This suggests, finally, that the next move in philosophy is precisely to transfer attention from the details of the position assumed, and the arguments used in these two schools, to the practical motives that have unconsciously controlled the discussion. The positions have been sufficiently elaborated. Within the past one hundred years, within especially the last generation, each has succeeded in fully stating its case. The result, if we remain at this point, is practically a deadlock. Each can make out its case against the other. To stop at such a point is a patent absurdity. If we are to get out of the cul-de-sac it must be by bringing into consciousness the tacit reference to action that all the time has been the controlling factor. In a word, another great rhythmic movement is seen to be approaching its end. The demand for science and philosophy was the demand for truth and a sure standard of truth which the new-born individual might employ in his efforts to build up a new world to afford free scope to the powers stirring within him. The urgency and acuteness of this demand caused, for the time being, the transfer of attention from the nature of practice to that of knowledge. The highly theoretical and abstract character of modern epistemology, combined with the fact that this highly abstract and theoretic problem has continuously engaged the attention of thought for more than three centuries, is, to my mind, proof positive that the question of knowledge was for the time being the point in which the question of practice centered, and through which it must find outlet and solution. We return, then, to our opening problem: the meaning of the question of the possibility of knowledge raised by Kant a century ago, and of his assertion that sensation without thought is blind, thought without sensation empty. Once more I recall to the student of philosophy how this assertion of Kant has haunted and determined the course of philosophy in the intervening years--how his solution at once seems inevitable and unsatisfactory. It is inevitable in that no one can fairly deny that both sense and reason are implicated in every fruitful and significant statement of the world; unconvincing because we are after all left with these two opposed things still at war with each other, plus the miracle of their final combination. When I say that the only way out is to place the whole modern industry of epistemology in relation to the conditions that gave it birth and the function it has to fulfil, I mean that the unsatisfactory character of the entire neo-Kantian movement lies in its assumption that knowledge gives birth to itself and is capable of affording its own justification. The solution that is always sought and never found so long as we deal with knowledge as a self-sufficing purveyor of reality, reveals itself when we conceive of knowledge as a statement of action, that statement being necessary, moreover, to the successful ongoing of action.
