Religion [is] the universal obsessional neurosis of humanity

Plaque was placed on 6 May 1977 at Bellevue (a house on the slopes of the Wienerwald) where the Freud family spent their summers.

The psychical, whatever its nature may be, is itself unconscious.

Properly speaking, the unconscious is the real psychic; its inner nature is just as unknown to us as the reality of the external world, and it is just as imperfectly reported to us through the data of consciousness as is the external world through the indications of our sensory organs.

Religious illusion must bow to scientific truth. It is in total error about the nature of the true world. Only science is not an illusion.

The state in which the ideas existed before being made conscious is called by us repression, and we assert that the force which instituted the repression and maintains it is perceived as resistance during the work of analysis.

Human life in common is only made possible when a majority comes together which is stronger than any separate individual and which remains united against all separate individuals. The power of this community is then set up as right in opposition to the power of the individual, which is condemned as brute force.
