The brain is an unreliable organ, it is monstrously great, monstrously developed. Swollen, like a goiter.

What a torture to talk to filled heads that allow nothing from the outside to enter them.

What is outside my mind means nothing to it.

Madness need not be all breakdown. It may also be breakthrough.

my mind is
a big hunk of irrevocable nothing

The mind of man is capable of anything.

A mind lively and at ease can do with seeing nothing, and can see nothing that does not answer.

In psychoanalysis nothing is true except the exaggerations.

Don’t lose your mind unless you have paid for it.

The sleep of reason produces monsters.

From a man’s face, I can read his character. If I can see him walk, I know his thoughts.

Brains are the only things worth having in this world.
