Sigmund Freud - Wikipedia

Religious doctrines … are all illusions, they do not admit of proof, and no one can be compelled to consider them as true or to believe in them.”

- Sigmund Freud in “The Future of an Illusion” (1927)

If the truth of religious doctrines is dependent on an inner experience that bears witness to the truth, what is one to make of the many people who do not have that experience? A poor girl may have an illusion that a prince will come and fetch her home. It is possible, some such cases have occurred. That the Messiah will come and found a golden age is much less probable."

- Sigmund Freud in “The Future of an Illusion” (1927)

Immorality, no less than morality, has at all times found support in religion.”

- Sigmund Freud in “The Future of an Illusion” (1927)

Our knowledge of the historical worth of certain religious doctrines increases our respect for them, but does not invalidate our proposal that they should cease to be put forward as the reasons for the precepts of civilization. On the contrary! Those historical residues have helped us to view religious teachings, as it were, as neurotic relics, and we may now argue that the time has probably come, as it does in an analytic treatment, for replacing the effects of repression by the results of the rational operation of the intellect. “

- Sigmund Freud in “The Future of an Illusion” (1927)

The true believer is in a high degree protected against the danger of certain neurotic afflictions, by accepting the universal neorosis he is spared the task of forming a personal neurosis.”

Sigmund Freud in “Civilization and Its Discontents” (1929)

One feels inclined to say that the intention that man should be "happy" is not included in the plan of "Creation."

Sigmund Freud in “Civilization and Its Discontents” (1929)

It is always possible to bind together a considerable number of people in love, so long as there are other people left over to receive manifestations of their aggressiveness.”

Sigmund Freud in “Civilization and Its Discontents” (1929)

Religion is an attempt to get control over the sensory world, in which we are placed, by means of the wish-world, which we have developed inside us as a result of biological and psychological necessities.”

Sigmund Freud in “A Philosophy of Life (Lecture 35)

Religion is an illusion and it derives its strength from the fact that it falls in with our instinctual desires."

- Sigmund Freud in “A Philosophy of Life” (Lecture 35)

What progress we are making. In the Middle Ages they would have burned me. Now they are content with burning my books.”

- Sigmund Freud in a letter to Ernest Jones (1933)

The Mosaic religion had been a Father religion; Christianity became a Son religion. The old God, the Father, took second place; Christ, the Son, stood in His stead, just as in those dark times every son had longed to do.”

- Sigmund Freud in “Moses and Monotheism” (1938)

"Sigmund Freud (German pronunciation: [ˈziːkmʊnt ˈfʁɔʏt]), born Sigismund Schlomo Freud (6 May 1856 – 23 September 1939), was an Austrian neurologist who founded the discipline of psychoanalysis. Freud is best known for his theories of the unconscious mind and the mechanism of repression, and for creating the clinical method of psychoanalysis for investigating the mind and treating psychopathology through dialogue between a patient (or "analysand") and a psychoanalyst.
Freud established sexual drives as the primary motivational forces of human life, developed therapeutic techniques such as the use of free association, discovered the phenomenon of transference in the therapeutic relationship and established its central role in the analytic process; he interpreted dreams as sources of insight into unconscious desires. He was an early neurological researcher into cerebral palsy, aphasia and microscopic neuroanatomy, and a prolific essayist, drawing on psychoanalysis to contribute to the history, interpretation and critique of culture."
