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.
A world is a circumscribed portion of sky... it is a piece cut off from the infinite.
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.
The 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.
Death is nothing to us: for after our bodies have been dissolved by death they are without sensation, and that which lacks sensation is nothing to us. And therefore a right understanding of death makes mortality enjoyable, not because it adds to an infinite span of time, but because it takes away the craving for immortality.
