During the three years embraced by Volume 7, Dewey published twenty articles and reviews, one of the articles of monograph-length, “The Psychology of Social Behavior,” one small book, Interest and Effort in Education, and sev­enty encyclopedia articles.

A salient and arresting feature of the essays is the continuing polemic be­tween Dewey and some of his critics. Ralph Ross, whose perceptive Introduc­tion to the volume provides a broad per­spective of the various philosophical controversies in which Dewey was en­gaged, comments that “when Dewey was pitting himself against important adversaries, his talents as a critic were fully evident.”
