In his old age, he reportedly lapsed from the Stoic ideal and indulged in pleasure. "Eratosthenes the Cyrenean ... in his treatise which is entitled "Ariston," represents his master as subsequently being much addicted to luxury, speaking as follows: "And before now, I have at times discovered him breaking down, as it were, the partition wall between pleasure and virtue, and appearing on the side of pleasure." And Apollophanes (and he was an acquaintance of Ariston), in his "Ariston" (for he also wrote a book with that title), shows the way in which his master was addicted to pleasure."
