In doing nothing men learn to do evil.

Good-breeding is the art of showing men, by external signs, the internal regard we have for them. It arises from good sense, improved by conversing with good company.

Should anyone attempt to deceive you by false expressions, and not be a true friend at heart, act in the same manner, and thus art will defeat art. [If you would catch a man let him think he is catching you.]

In conversation avoid the extremes of forwardness and reserve.

The best way to keep good acts in memory is to refresh them with new.

I would not be beholden to a tyrant, for his acts of tyranny. For it is but usurpation in him to save, as their rightful lord, the lives of men over whom he has no title to reign.

The primary virtue is: hold your tongue; who knows how to keep quiet is close to God.
