 Some features of this system are worth pointing out. First, as I have already noted, Aristotle gives pride of place in this scheme to primary substances. He says that were primary substances not to exist then no other entity would exist (2b6). As a result, Aristotle’s categorialism is firmly anti-Platonic. Whereas Plato treated the abstract as more real than material particulars, in the Categories Aristotle takes material particulars as ontological bedrock — to the extent that being a primary substance makes something more real than anything else, entities such as Socrates and a horse are the most real entities in Aristotle’s worldview. Moreover, among secondary substances, those at a lower level of generality are what Aristotle calls ‘prior in substance’ than those at a higher level (2b7). So, for instance, human is prior in substance than body. Whether this is to be interpreted in terms of the greater reality of the kind human is an open question. Nonetheless, Aristotle’s equating an increase in generality with a decrease in substantiality is at least in spirit strongly anti-Platonic.
