I think the first wisdom is to restrain the tongue.

Consider in silence whatever any one says: speech both conceals and reveals the inner soul of man.

Don't promise twice what you can do at once.

Do not expect good from another's death.

Speak briefly and to the point.

Some have said that it is not the business of private men to meddle with government--a bold and dishonest saying, which is fit to come from no mouth but that of a tyrant or a slave. To say that private men have nothing to do with government is to say that private men have nothing to do with their own happiness or misery; that people ought not to concern themselves whether they be naked or clothed, fed or starved, deceived or instructed, protected or destroyed.

It is remarkable that men, when they differ in what they think considerable, will be apt to differ in almost everything else; their difference begets contradiction; contradiction begets heat; heat quickly rises into resentment, rage, and ill-will; thus they differ in affections, as they differ in judgment.
