Aristoteles 2002

The essay surveys recent developments in ontology and defends a strategy for improvement of ontologies based on ontological realism. As a thought experiment, we consider central theses of Aristotelian metaphysics, and show how they fall short of what we believe to be the requirements of ontology today. Above all, Aristotle provides us with no strategy for the reconciliation of common-sense realism and scientific realism where these diverge. We focus specifically on shortfalls in Aristotle’s treatment of individual accidents, especially in regard to the category of place. We then show how Aristotle’s metaphysics needs to be supplemented by a theory of holes, of fiat boundaries, of granularity, and of vagueness.
