aware but on which he had not written extensively), after Karl Koller, a colleague of Freud's in Vienna, presented a report to a medical society in 1884 outlining the ways in which cocaine could be used for delicate eye surgery. Freud was bruised by this, especially because this would turn out to be one of the few safe uses of cocaine, as reports of addiction and overdose began to filter in from many places in the world. Freud's medical reputation became somewhat tarnished because of this early ambition. Furthermore, Freud's friend Fleischl-Marxow developed an acute case of "cocaine psychosis" as a result of Freud's prescriptions and died a few years later. Freud felt great regret over these events, which later biographers have dubbed "The Cocaine Incident."

Perhaps the most significant contribution Freud made to Western thought was his argument for the existence of an unconscious mind. During the 19th century, the dominant trend in Western thought was positivism, which subscribed to the belief that people could ascertain real knowledge concerning themselves and their environment and judiciously exercise control over both. Freud, however, suggested that such declarations of free will are in fact delusions; that we are not entirely aware of what we think and often act for reasons that have little to do with our conscious thoughts.

The concept of the unconscious as proposed by Freud was considered by some to be groundbreaking in that he proposed that awareness existed in layers and that some thoughts occurred "below the surface." Nevertheless, as psychologist Jacques Van Rillaer, among others, pointed out, "contrary to what most people believe, the unconscious was not discovered by Freud. In 1890, when psychoanalysis was still unheard of, William James, in his monumental treatise on psychology, examined the way Schopenhauer, von Hartmann, Janet, Binet and others had used the term 'unconscious' and 'subconscious'". Boris Sidis, a Jewish Russian who escaped to the USA in 1887, and studied under William James, wrote The Psychology of Suggestion: A Research into the Subconscious Nature of Man and Society in 1898, followed by ten or more works over the next twenty five years on similar topics to the works of Freud.

Moreover, the historian of psychology Mark Altschule wrote: "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.", cited in Allen Esterson, Freud returns?</bgref> Freud's advance was not, then, to uncover the unconscious but to devise a method for systematically studying it .

Dreams, which he called the "royal road to the unconscious," provided the best access to our unconscious life and the best illustration of its "logic," which was different from the logic of conscious thought. Freud developed his first topology of the psyche in The Interpretation of Dreams (1899) in which he proposed the argument that the unconscious exists and described a method for gaining access to it. The preconscious was described as a layer between conscious and unconscious thought—that which we could access with a little effort. Thus for Freud, the ideals of the Enlightenment, positivism and rationalism, could be achieved through understanding, transforming, and mastering the unconscious, rather than through denying or repressing it.

Crucial to the operation of the unconscious is "repression." According to Freud, people often experience thoughts and feelings that are so painful that they cannot bear them. Such thoughts and feelings—and associated memories—could not, Freud argued, be banished from the mind, but could be banished from consciousness. Thus they come to constitute the unconscious. Although Freud later attempted to find patterns of repression among his patients in order to derive a general model of the mind, he also observed that individual patients repress different things. Moreover, Freud observed that the process of repression is itself a non-conscious act (in other words, it did not occur through people willing away certain thoughts or feelings). Freud supposed that what people repressed was in part determined by their unconscious. In other words, the unconscious was for Freud both a cause and effect of repression.

Later, Freud distinguished between three concepts of the unconscious: the descriptive unconscious, the dynamic unconscious, and the system unconscious. The descriptive unconscious referred to all those features of mental life of which people are not subjectively aware. The dynamic unconscious, a more specific construct, referred to mental processes and contents which are defensively removed from consciousness as a result of conflicting attitudes. The system unconscious denoted the idea that when mental processes are repressed, they become organized by principles different from those of the conscious mind, such as condensation and displacement.

Eventually, Freud abandoned the idea of the system unconscious, replacing it with the concept of the Ego, super-ego, and id (discussed below). Throughout his career, however, he retained the descriptive and dynamic conceptions of the unconscious.

Freud hoped to prove that his model was universally valid and thus turned to ancient mythology and contemporary ethnography for comparative material. Freud named his new theory the Oedipus complex after the famous Greek tragedy Oedipus Rex by Sophocles. “I found in myself a constant love for my mother, and jealousy of my father. I now consider this to be a universal event in childhood,” Freud said. Freud sought to anchor this pattern of development in the dynamics of the mind. Each stage is a progression into adult sexual maturity, characterized by a strong ego and the ability to delay gratification (cf. Three Essays on the Theory of Sexuality). He used the Oedipus conflict to point out how much he believed that people desire incest and must repress that desire. The Oedipus conflict was described as a state of psychosexual development and awareness. He also turned to anthropological studies of totemism and argued that totemism reflected a ritualized enactment of a tribal Oedipal conflict.

Freud originally posited childhood sexual abuse as a general explanation for the origin of neuroses, but he abandoned this so-called "seduction theory" as insufficiently explanatory, noting that he had found many cases in which apparent memories of childhood sexual abuse were based more on imagination than on real events. During the late 1890s Freud, who never abandoned his belief in the sexual etiology of neuroses, began to emphasize fantasies built around the Oedipus complex as the primary cause of hysteria and other neurotic symptoms. Despite this change in his explanatory model, Freud always recognized that some neurotics had been sexually abused by their fathers, and was quite explicit about discussing several patients whom he knew to have been abused.

Freud also believed that the libido developed in individuals by changing its object, a process codified by the concept of sublimation. He argued that humans are born "polymorphously perverse", meaning that any number of objects could be a source of pleasure. He further argued that, as humans develop, they become fixated on different and specific objects through their stages of development—first in the oral stage (exemplified by an infant's pleasure in nursing), then in the anal stage (exemplified by a toddler's pleasure in evacuating his or her bowels), then in the phallic stage. Freud argued that children then passed through a stage in which they fixated on the mother as a sexual object (known as the Oedipus Complex) but that the child eventually overcame and repressed this desire because of its taboo nature. (The lesser known Electra complex refers to such a fixation on the father.) The repressive or dormant latency stage of psychosexual development preceded the sexually mature genital stage of psychosexual development.

Freud's way of interpretation has been called phallocentric by many contemporary thinkers. This is because, for Freud, the unconscious always desires the phallus (penis). Males are afraid of castration - losing their phallus or masculinity to another male. Females always desire to have a phallus - an unfulfillable desire. Thus boys resent their fathers (fear of castration) and girls desire theirs. For Freud, desire is always defined in the negative term of lack - you always desire what you don't have or what you are not, and it is very unlikely that you will fulfill this desire. Thus his psychoanalysis treatment is meant to teach the patient to cope with his or her insatiable desires.

In his later work, Freud proposed that the psyche could be divided into three parts: Ego, super-ego, and id. Freud discussed this structural model of the mind in the 1920 essay Beyond the Pleasure Principle, and fully elaborated it in The Ego and the Id (1923), where he developed it as an alternative to his previous topographic schema (conscious, unconscious, preconscious).

Freud acknowledges that his use of the term Id (or the It) derives from the writings of Georg Grodeck. It is interesting to note that the term Id appears in the earliest writing of Boris Sidis, attributed to William James, as early as 1898.

Freud believed that humans were driven by two conflicting central desires: the life drive (Eros) (incorporating the sex drive) and the death drive (Thanatos). Freud's description of Eros, whose energy is known as libido, included all creative, life-producing drives. The death drive (or death instinct), whose energy is known as mortido, represented an urge inherent in all living things to return to a state of calm: in other words, an inorganic or dead state. He recognized Thanatos only in his later years and develops his theory on the death drive in Beyond the Pleasure Principle. Freud approaches the paradox between the life drives and the death drives by defining pleasure and unpleasure. According to Freud, unpleasure refers to stimulus that the body receives. (For example, excessive friction on the skin's surface produces a burning sensation; or, the bombardment of visual stimuli amidst rush hour traffic produces anxiety.) Conversely, pleasure is a result of a decrease in stimuli (for example, a calm environment the body enters after having been subjected to a hectic environment). If pleasure increases as stimuli decreases, then the ultimate experience of pleasure for Freud would be zero stimulus, or death. Given this proposition, Freud acknowledges the tendency for the unconscious to repeat unpleasurable experiences in order to desensitize, or deaden, the body. This compulsion to repeat unpleasurable experiences explains why traumatic nightmares occur in dreams, as nightmares seem to contradict Freud's earlier conception of dreams purely as a site of pleasure, fantasy, and desire. On the one hand, the life drives promote survival by avoiding extreme unpleasure and any threat to life. On the other hand, the death drive functions simultaneously toward extreme pleasure, which leads to death. Freud addresses the conceptual dualities of pleasure and unpleasure, as well as sex/life and death, in his discussions on masochism and sadomasochism. The tension between Eros and Thanatos represents a revolution in his manner of thinking. Some also refer to the death instinct as the Nirvana Principle.

It should be added that these ideas owe a great deal to both Arthur Schopenhauer and Friedrich Nietzsche. Schopenhauer's pessimistic philosophy, expounded in The World as Will and Representation, describes a renunciation of the will to live that corresponds on many levels with Freud's Death Drive. The life drive clearly owes much to Nietzsche's concept of the Dionysian in The Birth of Tragedy. Freud was an avid reader of both philosophers and acknowledged their influence.

Freud's theories and research methods were controversial during his life and still are so today, but few dispute his huge impact on psychologists and the academically inclined.

Most importantly, Freud popularized the "talking-cure"—an idea that a person could solve problems simply by talking over them, something that was almost unheard of in the 19th century. Even though many psychotherapists today tend to reject the specifics of Freud's theories, this basic mode of treatment comes largely from his work.

Most of Freud's specific theories—like his stages of psychosexual development—and especially his methodology, have fallen out of favor in modern experimental psychology.

Some psychotherapists, however, still follow an approximately Freudian system of treatment. Many more have modified his approach, or joined one of the schools that branched from his original theories (see Neo-Freudian). Still others reject his theories entirely, although their practice may still reflect his influence.

Psychoanalysis today maintains the same ambivalent relationship with medicine and academia that Freud experienced during his life.

While he saw himself as a scientist, Freud greatly admired Theodor Lipps, a philosopher and main supporter of the ideas of the subconscious and empathy. Freud's theories have had a tremendous impact on the humanities--especially on the Frankfurt school and critical theory. Freud's model of the mind is often criticized as an unsubstantiated challenge to the enlightenment model of rational agency, which was a key element of much modern philosophy.

; Rationality: While many enlightenment thinkers viewed rationality as both an unproblematic ideal and a defining feature of man , Freud's model of the mind drastically reduced the scope and power of reason. In Freud's view, reasoning occurs in the conscious mind--the ego--but this is only a small part of the whole. The mind also contains the hidden, irrational elements of id and superego, which lie outside of conscious control, drive behavior, and motivate conscious activities. As a result, these structures call into question humans' ability to act purely on the basis of reason, since lurking motives are also always at play. Moreover, this model of the mind makes rationality itself suspect, since it may be motivated by hidden urges or societal forces (e.g. defense mechanisms, where reasoning becomes "rationalizing").

; Transparency of Self: Freud challenged the idea of empiricists such as John Locke and David Hume that the workings of the mind can be understood by introspection. He considered many central aspects of a person remain radically inaccessible to the conscious mind (without the aid of psychotherapy).

Although Freud's theories were influential, they came under widespread criticism during his lifetime and afterward. A paper by Lydiard H. Horton, read in 1915 at a joint meeting of the American Psychological Association and the New York Academy of Sciences, called Freud's dream theory "dangerously inaccurate" and noted that "rank confabulations...appear to hold water, psychoanalytically" . The philosopher A. C. Grayling has said that "Philosophies that capture the imagination never wholly fade....But as to Freud's claims upon truth, the judgment of time seems to be running against him." Peter D. Kramer, a psychiatrist and faculty member of Brown Medical School, said "I'm afraid [Freud] doesn't hold up very well at all. It almost feels like a personal betrayal to say that. But every particular is wrong: the universality of the Oedipus complex, penis envy, infantile sexuality." A 2006 article in Newsweek magazine called him "history's most debunked doctor."

Freud's theories are often criticized for not being real science. This objection was raised by Karl Popper, who claimed that all proper scientific theories must be potentially falsifiable. Popper argued that no experiment or observation could ever falsify Freud's theories of psychology (e.g. someone who denies having an Oedipal complex is interpreted as repressing it), and thus they could not be considered scientific.

H. J. Eysenck claims that Freud 'set psychiatry back one hundred years', consistently mis-diagnosed his patients, fraudulently misrepresented case histories and that "what is true in Freud is not new and what is new in Freud is not true".

Mikkel Borch-Jacobsen claims that "The truth is that Freud knew from the very start that Fleischl, Anna O. and his 18 patients were not cured, and yet he did not hesitate to build grand theories on these non-existent foundations...he disguised fragments of his self-analysis as ‘objective’ cases, that he concealed his sources, that he conveniently antedated some of his analyses, that he sometimes attributed to his patients ‘free associations’ that he himself made up, that he inflated his therapeutic successes, that he slandered his opponents."http://www.lrb.co.uk/v22/n08/borc01_.html

Among adherents of Freudian thought, a frequently criticized aspect of Freud's belief system is his model of psychosexual development, including Freud's claim that infants are sexual beings. Others have accepted Freud's expanded notion of sexuality, but have argued that this pattern of development is not universal, nor necessary for the development of a healthy adult. Instead, they have emphasized the social and environmental sources of patterns of development. Moreover, they call attention to social dynamics Freud de-emphasized or ignored, such as class relations. This branch of Freudian critique owes a great deal to the work of Herbert Marcuse.

Freud has also come under fire from many feminist critics. Although Freud was an early champion of both sexual freedom and education for women (Freud, "Civilized Sexual Morality and Modern Nervousness"), some feminists have argued that at worst his views of women's sexual development set the progress of women in Western culture back decades, and that at best they lent themselves to the ideology of female inferiority. Believing as he did that women are a kind of mutilated male, who must learn to accept their "deformity" (the "lack" of a penis) and submit to some imagined biological imperative, he contributed to the vocabulary of misogyny. Terms such as "penis envy" and "castration anxiety" contributed to discouraging women from entering any field dominated by men, until the 1970s. Some of Freud's most criticized statements appear in his 'Fragment of Analysis' on Ida Bauer such as "This was surely just the situation to call up distinct feelings of sexual excitement in a girl of fourteen" in reference to Dora being kissed by a 'young man of prepossessing appearance' implying the passivity of female sexuality and his statement "I should without question consider a person hysterical in whom an occasion for sexual excitement elicited feelings that were preponderantly or exclusively unpleasurable"

On the other hand, feminist theorists such as Juliet Mitchell, Nancy Chodorow, Jessica Benjamin, Jane Gallop, and Jane Flax have argued that psychoanalytic theory is essentially related to the feminist project and must, like other theoretical traditions, be adapted by women to free it from vestiges of sexism. Freud's views are still being questioned by people concerned about women's equality. Another feminist who finds potential use of Freud's theories in the feminist movement is Shulamith Firestone. In "Freudianism: The Misguided Feminism", she discusses how Freudianism is essentially completely accurate, with the exception of one crucial detail: everywhere that Freud wrote "penis", the word should be replaced with "power".

Dr. Jurgen von Scheidt speculated that most of Freud's psychoanalytical theory was a byproduct of his cocaine use. Cocaine enhances dopaminergic neurotransmission increasing sexual interest and obsessive thinking. Chronic cocaine use can produce unusual thinking patterns due to the depletion of dopamine levels in the prefrontal cortex.

The area of biography has been especially contentious in the historiography of psychoanalysis, for two primary reasons: first, following his death, significant portions of his personal papers were for several decades made available only at the permission of his biological and intellectual heirs (his daughter, Anna Freud, was extremely protective of her father's reputation); second, much of the data and theory of Freudian psychoanalysis hinges upon the personal testimony of Freud himself, and so to challenge Freud's legitimacy or honesty has been seen by many as an attack on the roots of his enduring work.

The first biographies of Freud were written by Freud himself: his On the History of the Psychoanalytic Movement (1914) and An Autobiographical Study (1924) provided much of the basis for discussions by later biographers, including "debunkers" (as they contain a number of prominent omissions and potential misrepresentations). A few of the major biographies on Freud to come out over the 20th century were: *Helen Walker Puner, Freud: His Life and His Mind (1947) — Puner's "facts" were often shaky at best but she was remarkably insightful with regard to Freud's unanalyzed relationship to his mother, Amalia.

* Ernest Jones, The Life and Work of Sigmund Freud, 3 vols. (1953–1958) — the first "authorized" biography of Freud, made by one of his former students with the authorization and assistance of Anna Freud, with the hope of "dispelling the myths" from earlier biographies. Though this is the most comprehensive biography of Freud, Jones has been accused of writing more of a hagiography than a history of Freud. Among his questionable assertions, Jones diagnosed his own analyst, Ferenczi, as "psychotic." In the same breath, Jones also maligned Otto Rank, Ferenczi's close friend and Jones's most important rival for leadership of the movement in the 1920s. * Henri Ellenberger, The Discovery of the Unconscious (1970) — was the first book to, in a compelling way, attempt to situate Freud within the context of his time and intellectual thought, arguing that he was the intellectual heir of Franz Mesmer and that the genesis of his theory owed a large amount to the political context of turn of the 19th century Vienna. (Swiss link: http://fr.wikipedia.org/wiki/Henri_F._Ellenberger) * Frank Sulloway, Freud: Biologist of the Mind (1979) — Sulloway, one of the first professional/academic historians to write a biography of Freud, positioned Freud within the larger context of the history of science, arguing specifically that Freud was, in fact, a biologist in disguise (a "crypto-biologist", in Sulloway's terms), and sought to actively hide this. * Peter Gay, Freud: A Life for Our Time (New York: W. W. Norton & Company, 1988) — Gay's impressively scholarly work was published in part as a response to the anti-Freudian literature and the "Freud Wars" of the 1980s (see below). Gay's book is probably the best pro-Freud biography available, though he is not completely uncritical of his hero. His "Bibliographical Essay" at the end of the volume provides astute evaluations of the voluminous literature on Freud up to the mid-1980s. * Breger, Louis. "Freud: Darkness in the Midst of Vision." (New York: Wiley, 2000). Though written from a psychoanalytic point of view (the author is a former President of the Institute of Contemporary Psychoanalysis), this is a "warts and all" life of Sigmund Freud. It corrects, in the light of historical research of recent decades, many (though not quite all) of several disputed traditional historical accounts of events uncritically recycled by Peter Gay.

The creation of Freud biographies has itself even been written about at some length—see, for example, Elisabeth Young-Bruehl, "A History of Freud Biographies," in Discovering the History of Psychiatry, edited by Mark S. Micale and Roy Porter (Oxford University Press, 1994).
