To laugh at men of sense is the privilege of fools. - Jean de La Bruyère

Profound ignorance makes a man dogmatical; he who knows nothing thinks he can teach others what he just now has learned himself; whilst he who knows a great deal can scarcely imagine any one should be unacquainted with what he says, and, therefore, speaks with more indifference.

A fool is always troublesome, a man of sense perceives when he pleases or is tiresome ; he goes away the very minute before it might have been thought he stayed too long.

To speak and to offend is with some people but one and the same thing; they are biting and bitter; their words are steeped in gall and wormwood; sneers as well as insolent and insulting words flow from their lips. It had been well for them had they been born mute or stupid; the little vivacity and intelligence they have prejudices them more than dullness does others; they are not always satisfied with giving sharp answers, they often attack arrogantly those who are present, and damage the reputation of those who are absent; they butt all round like rams — for rams, of course, must use their horns. We therefore do not expect, by our sketch of them, to change such coarse, restless, and stubborn individuals. The best thing a man can do is to take to his heels as soon as he perceives them, without even turning round to look behind him.
