Such a standpoint promises ample revenge for the long damnation and longer neglect to which the principle of belief has been subjected. The whole procedure of thinking as developed in those extensive and intensive inquiries that constitute the sciences, is but rendering into a systematic technique, into an art deliberately and delightfully pursued, the rougher and cruder means by which practical human beings have in all ages worked out the implications of their beliefs, tested them, and endeavored in the interests of economy, efficiency, and freedom, to render them coherent with one another. Belief, sheer, direct, unmitigated belief, reappears as the working hypothesis; action that at once develops and tests belief reappears in experimentation, deduction, demonstration; while the machinery of universals, axioms, _a priori_ truths, etc., becomes a systematization of the way in which men have always worked out, in anticipation of overt action, the implications of their beliefs, with a view to revising them, in the interests of obviating unfavorable, and securing welcome consequences. Observation, with its machinery of sensations, measurements, etc., is the resurrection of the way in which agents have always faced and tried to define the problems that face them; truth is the union of abstract postulated meanings and of concrete brute facts in a way that circumvents the latter by judging them from a new standpoint, while it tests concepts by using them as methods in the same active experience. It all comes to experience personally conducted and personally consummated. Let consciousness of these facts dawn a little more brightly over the horizon of epistemological prejudices, and it will be seen that nothing prevents admitting the genuineness both of thinking activities and of their characteristic results, except the notion that belief itself is not a genuine ingredient of existence--a notion which itself is not only a belief, but a belief which, unlike the convictions of the common man and the hypotheses of science, finds its proud proof in the fact that it does not demean itself so unworthily as to work.
