 Anna Marmodoro (2013) argues that the modern hylomorphists have misunderstood Aristotle in a radical fashion, in a way that is directly connected with their concern about the unity and hence reality of composites. She claims, with strong backing from the text, that form is not structure, because it is not a combination of parts. The essence of form is its unity, and its unity depends essentially on the fact that the matter that comes to compose it loses its previous identity. By contrast, in any kind of structure of parts this identity is not lost; the parts are merely organised in a certain way.
