explained world of perception. Thus, in the end, will and thought are two names for two kinds of appearance. Neither, as such, can belong to the final Reality, and, in the end, both their unity and their diversity remains inexplicable. They may be offered as partial and as relative, but not as ultimate explanations.
But if their unity is thus unknown, should we call it their unity? Have they any right to arrogate to themselves the whole field of appearance? If we are to postulate thought and will where they are not observed, we should at least have an inducement. And, if after all they fail to explain our world, the inducement seems gone. Why should we strain ourselves to bring all phenomena under two heads, if, when we have forced them there, these heads, with the phenomena, remain unexplained? It would be surely better to admit that appearances are of more kinds, and have more aspects, than only two, and to allow that their unity is a mode of experience not directly accessible. And this result is confirmed when we recall some preceding difficulties. Pleasure and pain, feeling, and the aesthetic consciousness would hardly fall under any mere unity of intelligence and will; and again the relation of sensible qualities to their arrangements, the connection of matter with form, remained entirely inexplicable. In short, even if the unity of thought and will were by itself self-evident, yet the various aspects of the world can hardly be reduced to it. And, on the other side, even if this reduction were accomplished, the identity of will and thought, and their diversity, are still not understood. If finitude and process in time is reduced to their divergence, how is it they come to diverge? The reduction cannot be final, so long as the answer to such a question falls somewhere outside it.
The world cannot be explained as the appearance
