and mechanics. Thus the system of the Englishman Hobbes was science swelled to world-proportions, simple, compact, conclusive, and all-comprehensive. Philosophy proposed to do the work of science, but in its own grand manner. The last twenty years of Hobbes's life, spent in repeated discomfiture at the hands of Seth Ward, Wallis, Boyle, and other scientific experts of the new Royal Society, certified conclusively to the failure of this enterprise, and the experimental specialist thereupon took exclusive possession of the field of natural law. But the idealist, on the other hand, reconstructed nature to meet the demands of philosophical knowledge and religious faith. There issued, together with little mutual understanding and less sympathy, on the one hand positivism, or exclusive experimentalism, and on the other hand a rabid and unsympathetic transcendentalism. Hume, who consigned to the flames all thought save "abstract reasoning concerning quantity or number," and "experimental reasoning concerning matter of fact and existence"; Comte, who assigned metaphysics to an immature stage in the development of human intelligence; and Tyndall, who reduced the religious consciousness to an emotional experience of mystery, are typical of the one attitude. The other is well exhibited in Schelling's reference to "the blind and thoughtless mode of investigating nature which has become generally established since the corruption of philosophy by Bacon, and of physics by Boyle." Dogmatic experimentalism and dogmatic idealism signify more or less consistently the abstract isolation of the scientific and philosophical motives. There is already a touch of quaintness in both of these attitudes. We of the present are in the habit of acknowledging the autonomy of science, and the unimpeachable validity of the results of experimental research in so far as they are sanctioned by the consensus of experts. But at the same time we recognize the definiteness of the task of science, and the validity of such reservations as may be made from a higher critical point of view. Science is to be transcended in so far as it is understood as a whole. Philosophy is critically empirical; empirical, because it regards all bona fide de scriptions of experience as knowledge; critical, because attentive to the conditions of both general and special knowledge. And in terms of a critical empiricism so defined, it is one of the problems of philosophy to define and appraise the generating problem of science, and so to determine the value assignable to natural laws in the whole system of knowledge. Philosophy § 40. If this be the true function of philosophy with reference to science, several current notions The Spheres of of the relations of the spheres of these and Science. disciplines may be disproved. In the first place, philosophy will not be all the sciences regarded as one science. Science tends to unify without any higher criticism. The various sciences already regard the one nature as their common object, and the one system of interdependent laws as their common achievement. The philosopher who tries to be all science at once fails ignominiously because he tries to replace the work of a specialist with the work of a dilettante; and if philosophy be identical with that body of truth accumulated and organized by the coöperative activity of scientific men, then philosophy is a name and there is no occasion for the existence of the philosopher as such. Secondly, philosophy will not be the assembling of the sciences; for such would be a merely clerical work, and the philosopher would much better be regarded as non-existent than as a book-keeper. Nor, thirdly, is philosophy an auxiliary discipline that may be called upon in emergencies for the solution of some baffling prob lem of science. A problem defined by science must be solved in the scientific manner. Science will accept no aid from the gods when engaged in her own campaign, but will fight it out according to her own principles of warfare. And as long as science moves in her own plane, she can acknowledge no permanent barriers. There is then no need of any superscientific research that shall replace, or piece together, or extend the work of science. But the savant is not on this account in possession of the entire field of knowledge. It is true that he is not infrequently moved to such a conviction when he takes us about to view his estates. Together we ascend up into heaven, or make our beds in sheol, or take the wings of the morning and dwell in the uttermost parts of the sea-and look in vain for anything that is not work done, or work projected, by natural science. Persuade him, however, to define his estates, and he has circumscribed them. In his definition he must employ conceptions more fundamental than the working conceptions that he employs within his field of study. Indeed, in viewing his task as definite and specific he has undertaken the solution of the problem of philosophy. The logical self-consciousness has been awakened, and there is no honorable way of putting it to sleep again. This is precisely what takes place in any account of the generating problem of science. To define science is to define at least one realm that is other than science, the realm of active intellectual endeavor with its own proper categories. One cannot reflect upon science and assign it an end, and a method proper to that end, without bringing into the field of knowledge a broader field of experience than the field proper to science, broader at any rate by the presence in it of the scientific activity itself. Here, then, is the field proper to philosophy. The scientist qua scientist is intent upon his own determinate enterprise. The philosopher comes into being as one who is interested in observing what it is that the scientist is so intently doing. In taking this interest he has accepted as a field for investigation that which he would designate as the totality of interests or the inclusive experience. He can carry out his intention of defining the scientific attitude only by standing outside it, and determining it by means of nothing less than an exhaustive searching out of all attitudes. Philosophy is, to be sure, itself a definite activity and an attitude, but an attitude required by definition to be conscious of itself, and, if you please, con |
