Categories and Predications

A categorical ontology is a general classification scheme arising from the analysis of the\r\nrelation of ontological predication. In the last decades, Lowe proposed a specific ontological\r\nsquare which combines the distinction between universals and particulars, based on a relation\r\nof essential predication, and the distinction between attributes and substrates, based on a relation\r\nof attributive predication. In this paper I briefly contrast Lowe’s square with the classical\r\nAristotelian square and argue that the framework proposed by Aristotle allows us to develop a\r\nbetter interpretation of the fundamental entities and relations that constitute the square.
