 Plutarch claims (De communibus notitiis adversus Stoicos 1069e–f) that Xenocrates made happiness turn on living in accordance with nature; since this may derive from Antiochus of Ascalon, whose project it was to assimilate the Academy to Stoicism, it is suspect. Clement (Stromateis II 22) ascribes to him the view that happiness is the possession of one’s own excellence in the soul. This view bears a family resemblance to Aristotle’s (NE I 7. 1098a16–17, 9. 1099b26). The negative emphasis in Xenocrates’ evaluation of philosophical activity as “stopping the disturbance of the affairs of life” ([Galen], Historia philosophiae 8, in Diels 1879 605.7–8) sounds like a step in the direction of the Hellenistic goal of undisturbedness.
