THE SIGNIFICANCE OF THE PROBLEM OF KNOWLEDGE[63]

It is now something over a century since Kant called upon philosophers to cease their discussion regarding the nature of the world and the principles of existence until they had arrived at some conclusion regarding the nature of the knowing process. But students of philosophy know that Kant formulated the question “how knowledge is possible” rather than created it. As matter of fact, reflective thought for two centuries before Kant had been principally interested in just this problem, although it had not generalized its own interest. Kant brought to consciousness the controlling motive. The discussion, both in Kant himself and in his successors, often seems scholastic, lost in useless subtlety, scholastic argument, and technical distinctions. Within the last decade in particular there have been signs of a growing weariness as to epistemology, and a tendency to turn away to more fertile fields. The interest shows signs of exhaustion.

Students of philosophy will recognize what I mean when I say that this growing conviction of futility and consequent distaste are associated with the outcome of the famous dictum of Kant, that perception without conception is blind, while conception without perception is empty. The whole course of reflection since Kant’s time has tended to justify this remark. The sensationalist and the rationalist have worked themselves out. Pretty much all students are convinced that we can reduce knowledge neither to a set of associated sensations, nor yet to a purely rational system of relations of thought. Knowledge is judgment, and judgment requires both a material of sense perception and an ordering, regulating principle, reason; so much seems certain, but we do not get any further. Sensation and thought themselves seem to stand out more rigidly opposed to each other in their own natures than ever. Why both are necessary, and how two such opposed factors coöperate in bringing about the unified result of science, becomes more and more of a mystery. It is the continual running up against this situation which accounts for the flagging of interest and the desire to direct energy where it will have more outcome.

This situation creates a condition favorable to taking stock of the question as it stands; to inquiring what this interest, prolonged for over three centuries, in the possibility and nature of knowledge, stands for; what the conviction as to the necessity of the union of sensation and thought, together with the inability to reach conclusions regarding the nature of the union, signifies.

I propose then to raise this evening precisely this question: What is the meaning of the problem of knowledge? What is its meaning, not simply for reflective philosophy or in terms of epistemology itself, but what is its meaning in the historical movement of humanity and as a part of a larger and more comprehensive experience? My thesis is perhaps sufficiently indicated in the mere taking of this point of view. It implies that the abstractness of the discussion of knowledge, its remoteness from everyday experience, is one of form, rather than of substance. It implies that the problem of knowledge is not a problem that has its origin, its value, or its destiny within itself. The problem is one which social life, the organized practice of mankind, has had to face. The seemingly technical and abstruse discussion of the philosophers results from the formulation and statement of the question.

I suggest that the problem of the possibility of knowledge is but an aspect of the question of the relation of knowing to acting, of theory to practice. The distinctions which the philosophers raise, the oppositions which they erect, the weary treadmill which they pursue between sensation and thought, subject and object, mind and matter, are not invented ad hoc, but are simply the concise reports and condensed formula of points of view and practical conflicts having their source in the very nature of modern life, conflicts which must be met and solved if modern life is to go on its way untroubled, with clear consciousness of what it is about. As the philosopher has received his problem from the world of action, so he must return his account there for auditing and liquidation.

More especially, I suggest that the tendency of all the points at issue to precipitate in the opposition of sensationalism and rationalism is due to the fact that sensation and reason stand for the two forces contending for mastery in social life: the radical and the conservative. The reason that the contest does not end, the reason for the necessity of the combination of the two in the resultant statement, is that both factors are necessary in action; one stands for stimulus, for initiative; the other for control, for direction.

I cannot hope, in the time at my command this evening, to justify these wide and sweeping assertions regarding either the origin, the work, or the final destiny of philosophic reflection. I simply hope, by reference to some of the chief periods of the development of philosophy, to illustrate to you something of what I mean.

At the outset we take a long scope in our survey and present to ourselves the epoch when philosophy was still consciously, and not simply by implication, human, when reflective thought had not developed its own technique of method, and was in no danger of being caught in its own machinery—the time of Socrates. What does the assertion of Socrates that an unexamined life is not one fit to be led by man; what does his injunction “Know thyself” mean? It means that the corporate motives and guarantees of conduct are breaking down. We have got away from the time when the individual could both regulate and justify his course of life by reference to the ideals incarnate in the habits of the community of which he is a member. The time of direct and therefore unconscious union with corporate life, finding therein stimuli, codes, and values, has departed. The development of industry and commerce, of war and politics, has brought face to face communities with different aims and diverse habits; the development of myth and animism into crude but genuine scientific observation and imagination has transformed the physical widening of the horizon, brought about by commerce and intercourse, into an intellectual and moral expansion. The old supports fail precisely at the time when they are most needed—before a widening and more complex scene of action. Where, then, shall the agent of action turn? The “Know thyself” of Socrates is the reply to the practical problem which confronted Athens in his day. Investigation into the true ends and worths of human life, sifting and testing of all competing ends, the discovery of a method which should validate the genuine and dismiss the spurious, had henceforth to do for man what consolidated and incorporate custom had hitherto presented as a free and precious gift.
