The entire problem of medieval philosophy is that of absorption, of assimilation. The result was the creation of the individual. Hence the problem of modern life is that of reconstruction, reform, reorganization. The entire content of experience needs to be passed through the alembic of individual agency and realization. The individual is to be the bearer of civilization; but this involves a remaking of the civilization that he bears. Thus we have the dual question: How can the individual become the organ of corporate action? How can he make over the truth authoritatively embodied in institutions of church and state into frank, healthy, and direct expressions of the simple act of free living? On the other hand, how can civilization preserve its own integral value and import when subordinated to the agency of the individual instead of exercising supreme sway over him? The question of knowledge, of the discovery and statement of truth, gives the answer to this question; and it alone gives the answer. Admitting that the practical problem of modern life is the maintenance of the moral values of civilization through the medium of the insight and decision of the individual, the problem is foredoomed to futile failure save as the individual in performing his task can work with a definite and controllable tool. This tool is science. But this very fact, constituting the dignity of science and measuring the importance of the philosophic theory of knowledge, conferring upon them the religious value once attaching to dogma and the disciplinary significance once belonging to political rules, also sets their limit. The servant is not above his master. When a theory of knowledge forgets that its value rests in solving the problem out of which it has arisen, viz., that of securing a method of action; when it forgets that it has to work out the conditions under which the individual may freely direct himself without loss to the historic values of civilization--when it forgets these things it begins to cumber the ground. It is a luxury, and hence a social nuisance and disturber. Of course, in the very nature of things, every means or instrument will for a while absorb attention so that it becomes the end. Indeed it is the end when it is an indispensable condition of onward movement. But when once the means have been worked out they must operate as such. When the nature and method of knowledge are fairly understood, then interest must transfer itself from the possibility of knowledge to the possibility of its application to life.
