Let no young man delay the study of philosophy, and let no old man become weary of it; for it is never too early nor too late to care for the well-being of the soul.

He who is not satisfied with a little, is satisfied with nothing .

Pleasure is the first good. It is the beginning of every choice and every aversion. It is the absence of pain in the body and of troubles in the soul.

The knowledge of sin is the beginning of salvation.

It is impossible for someone to dispel his fears about the most important matters if he doesn't know the nature of the universe but still gives some credence to myths. So without the study of nature there is no enjoyment of pure pleasure.

Pleasure is the beginning and the end of living happily. Epicurus taught: Pleasure, defined as freedom from pain, is the highest good.

The summit of pleasure is the elimination of all that gives pain.
