The highest possible stage in moral culture is when we recognize that we ought to control our thoughts.

As is the face, so is the mind.

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

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

Your mind’s got to eat, too.

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

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.

What is the hardest task in the world? To think.

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

The mind of man is capable of anything.

my mind is
a big hunk of irrevocable nothing

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

Brains are the only things worth having in this world.
