Occamism differed from the other Scholastic schools on two major points: first, Occamism strongly argued position that only individuals exist, rather than supra-individual metaphysical universals, essences, or forms, and that universals are the products of abstraction from individuals by the human mind and have no extra-mental existence.[1] Second, Occamism denied the real existence of metaphysical universals and advocated the reduction of ontology.
