Without confidence, there is no friendship.

We begin every act of choice and avoidance from pleasure, and it is to pleasure that we return using our experience of pleasure as the criterion of every good thing.

Those desires that do not bring pain if they are not satisfied are not necessary; and they are easily thrust aside whenever to satisfy them appears difficult or likely to cause injury.

The term "incorporeal" is properly applied only to the void, which cannot act or be acted on. Since the soul can act and be acted upon, it is corporeal.

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.

Let no one be slow to seek wisdom when he is young nor weary in the search of it when he has grown old. For no age is too early or too late for the health of the soul.

Most men are in a coma when they are at rest and mad when they act.
