Who has a daring eye tell downright truths and downright lies.

Trust him not with your secrets, who, when left alone in your room, turns over your papers.

A sneer is often the sign of heartless malignity.

Who in the same given time can produce more than others has vigor; who can produce more and better, has talents; who can produce what none else can, has genius.

He who is passionate and hasty is generally honest. It is your cool, dissembling hypocrite of whom you should beware.

It is a poor wit who lives by borrowing the words, decisions, mien, inventions and actions of others.

True philosophy is that which renders us to ourselves, and all others who surround us, better, and at the same time more content, more patient, more calm and more ready for all decent and pure enjoyment.
