Religion belonged to the infancy of humanity. Now that humanity had come of age, it should be left behind.

Civilization runs a greater risk if we maintain our present attitude to religion than if we give it up.

Homosexuality is assuredly no advantage, but it is nothing to be ashamed of, no vice, no degradation; it cannot be classified as an illness; we consider it to be a variation of the sexual function, produced by a certain arrest of sexual development. Many highly respectable individuals of ancient and modern times have been homosexuals, several of the greatest men among them (Plato, Michelangelo, Leonardo da Vinci, etc.). It is a great injustice to persecute homosexuality as a crime--and a cruelty, too. If you do not believe me, read the books of Havelock Ellis.

One feels inclined to say that the intention that man should be 'happy' is not included in the plan of Creation.' . . . We are so made that we can derive intense enjoyment only from a contrast and very little from a state of things.

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

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... If one attempts to assign to religion its place in man's evolution, it seems not so much to be a lasting acquisition, as a parallel to the neurosis which the civilized individual must pass through on his way from childhood to maturity.

When inspiration does not come to me, I go halfway to meet it.
