Abstract

This paper suggests that within Aristotle’s well-known contribution to the history of ontology two different levels should be kept apart, an analytic-critical and a constructive level. On the first level Aristotle mainly provides analytic-critical tools for overcoming the main problems of all dealings with the notions of being and to be, while the second level consists in Aristotle’s ambitious project of conducting first philosophy (i.e. the specific part of his philosophy that is meant to continue the old and time-honoured project of identifying what Aristotle calls ‘first principles and causes’) as ontology, i.e. as an inquiry into being qua being.
