Diotimus
5. A Stoic philosopher, who is said to have accused Epicurus of profligacy, and to have forged fifty letters, professing to have been written by Epicurus, to prove it. (Diog. Laet. 10.3; Menag. ad loc.) According to Athenaeus, who is evidently alluding to the same story in a passage where Δεότιμος apparently should be substituted for Θεότιμος, he was convicted of the forgery, at the suit of Zeno the Epicurean, and put to death. (Ath. xiii. p. 611b.) We learn from Clement of Alexandria (Strom. 2.21), that he considered happiness or well-being (εὐεστώ) to consist, not in any one good, but in the perfect accumulation of blessings (παντέλεια τῶν ἀγαθῶν), which looks like a departure from strict Stoicism to the more sober view of Aristotle. (Eth. Nicom. 1.7, 8.)
