Cleanthes

Alden Cleanthes, the Virginia field organizer who set up the event, said the group chose Presidents Day because most children were off from school.

Like the earlier Stoics, Cleanthes and Chrysippus, he held that virtue may be taught.

This is the Zeus of the philosophers, of the Stoics, of Cleanthes: but he was already the Zeus of the ancient poets.

Chrysippus, however, restricted to the best and noblest souls this future existence, which Cleanthes had awarded to all,205 and among the Roman Stoics even this was greatly doubted.

To sum up; the end of man's being and his true happiness is what Zeno expressed as "living harmoniously," a statement which Cleanthes developed by adding the words "with Nature."
