Do not spoil what you have by desiring what you have not.

If thou wilt make a man happy, add not unto his riches but take away from his desires.

Without confidence, there is no friendship.

Riches do not exhilarate us so much with their possession as they torment us with their loss.

Pleasure is our first and kindred good. It is the starting point of every choice and of every aversion, and to it we always come back, inasmuch as we make feeling the rule by which to judge of every good thing.

When someone admits one and rejects another which is equally in accordance with the appearances, it is clear that he has quitted all physical explanation and descended into myth.

The noble soul occupies itself with wisdom and friendship.
