Dr. Dewey’s world, it seems to me, is one in which human beings occupy the imagination; the cosmos of astronomy, though of course acknowledged to exist, is at most times ignored. His philosophy is a power philosophy, though not, like Nietzsche’s, a philosophy of individual power; it is the power of the community that is felt to be valuable. It is this element of social power that seems to me to make the philosophy of instrumentalism attractive to those who are more impressed by our new control over natural forces than by the limitations to which that control is still subject.
