With the exception of The Quest for Certainty (Volume 4) this fifth volume brings together Dewey's writings for the 1929-1930 period.
During this time Dewey published 4 books and 50 articles on philosophical, educational, political, and social issues. His philosophical essays include "What Humanism Means to Me" and "What I Believe," both of which express Dewey's faith in man's potentialities and intelligence, and a lively Journal of Philosophy exchange with Ernest Nagel, William Ernest Hocking, C. I. Lewis, and F. J. E. Woodbridge. Educational writings include The Sources of a Science of Education. The contents of this volume reflect Dewey's increasing involvement in social and political problems.
