Volume 4 of' The Early Works series covers the period of Dewey's last year and one-half at the University of Michigan and his first half-year at the University of Chicago. In addition to sixteen articles the present volume contains Dewey's reviews of six books and three articles, verbatim reports of three oral statements made by Dewey, and a full-length book, The Study of Ethics. Like its predecessors in this series, this volume presents a clear text, free of interpretive or reference material. Apparatus, including references, corrections, and emendations, is confined to appendix material. Fredson Bowers, the Consulting Textual Editor, has provided an essay on the textual principles and procedures, and Wayne A. R. Leys, Professor of Philosophy at Southern Illinois University, has written an Introduction discussing the relationship between Dewey's writings of this period and his later work. That Dewey's scholarship and writing was at an especially high level during 1893 and 1894 may be considered an index to the significance of this two-year period.
