There is no place in nature for extinction.

The gods and their tranquil abodes appear, which no winds disturb, nor clouds bedew with showers, nor does the white snow, hardened by frost, annoy them; the heaven, always pure, is without clouds, and smiles with pleasant light diffused.

Falling drops will at last wear away stone.

The first-beginnings of things cannot be distinguished by the eye.

Things stand apart so far and differ, that What's food for one is poison for another.

Under what law each thing was created, and how necessary it is for it to continue under this, and how it cannot annul the strong rules that govern its lifetime.

...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.
