Most ignorance is vincible ignorance. We don't know because we don't want to know.

Henry's universe was modeled on the highball. It was a mixture in which half a pint of the fizziest philosophical and scientific ideas all but drowned a small jigger of immediate experience, most of it strictly sexual. Broken reeds are seldom good mixers. They're far too busy with their ideas, their sensuality and their psychosomatic complaints to be able to take an interest in other people - even their own wives and children. They live in a state of the most profound voluntary ignorance, not knowing anything about anybody, but abounding in preconceived opinions about everything.

Most ignorance is vincible ignorance. We don't know because we don't want to know.

What a gulf between impression and expression! That’s our ironic fate—to have Shakespearean feelings and (unless by some billion-to-one chance we happen to be Shakespeare) to talk about them like automobile salesmen or teen-agers or college professors. We practice alchemy in reverse—touch gold and it turns into lead; touch the pure lyrics of experience, and they turn into the verbal equivalents of tripe and hogwash.

In spite of language, in spite of intelligence and intuition and sympathy, one can never really communicate anything to anybody. The essential substance of every thought and feeling remains incommunicable, locked up in the impenetrable strong-room of the individual soul and body. Our life is a sentence of perpetual solitary confinement.

There are things known and there are things unknown, and in between are the doors of perception.
