What is the wise man’s purpose in devoting himself to leisure? He knows that in leisure as well as in action he will accomplish something by which he will be of service to posterity. Our school at any rate declares that Zeno and Chrysippus have done greater things than they would have done had they been in command of armies, or filled high offices, or passed laws: which latter indeed they did pass, though not for one single state, but for the whole human race. How then can it be unbecoming to a good man to enjoy a leisure such as this, by whose means he gives laws to ages to come, and addresses himself not to a few persons but to all men of all nations, both now and hereafter? To sum up the matter, I ask you whether Cleanthes, Chrysippus, and Zeno lived in accordance with their doctrine? I am sure that you will answer that they lived in the manner in which they taught that men ought to live: yet no one of them governed a state.
