Happiness is man's greatest aim in life. Tranquility and rationality are the cornerstones of happiness.
EpicurusIt is possible to provide security against other ills, but as far as death is concerned, we men live in a city without walls.
EpicurusMoreover, 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.
