Moreover, the universe as a whole is infinite, for whatever is limited has an outermost edge to limit it, and such an edge is defined by something beyond. Since the universe has no edge, it has no limit; and since it lacks a limit, it is infinite and unbounded. Moreover, the universe is infinite both in the number of its atoms and in the extent of its void.
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.
