Love your fellow creature, though vicious. Hate vice in the friend…

Praise your friends, and let your friends praise you.

Insult not another for his want of a talent you possess: He may have others which you want.

Do not endeavour to shine in all companies. Leave room for your hearers to imagine something within you beyond all you have said. And remember, the more you are praised, the more you will be envied.

If you mean to make your side of the argument appear plausible, do not prejudice the people against what you think truth by your passionate manner of defending it.

He who knows the world will not be too bashful. He who knows himself will not be impudent.

If you give a jest, take one. Let all your jokes be truly jokes. Jesting sometimes ends in sad earnest.
