Sentimentality is a superstructure covering brutality.

It had become clear to me, in a flash of illumination, that for me the only possible goal was psychiatry. Here alone the two currents of my interest could flow together and in a united stream dig their own bed. Here was the empirical field common to biological and spiritual facts, which I had everywhere sought and nowhere found. Here at last was the place where the collision of nature and spirit became a reality.

Great talents are the most lovely and often the most dangerous fruits on the tree of humanity. They hang upon the most slender twigs that are easily snapped off.

Nothing is more repulsive than a furtively prurient spirituality; it is just as unsavoury as gross sensuality.

We cannot change anything unless we accept it.

Even a lie is a psychic fact.

Where love rules, there is no will to power; and where power predominates, there love is lacking. The one is the shadow of the other.
