Nothing exists except atoms and empty space; everything else is opinion.

If you would know contentment, let your deeds be few.

We think there is color, we think there is sweet, we think there is bitter, but in reality there are atoms and a void.

All things happen by virtue of necessity.

Nothing exists but atoms and the void.

There are innumerable worlds of different sizes. In some there is neither sun not moon, in others they are larger than in ours and others have more than one. These worlds are at irregular distances, more in one direction and less in another, and some are flourishing, others declining. Here they come into being, there they die, and they are distroyed by collision with one another. Some of the worlds have no animal or vegetable life nor any water.

Happiness does not reside in strength or money; it lies in rightness and many-sidedness.
