As a result of a very fruitful dialectic resulting from the interchange of points of view at the Bellagio Conference, I now find myself in a position to extend my original remarks on the general notion of order in a considerable number of ways . ., On Metaphysics. I think the most important aspect of the interchange is the emergence of a common realization that metaphysics is fundamental to every branch of science. Metaphysics is not a well-defined field of study, a single, basic foundation on top of which we erect a towering structure of physics, chemistry, biology, psychology, sociology, and so on; but, rather, something that pervades every field, that conditions each person's thinking in varied and subtle ways, of which we are often not conscious.
