Leisure is one of the three greatest rewards of being a teacher. It is, unfortunately, the privilege which teachers most often misuse.

I believe that much of the maladjustment in our societies is caused, not by malevolence and corruption, but simply by ignorance.

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.
