The real duty of man is not to extend his power or multiply his wealth beyond his needs, but to enrich and enjoy his imperishable possession: his soul.

He meant that when people laugh together, they cease to be young and old, master and pupils, jailer and prisoners. They become a single group of human beings enjoying its existence.

The art of invective resembles the art of boxing. Very few fights are won with the straight left. It is too obvious, and it can betoo easily countered. The best punches, like the best pieces of invective in this style, are either short-arm jabs, unexpectedly rapid and deadly; or else one-two blows, where you prepare your opponent with the first hit, and then, as his face comes forward, connect with your other fist: one, two. Both are effective; but they can be administered only by a real artist, with a real wish to knock his enemy out.
