Negative Forms in Plato's _Sophist_: A Re-Examination

Contrary to recent work on the topic, I argue that, in the Sophist, Plato's Visitor does not posit any negative kinds or forms, such as the kind or form of the not-beautiful or not-being. My argument has a textual and a philosophical side. On the textual side, I argue that the Visitor does not posit negative kinds or forms. On the philosophical side, I argue that the Visitor does not need to posit any such entities because he can reach his goals by appeal to difference. The latter conclusion suggests that an appeal to negative kinds or forms would be gratuitous and hence weaken the Visitor’s account. The textual result implies that we need not saddle him with this unsatisfactory view. Rather, by appeal to difference, the Visitor offers a unified account of ‘is not’ claims and false speech that relies on remarkably economical ontological resources.
