Where life is possible at all, a right life is possible; life in a palace is possible; therefore even in a palace a right life is possible.

We ought to do good to others as simply as a horse runs, or a bee makes honey, or a vine bears grapes season after season without thinking of the grapes it has borne.

Retire into thyself. The rational principle which rules has this nature, that it is content with itself when it does what is just, and so secures tranquility.

The first rule is to keep an untroubled spirit. The second is to look things in the face and know them for what they are.

They know not how many things are signified by the words stealing, sowing, buying, keeping quiet, seeing what ought to be done; for this is not effected by the eyes, but by another kind of vision.

A rational nature admits of nothing but what is serviceable to the rest of mankind.

Be tolerant with others and strict with yourself.
