The mind of man is capable of anything.

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

Every thought is, strictly speaking, an afterthought.

The march of the human mind is slow.

The brain may be regarded as a kind of parasite of the organism, a pensioner, as it were, who dwells with the body.

Understanding is a very dull occupation.

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

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

Is there no way out of the mind?

As is the face, so is the mind.

Sooner or later if the activity of the mind is restricted anywhere, it will cease to function even where it is allowed to be free.

The human mind is an evolutionary product, just like the human body.

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