There are infinite worlds both like and unlike this world of ours. For the atoms being infinite in number... are borne on far out into space.
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 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.
