James and by other vestiges of intellectualism in both his doctrine and his style. Hodgson's later re- jection of pragmatism widened the philosophical gap between them, though without in the least chilling the warmth of their friendship. To Re- nouvier, James was attracted both because, like Hodgson, he proposed that philosophy should concern itself with the phenomena of conscious experience, and because, unlike Hodgson, he provided for the efficacy and freedom of the will. It had been characteristic of later British em- piricism, as exemplified by Hume and J. S. Mill, to recognize the operation of practical motives in determining belief. While experience is the only ground of what can strictly be regarded as knowledge, this does not wholly satisfy man's moral and emotional nature and must be supple- mented by faith, which is legitimate provided it be recognized as such. Hodgson accepted faith, in this sense, as affording access to an "unseen world" beyond matter. Renouvier found in Kant authority for a similar philosophy of faith, but gave it a wider extension and more radical inter- pretation. Even knowledge is not complete with- out belief, which as definitive acceptance or re- jection is an act of will; and is always, in the last analysis, governed by subjective motives. Experience provides the content of knowledge, logic excludes contradictory impossibilities, but will seals and delivers it. The first step, there- fore, in the cognitive as well as in the moral life, is'to affirm one's own freedom. It was to this inspiriting challenge that James had re- sponded in 1870. But Renouvier went further in his provision for freedom. Rejecting the notion of a completed infinite (or innumerable quan- tity), he concluded that natural processes really begin and end discontinuously. He was, in other words, a pluralist in his conception of nature; and nature so conceived was consistent with the novelty and creativity implied in that doctrine of free will which he had adopted on other grounds. It was this prospect of a philosophy that should be at once empirical, metaphysical, coherent, and auspicious which saved James from his doubts and convinced him that he had something to say to his day and generation. In the course of time he became more and more alienated by Renouvier's "scholastic manner and apparatus," and by what seemed to be his apos- tasy to the professions of his earlier years; nev- ertheless, the last systematic work which he composed (Some Problems of Philosophy) was dedicated to Renouvier's memory, and testified to the "decisive impression" which that philoso- phy had made upon him in the crucial period between 1870 and 1880. James ^ James's philosophy w'as thus a union of em- piricism and voluntarism. It differed from ear- lier empiricisms and voluntarisms in being more radical: he found experience to be a richer and more adequate source of knowledge, and he found the will to be its more fundamental and per- vasive condition. It was the radical voluntarism, which was first developed, in The Will to Be- lieve and Other Essays, published intermittently from 1879, and collected in a single volume in 1897. The radical empiricism had been antici- pated in the Principles, and it was formally an- nounced in the Preface of The Will to Believe. Of this volume it affords, however, the back- ground and frame rather than the subject-matter. It was elaborated and freshly emphasized some years later. Of the essays represented in The Will to Be- lieve the most significant for the understanding of James's philosophy as a whole is "The Senti- ment of Rationality," which was made up of two of his earliest philosophical publications, an article of the same name which appeared in Mind in July 1879, and an article entitled "Ra- tionality, Activity and Faith," which had also been written in 1879 but did not appear until 1882 (Princeton Review). These two articles, together with "Reflex Action and Theism" (Uni- tarian Review), which had appeared in Novem- ber 1881, and w'as also republished in The Will to Believe t were parts of a work that was never completed in systematic form, a work "on the motives which lead men to philosophize." The "Sentiment of Rationality" dealt with "the pure- ly theoretical or logical impulse,"—comprising the "passion for simplification" and the opposite passion for making distinctions. The remaining chapters of the work were to treat of "practical and emotional motives," and of the comparative "soundness of different philosophies," as judged by all of the philosophical motives, theoretical, practical, and emotional, taken together. This was announced as a purely psychological project. But the titular essay, "The Will to Believe," took the more advanced position that philosophies might legitimately be adopted from such motives. James afterwards regretted the title because it suggested a wilful credulity which was far from his intention, and said that his central idea would have been better expressed by a title such as "The Right to Believe." When, as in the case of philosophy and religion, men go beyond the evident facts, they not only will, but rightly may, allow their "passional nature" to decide. The only alternative is to avoid decision and adopt a timid and non-committal attitude; which is, however, equivalent to a negative belief having 595
