Apollodorus says, "If any one were to take away from the books of Chrysippus all the passages which he quotes from other authors, his paper would be left empty."

But Chrysippus, Posidonius, Zeno, and Boëthus say, that all things are produced by fate. And fate is a connected cause of existing things, or the reason according to which the world is regulated.

They also say that God is an animal immortal, rational, perfect, and intellectual in his happiness, unsusceptible of any kind of evil, having a foreknowledge of the universe and of all that is in the universe; however, that he has not the figure of a man; and that he is the creator of the universe, and as it were the Father of all things in common, and that a portion of him pervades everything.

The Stoics also teach that God is unity, and that he is called Mind and Fate and Jupiter, and by many other names besides.

One ought to seek out virtue for its own sake, without being influenced by fear or hope, or by any external influence. Moreover, that in that does happiness consist.

They say that the first inclination which an animal has is to protect itself.

When Zeno was asked what a friend was, he replied, "Another I."

Diogenes said once to a person who was showing him a dial, "It is a very useful thing to save a man from being too late for supper."

When a man reproached him for going into unclean places, he said, "The sun too penetrates into privies, but is not polluted by them."

Asked from what country he came, he replied, "I am a citizen of the world."
