The word is the shadow of the deed.

Nothing exists but atoms and the void.

More men have become great through practice than by nature.

Nature and education are somewhat similar. The latter transforms man, and in so doing creates a second nature.

Everywhere man blames nature and fate yet his fate is mostly but the echo of his character and passion, his mistakes and his weaknesses.

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.

The animal needing something knows how much it needs, the man does not.
