This fifth volume of the Middle Works contains Ethics by John Dewey and his former colleague at the University of Michigan, James H. Tufts, which ap­peared as one of the last in the Holt American Science series of textbooks. Within some six months after publica­tion, Ethics was adopted as a textbook by thirty colleges. The book continued to be extremely popular and widely used, and was reprinted twenty-five times before both authors completely revised their respective parts for the new 1932 edition.

Up to the time Ethics was published, Dewey’s approach to ethics was known primarily from two short publications that were developed for use by his classes at the University of Michigan: Outlines of a Critical Theory of Ethics (1891) and The Study of Ethics: A Syl­labus (1894). Charles Stevenson notes in his Introduction to the present edition that Ethics afforded Dewey an opportu­nity to preserve and enrich the content of those earlier works and at the same time to expound his position in a more systematic manner.
