Being a blockhead is sometimes the best security against being cheated by a man of wit.

The sure way to be cheated is to think one's self more cunning than others.

There is no better proof of a man's being truly good than his desiring to be constantly under the observation of good men.

Conceit contributes more to conversation than wit.

Ridicule dishonors a man more than dishonor does.

It is a great act of cleverness to be able to conceal one's being clever.
