ABSTRACT In this article, I argue that an essential part of our obligation as teachers and scholars of philosophy is to insist that the ultimate point of criticism is to foster the development of increasingly better explanations of natural and social phenomena. Doing so, moreover, requires that we cultivate in ourselves and our students a sense of gratitude for the very possibility of human flourishing and scientific advance. I illustrate these claims by showing how Dewey's analysis in Human Nature and (...) Conduct is the sine qua non of a good explanation. (shrink)
