It was certainly not by design that the particles fell into order, they did not work out what they were going to do, but because many of them by many chances struck one another in the course of infinite time and encountered every possible form and movement, that they found at last the disposition they have, and that is how the universe was created.
LucretiusSince you must admit that there is nothing outside the universe, it can have no limit and is accordingly without end or measure. It makes no odds in which part of it you may take your stand; whatever spot anyone may occupy, the universe stretches away from him just the same in all directions without limit.
LucretiusThus the sum of things is ever being reviewed, and mortals dependent one upon another. Some nations increase, others diminish, and in a short space the generations of living creatures are changed and like runners pass on the torch of life.
Lucretius
