  But other authors rejected these two views. The best known is no doubt Thomas Aquinas. Aquinas held that the uniqueness of God's absolute simplicity does not require positing a kind of matter in all creatures. Rather all creatures, including incorporeal substances such as angels or human souls, are composite insofar as they have a composition of essence and esse (“to be,” the act of existing), whether or not they have an additional composition or matter and  form.[17]  Again, he argues that if any substance has a plurality of forms, only the first form that comes to it can be a substantial form; all the others must be accidental  forms.[18]  Godfrey of Fontaines likewise rejected both theories. John Duns Scotus accepted plurality of forms, but denied universal  hylomorphism.[19]
