Nature, they hold, aims both at utility and at pleasure, as is clear from the analogy of human craftsmanship. That all things happen by fate or destiny is maintained by Chrysippus in his treatise De fato, by Posidonius in his De fato, book ii., by Zeno and by Boëthus in his De fato, book i. Fate is defined as an endless chain of causation, whereby things are, or as the reason or formula by which the world goes on. What is more, they say that divination in all its forms is a real and substantial fact, if there is really Providence. And they prove it to be actually a science on the evidence of certain results: so Zeno, Chrysippus in the second book of his De divinatione, Athenodorus, and Posidonius in the second book of his Physical Discourse and the fifth book of his De divinatione. But Panaetius denies that divination has any real existence.
