 D.L.’s bibliography (iv 11–14) lists over 70 titles; nothing whatever of these has survived, even in the form of identifiable quotations in other authors. Reconstruction of Xenocrates’ views turns, as in the case of Speusippus, on Aristotle, and, again as in the case of Speusippus, this is made the more difficult by Aristotle’s frequent failure actually to name Xenocrates when talking about his views. In fact, Aristotle never mentions Xenocrates by name in discussing his metaphysical views.
