FORMERLY FELLOW IN THE SAGE SCHOOL OF PHILOSOPHY A THESIS PRESENTED TO THE FACULTY OF THE GRADUATE SCHOOL OF CORNELL UNIVERSITY IN PARTIAL FULFILMENT OF THE REQUIREMENTS FOR THE DEGREE OF DOCTOR OF PHILOSOPHY NEW YORK LONGMANS, GREEN, & CO. 1919 PRESS OF THE NEW ERA PRINTING COMPANY LANCASTER, PA. PREFACE It seems unnecessary to offer an apology for an historical treatment of Professor Dewey's logical theories, since functionalism glories in the genetic method. To be sure, certain more extreme radicals are opposed to a genetic interpretation of the history of human thought, but this is inconsistent. At any rate, the historical method employed in the following study may escape censure by reason of its simple character, for it is little more than a critical review of Professor Dewey's writings in their historical order, with no discussion of influences and connections, and with little insistence upon rigid lines of development. It is proposed to "follow the lead of the subject-matter" as far as possible; to discover what topics interested Professor Dewey, how he dealt with them, and what conclusions he arrived at. This plan has an especial advantage when applied to a body of doctrine which, like Professor Dewey's, does not possess a systematic form of its own, since it avoids the distortion which a more rigid method would be apt to produce. It has not been possible, within the limits of the present study, to take note of all of Professor Dewey's writings, and no reference has been made to some which are of undoubted interest and importance. Among these may be mentioned especially his books and papers on educational topics and a number of his ethical writings. Attention has been devoted almost exclusively to those writings which have some important bearing upon his logical theory. The division into chapters is partly arbitrary, although the periods indicated are quite clearly marked by the different directions which Professor Dewey's interests took from time to time. It will be seen that there is considerable chance for error in distinguishing between the important and the unimportant, and in selecting the essays which lie in the natural line of the author's development. But, _valeat quantum_, as William James would say.
