With regard to excellence, it is not enough to know, but we must try to have and use it.

Piety requires us to honor truth above our friends.

For the things we have to learn before we can do them, we learn by doing them.

It is possible to fail in many ways…while to succeed is possible only in one way.

We must as second best…take the least of the evils.

Without friends no one would choose to live, though he had all other goods.
