Forbear to spew out reason from your mind, but rather ponder everything with keen judgment; and if it seems true, own yourself vanquished, but, if it is false, gird up your loins to fight.
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.
LucretiusOne thing is made of another, and nature allows no new creation except at the price of death.
