[191] _Op. cit._, p. 39 f. Bradley suggests a similar idea of the 'tensional situation.' See, for instance, _Ethical Studies_, p. 65, where he remarks: "We have conflicting desires, say A and B; we feel two tensions, two drawings (so to speak) but we can not actually affirm ourselves in both." A more complete statement of the 'tensional situation' will be found on page 239 of the same work and in various other passages. [192] _Ibid._, pp. 43-44. [193] _Op. cit._, p. 45.

CHAPTER VII THE POLEMICAL PERIOD After the publication of the _Studies in Logical Theory_, Dewey entered upon what may be called the polemical period of his career. He joined forces with James and Schiller in the promotion of the new movement called 'Pragmatism.' The _Journal of Philosophy, Psychology, and Scientific Methods_, instituted at Columbia University in 1904, the same year in which Dewey accepted a professorship in that institution, became a convenient medium for the expression of his views, and every volume of this periodical will be found to contain notes, discussions, and articles by Dewey and his followers, bearing on current controversy. He also published many articles in other journals, technical and popular. In 1910, the most important of these essays were collected into a volume, published under the title, _The Influence of Darwin on Philosophy, and Other Essays_. For purposes of discussion, these essays may be divided into two classes: those of a more constructive character, setting forth Dewey's own standpoint, and those which are mainly polemical, directed against opposing standpoints, chiefly the idealistic. The constructive writings will be given first consideration. The essay on "The Postulate of Immediate Empiricism," first published in the _Journal of Philosophy, Psychology, and Scientific Methods_, in July, 1905, and later reprinted in the volume of collected essays, offers a convenient point of departure. Dewey observes that many of the difficulties in current controversy can be traced to presuppositions tacitly held by thinkers as to what experience means. Dewey attempts to make his own presuppositions explicit, with the object of clearing up this confusion.
