By 1907, the first of the three years embraced by Volume 4, Dewey had abandoned thoughts of a possible career in the administration of higher education and was firmly established as a leading member of the Department of Philosophy at Columbia. As Lewis Hahn points out in his Introduction, these were very productive years for Dewey. In addition to numerous lectures and speaking engagements and participation in professional meetings, he published fifteen or so substantial articles, almost as many shorter things, a syllabus on "The Pragmatic Movement of Contemporary Thought, "a monograph on "Moral Principles in Education, "and, with J. H. Tufts, the first edition of a very popular textbook, "Ethics." "
