 There are a total of twenty-five such citations in Athenaeus. Most simply record that Speusippus said one organism was like another (as with the last two), or simply record differences of terminology that happened to catch Athenaeus’ eye (as with the second one). The only one that promises anything more is the first one above, and that hardly promises much. But it has been supposed (see Tarán 1981) that it implies that Speusippus differentiated species of animals on the basis of features that would not have counted as differentiae in Aristotle’s way of classifying animals: differences of locale. And it is certainly possible that Speusippus’ holism involved a rejection of Aristotle’s essence-accident distinction: if we take the text quoted above from Aristotle as implying that someone who knows marshworts must know every respect in which they are like or unlike every other organism in the universe, and every such differentiating feature is as good as any other in defining them, then we have abandoned the project of differentiating organisms as it appeared to Aristotle.
