Abstract
Scotus’ mark on Suárez’s metaphysics can be perceived not only in his elaboration of intellectual knowledge of the singular, but also in the idea that prime matter is not pure potency, but possesses its own act, as well as in the thesis that states that the accident possesses too its own being. Of these two ideas, in addition to the tendency towards hypostatisation both regarding matter and accident, comes the breakdown of the unity of material substance both in the substantial and accidental planes, something that Suárez, in a way very similar to Scotus, tries to remedy by appealing to the modes of union. Lastly, a fundamental consequence of the hypostatisation of the accident is phenomenism, as seen in the works of authors such as Locke and Kant.
