  Why then have some recent scholars linked the two theories so closely? They certainly have done so. Weisheipl ([1980], p. 243), for example, describes the plurality of forms as “simply a logical consequence of” universal hylomorphism. And Zavalloni ([1951], p. 437, n. 61) likewise claims that universal hylomorphism necessarily implies plurality of forms, although he says the latter does not imply the  former.[24]
