The pleasant life is not produced by continual drinking and dancing, nor sexual intercourse, nor rare dishes of sea food and other delicacies of a luxurious table. On the contrary, it is produced by sober reasoning which examines the motives for every choice and avoidance, driving away beliefs which are the source of mental disturbances.
EpicurusThe 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.
EpicurusWe 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.
EpicurusThe things you really need are few and easy to come by; but the things you can imagine you need are infinite, and you will never be satisfied.
Epicurus
