Certainly it was no design of the atoms to place themselves in a particular order, nor did they decide what motions each should have. But atoms were struck with blows in many ways and carried along by their own weight from infinite times up to the present. They have been accustomed to move and to meet in all manner of ways. For this reason, it came to pass that being spread abroad through a vast time and trying every sort of combination and motion, at length those come together that produce great things, like earth and sea and sky and the generation of living creatures.
LucretiusSome species increase, others diminish, and in a short space the generations of living creatures are changed and, like runners, pass on the torch of life.
LucretiusPleasant it is, when over a great sea the winds trouble the waters, to gaze from shore upon another's great tribulation: not because any man's troubles are a delectable joy, but because to perceive from what ills you are free yourself is pleasant.
Lucretius
