In this series of lectures, Dewey presents the metaphysics underlying his influential views on science, ethics, education, and social reform. His starting point is that existence is a mingling of the stable and predictable with the shifting and hazardous. The notion of causality has a practical basis, and science is concerned with bringing about preconceived ends. On this basis, Dewey develops his conception of the mind as a manifestation of social interactions, and expounds his distinctive views on the mind-body problem, esthetics, and values in general.
