Abstract

Typically, Aristotle’s notion of an accidental unity is explained using our concept of identity, but doing so is fraught and liable to mislead. I argue that we should explain accidental unities in terms of sameness: doing so not only shows a coherence among texts thought to be in tension with one another, it reconciles the two competing conceptions of accidental unities in a satisfying way. I conclude by answering several Boolean questions that naturally arise in response to the inclusion of accidental unities in Aristotle’s ontology.
