Abstract

The essay deals with some aspects of Aristotle's second substances and of Aristotle's universals; the ontological status of second substances and of universals opposes the characteristics of the ideas; these characteristics are presented in the arguments of Aristotle's lost work On Ideas. The ontological presuppositions of the third man arguments are taken into examination. Aristotle's construction of a typological ontology is analyzed; the typological ontology builds the only possibility of obtaining a correct ontology. The ontological position of first substances in the Categories as entities which are numerical ones is described; the ontological position of second substances and universals as suches is explained. The differentiation of entities in individuals and universals is then taken into consideration. The implications of the attribute of the being separated and the contradictions which are involved in the attribution of being separated to universals complete the essay.
