Naive Physics: An Essay in Ontology

In the works of Aristotle or of the medievals, as also in the writings of later common-sense philosophers such as Thomas Reid or G. E. Moore, we find a family of different attempts to come to grips with the structures of common sense and of the common-sense world that is given to us in normal, pre-theoretical experience. We shall argue in what follows that the theory of such structures provides an important and hitherto unappreciated link between early Gestalt psychology on the one hand and contemporary developments in philosophy and in artificial intelligence research on the other.
