Wise people are in want of nothing, and yet need many things. On the other hand, nothing is needed by fools, for they do not understand how to use anything, but are in want of everything

Chrysippus

Chryssipus was the pupil of Cleanthes and the glue that held Stoicism together. He was considered one of the brightest minds of his time. Chryssipus is responsible for consolidating and elaborating the teachings of Zeno and Cleanthes into the Stoic system that would survive for over two thousand years. The historian Diogenes said, without Chryssipus, there would be no Stoicism.
