Abstract

This article is a contribution to what we might call „commonsense-ontology“. The aim is to defend the commonsensical distinction between living beings and artefacts on the basis of ontological arguments. The distinction between living beings and artefacts is increasingly difficult to draw because of new developments in biotechnology. For developing criteria of an acceptable distinction I defend the existence of artefacts first. Subsequently I discuss three criteria how we might sensibly distinguish between living beings and artefacts. These criteria are metabolism, active powers and the capacity to develop. In this context I rely on the ontological distinction between unity and whole.
