James istic of his quick response to every sort of nov- elty and idealism. He was deeply moved not only by the human suffering and heroism which the earthquake of 1906 occasioned in California, but by the earthquake itself,—a new variety of experience, to be relished and described (Mem- ories and Studies). During the years 1904 and 1905, he published the remarkable series of arti- cles which he designed as parts of a larger work and which was brought together after his death under the title, Essays in Radical Empiricism (1912). James was prepared to take reality for what it appeared to be, even when this ran counter to the usual philosophical bias. In this sense his pluralism and "tychism" were radical, as manifesting a willingness to accept the prima jade multiplicity and waywardness of things de- spite their offense to the philosophic norms of unity and order. His empiricism was radical, in the second place, in its rigorous adherence to the maxim that things shall be assumed to be what they are experienced as] the effect of this maxim being the exclusion from existence of all substances, unknowables, and abstractions. Thirdly, James's empiricism was radical in the more positive and fruitful sense of finding expe- rience to be richer and philosophically more ade- quate than was customarily supposed. Thus ex- perience itself provides conjunctions as well as disjunctions, and does not need to be pieced out by a Kantian apparatus of intellectual forms; it is structurally self-sufficient, and does not need to be supported by a metaphysical substructure or frame such as the "Absolute" of the idealists. Finally, experience is more fundamental than either mind or matter, and provides the common measure in terms of which this duality can be understood and overcome. Consciousness is not an entity but a kind of relationship. The terms which enter into it are the same as those which in other relationships compose the so-called physical world. This view, set forth in the essay, "Does 'Consciousness* Exist?" (Journal of Philosophy, Psychology and Scientific Methods, Sept. i, 1904), was one of James's most original and significant philosophical contributions. It had been approximated by others, and anticipated by Ernst Mach, in his Beitrdge zur Analyse der Empfindungen (1886); but it remained for James to give it effect, and to deal a decisive blow at the Cartesian dualism which had infect- ed European philosophy for two centuries. These active and fruitful years culminated in the famous Pragmatism, published in 1907, and consisting of public lectures given in that year at Coltnnbia University, and in the preceding before, the Lowell Institute in Boston. In James 1898 James had given a lecture at Berkeley, Cal., entitled "Philosophical Conceptions and Prac- tical Results," the central idea of which he at- tributed to his old friend and fellow student Charles S. Peirce [g.v.]. This writer had also (Popular Science Monthly, Jan. 1878) used the name "pragmatism/* and despite Peirce's just protest that he meant something different by it, and the various misunderstandings to which it gave rise, this became the label by which James's teaching was thereafter known. Pragmatism was not a new departure, even for James him- self. It can be found in the concluding chapter of the Principles of Psychology, and in every book of James published after that time. It is the doctrine that the meaning of an idea consists in the particular consequences to which it leads. Particular consequences may be perceptual, practical, or emotional. If an, idea has no such consequences, it means nothing. If the conse- quences of two ideas are the same then there is really only one idea. Stress the perceptual conse- quences and one finds James's empiricist maxim, that a thing is what it is experienced as; stress the practical and emotional consequences, and one finds his voluntaristic doctrine that subjec- tive motives play, and deserve to play, an im- portant part in human beliefs. These more gen- eral doctrines now received, however, a new and striking application to the problem of "truth." This term, said James, should properly be applied, not to reality, but to our beliefs about it. There are then two important things to note: first, a particular truth must be "about" some- thing in particular; second, it must "work," that is, satisfy the purpose or interest for which it was adopted. Now in what does this relation "about" consist? James answered that an idea is about a certain object,—that object "of" which it is true, if it is true at all—only, when directly or indirectly, it "leads" to that object. Even to be false an idea must have a specific reference of this sort,—a reference that can be construed, he argued, only in terms of future behavior. Then if the belief is to have not only objective refer- ence, but also truth, the dealings to which it leads must be prosperous, whether in terms of fulfilled expectation, control, or emotional tone. The publication of Pragmatism at once gave rise to active controversy. James himself was anxious to make converts, and was greatly cheered by the agreement of G. Papini in Italy, as well as F. C. S. Schiller in England and John Dewey in America. There was, however, a storm of criticism, to which James replied in innumerable letters as well as in the articles afterwards collected and published under the; 598
