I shall devote this paper mainly to asking questions. The questions I shall ask call for explanations, elucidations, of some of the crucial notions in Professor Chisholm's recent writings on ontology and the theory of intentionality. (He holds, in my opinion correctly, that these two branches of philosophy are inseparable.) An early version of Part I was read at a symposium held at the December 1982 meetings of the Eastern Division of the American Philosophical Association, as comments on Chisholm's "Converse Intentional Properties", which was one of the main papers. I thank Chisholm for his gracious and valuable replies but regret that I have not been able to accept all of them.
