Men are more moral than they think and far more immoral than they can imagine.

Psycho-analysis has taught us that a boy's earliest choice of objects for his love is incestuous and that those objects are forbidden ones - his mother and his sister. We have learnt, too, the manner in which, as he grows up, he liberates himself from this incestuous attraction. A neurotic, on the other hand, invariably exhibits some degree of psychical infantilism. He has either failed to get free from the psychosexual conditions that prevailed in his childhood or he has returned to them - two possibilities which may be summed up as developmental inhibition and regression.

A collection to which nothing can be added and from which nothing can be removed is, in fact, dead!

Our possibilities of happiness are already restricted by our constitution. Unhappiness is much less difficult to experience. We are threatened with suffering from three directions: from our own body, which is doomed to decay and dissolution and which cannot even do without pain and anxiety as warning signals; from the external world, which may rage against us with overwhelming and merciless forces of destruction; and finally from our relations to other men. The suffering which comes from this last source is perhaps more painful to us than any other.
