Fear is the mother of all gods ... Nature does all things spontaneously, by herself, without the meddling of the gods.

Huts they made then, and fire, and skins for clothing, And a woman yielded to one man in wedlock... ... Common, to see the offspring they had made; The human race began to mellow then. Because of fire their shivering forms no longer Could bear the cold beneath the covering sky.

One thing is made of another, and nature allows no new creation except at the price of death.

Since 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.

How is it that the sky feeds the stars?

Not they who reject the gods are profane, but those who accept them.

...if one thing frightens people, it is that so much happens, on earth and out in space, the reasons for which seem somehow to escape them, and they fill in the gap by putting it down to the gods.
