my mind is
a big hunk of irrevocable nothing

Any man could, if he were so inclined, be the sculptor of his own brain.

Imagination is the secret and marrow of civilization. It is the very eye of faith.

Is there no way out of the mind?

It is far, far better and much safer to have a firm anchor in nonsense than to put out on the troubled seas of thought.

The universe is an object of thought at least as much as it is a means of satisfying needs.

Though this be madness, yet there is method in’t.

Strength of mind is exercise, not rest.

Brains are the only things worth having in this world.

What the brain does by itself is infinitely more fascinating and complex than any response it can make to chemical stimulation.

If anything affects your eye, you hasten to have it removed; if anything affects your mind, you postpone the cure for a year.

The mind of man is capable of anything.

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