Particular and Universal in Isagoge

Abstract

Porphyry's work titled Isagoge is commonly seen as an analysis of Aristotle's Categories, focusing on universal concepts, with the five predicables considered as different types of universals. Often, the same view is ascribed to Aristotle, but in fact, it is an approach arising from a confusion between universal and whole, as well as a confusion between particular and part by Porphyry in the Isagoge. In Categories, Aristotle does not refer to "whole" and "part" as synonyms for "universal" and "particular. Porphyry, however, in some cases distorting this distinction, uses “whole” and “part” to mean “universal” and “particular”. Moreover, they disagree on the essence of the five predicables and their relation to the universal. Aristotle views genes and species as universals and their connection to individuals as universal to particular, but he distinguishes them from the concept of universal and does not believe every universal is a genes or species. Porphyry, on the other hand, reduces genes and species to mere universal conceptions and consider them as synonyms for universal. It appears that there are two approachs in the philosophical tradition that started with Porphyry. These approachs were perpetuated and broadened by later thinkers. Initially, he altered the understanding of whole and part to universal and particular. Furthermore, he reduced genes and species to mere universal.
