my mind is
a big hunk of irrevocable nothing

Understanding is a very dull occupation.

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

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

Imagination continually outruns the creature it inhabits.

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

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

The real question is not whether machines think but whether men do.

Your mind’s got to eat, too.

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

There is no female mind. The brain is not an organ of sex. As well speak of a female liver.

Is there no way out of the mind?

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