John Buridan's Metaphysics of Persistence

John Buridan's theory of persistence is based on a metaphysical foundation that has been misrepresented by contemporary scholars. I argue that this fact is both (i) suggested by his treatment of persistence itself, and (ii) explicit in his clearest exposition of the foundations of persistence. I also argue that while this fact has historical interest, its primary interest is philosophical in nature: it shows Buridan developing a distinction that contemporary philosophers find useful in elaborating a metaphysical basis for theories of persistence.
