We may see how the matter stands by inquiring what would be the effect upon philosophy if self-consciousness were not an experienced fact, i.e., if it were not one actual stage in that realization of the universe by an individual which is defined as constituting the sphere of psychology. The result would be again, precisely, that no such thing as philosophy, under any theory of its nature whatever, is possible. Philosophy, it cannot be too often repeated, consists simply in viewing things sub specie aeternitatis or in ordine ad universum. If man, as matter of fact, does not realize the nature of the eternal and the universal within himself, as the essence of his own being; if he does not at one stage of his experience consciously, and in all stages implicitly, lay hold of this universal and eternal, then it is a mere matter of words to say that he can give no account of things as they universally and eternally are. To deny, therefore, that self-consciousness is a matter of psychological experience is to deny the possibility of any philosophy.
What the denial comes to we have had historically demonstrated in Kant. He admits perception and conception as matters of experience, but he draws the line at self-consciousness. It is worth noticing that his reason for denying it is not psychological at all, but logical. It is not because self-consciousness is not a fact, but because it cannot be a fact according to his logical presuppositions. The results following the denial are worthy of notice as corresponding exactly to what we might be led to expect: first, with the denial of the fact of self-consciousness comes the impossibility of solving the problem of philosophy, expressed in the setting up of an unknown thing-in-itself as the ultimate ground and condition of experience; and, secondly, comes the failure to bring perception and conception into any organic connection with experience, that is, the failure to really comprehend and explain them, manifested in the limitation of both perception, through the forms of space and time, and thinking, through the categories, to phenomena which are in no demonstrable connection with reality. The failure to recognize self-consciousness as a stage of psychological experience leads not only to a failure to reach the alternate synthesis of experience, but renders it impossible to explain the simpler forms of psychological experience. This failure of Kant teaches us another lesson also, in that, as already stated, it was due to abandoning his real method, which was psychological, consisting in the self-knowledge of reason as an organic system by reason itself, and setting up a logical standard (in this latter case the principles of non-contradiction and identity), by which to determine the totality of experience. The work of Hegel consisted essentially in showing that Kant's logical standard was erroneous, and that, as matter of logic, the only true criterion or standard was the organic notion, or Begriff, which is a systematic totality, and accordingly able to explain both itself and also the simpler processes and principles. That Hegel accomplished this work successfully and thoroughly there can be to the writer no doubt; but it seems equally clear that the work of Kant is in need of another complement, following more closely his own conception of method and of philosophy, which shall consist in showing self-consciousness as a fact of experience, as well as perception through organic forms and thinking through organic principles. And it seems further that, only when this has been done, will, for the first time, the presuppositions latent in the work of Hegel, which give it its convincing force and validity, be brought out.
Again, it seems worthy of note that the late Professor Green (of whom the writer would not speak without expressing his deep, almost reverential gratitude), when following out Kant's work from its logical side, hardly escaped Kant's negative results. (By Kant's logical method we mean the inquiry into the necessary conditions of experience; by his psychological method the inquiry into the actual nature of experience.) After his complete demonstration of consciousness as the final condition, synthesis and unity of all that is or is knowable, he finds himself obliged to state (Prolegg. to Ethics, p. 54): "As to what that consciousness in itself or in its completeness is, we can only make negative statements. That there is such a consciousness is implied in the existence of the world; but what it is we can only know through its so far acting in us as to enable us, however partially and interruptedly, to have knowledge of a world or an intelligent experience." Had he begun from the latter statement, and shown as matter of fact that this universal consciousness had realized itself, though only partially and interruptedly, in us, he certainly would have been able to make very positive statements regarding it, and would also have furnished a basis in fact for his logical method, which now seems to hang upon nothing but a unity of which all that can be said is that it is a unity, and that it is not anything in particular. When one reflects that it is not only upon the existence of this unity, but upon its working in and through us, that all philosophy and philosophizing depend, one cannot conceal the apprehension that too great a load of philosophy has been hung upon too feeble a peg.
So, too, after his victorious demonstration that upon the existence of this spiritual unity depends the possibility of all moral experience, he finds himself obliged to state (p. 180), with that candor so characteristic of all his thinking: ''Of a life of completed development, of activity with the end attained, we can only speak or think in negatives, and thus only can we speak or think of that state of being in which, according to our theory, the ultimate moral good must consist." Once more, had he started from the fact that as matter of actual realization this absolute good has been reproduced in our lives and the end attained (for surely the good is a matter of quality and not of quantity, and the end a power, not a sum), he would not have found himself in this difficulty. But with a purely logical method, one can end only with the must be or the ought: the is vanishes, because it has been abstracted from. The psychological method starts from the is, and thereby also gives the basis and the ideal for the ought and must be.
But it is time that we returned to our thesis, which, in brief, was that no distinction which maintains that psychology is the science of man as "part of this partial world'' can be maintained. The following reasons for this denial have been given: it was pointed out that the relative validity which this distinction in man's nature undoubtedly possesses is itself the product and manifestation of psychological experience; that man as man, or as the conscious experience whose science is psychology, is self-conscious, and that therefore self-consciousness as the unity of subject and object, not as "purely objective," as the totality, not as a "part," must be included in the science of psychology; and that furthermore this treatment of self-consciousness is necessary for the explanation and comprehension of any partial fact of conscious experience. And finally, it was pointed out that the denial of self-consciousness as constituting matter of experience, and hence of psychology, was the denial of the possibility
