There is small disproportion betwixt a fool who useth not wit because he hath it not and him that useth it not when it should avail him.

Brevity is the soul of wit.

I was young and foolish then; now I am old and foolisher.

The stern compression of circumstances, the twinges of adversity, the spur of slights and taunts in early years, are needed to evoke that ruthless fixity of purpose and tenacious wit without which great actions are seldom accomplished.

A fool's brain digests philosophy into folly, science into superstition, and art into pedantry. Hence University education.

Humor is kindly. Wit is caustic.
