This instrument of research I find to be the use, by the human person, of all the various energies of personality concentrated into one point; and the resultant spectacle of things or reality of things, which this concentrated vision makes clear, I call the original revelation of the complex vision of man. Having analyzed in the earlier portions of the book the peculiar nature of our organ of research and the peculiar difficulties-- amounting to a very elaborate work of art--which have to be overcome before this _concentration_ takes place, I proceed in the later portions of the book to make as clear as I can what kind of reality it is that we actually do succeed in grasping, when this concentrating process has been achieved. I indicate incidentally that this desirable concentration of the energies of personality is so difficult a thing that we are compelled to resort to our memory of what we experienced in rare and fortunate moments in order to establish its results. I suggest that it is not to our average moments of insight that we have to appeal, but to our exceptional moments of insight; since it is only at rare moments in our lives that we are able to enter into what I call the _eternal vision_. To what, then, does this conclusion amount, and what is this resultant reality, in as far as we are able to gather it up and articulate its nature from the vague records of our memory? I have endeavoured to show that it amounts to the following series of results. What we are, in the first place, assured of is the existence within our own individual body of a real actual living thing composed of a mysterious substance wherein what we call mind and what we call matter are fused and intermingled. This is our real and self-conscious soul, the thing in us which says, "I am I," of which the physical body is only one expression, and of which all the bodily senses are only one gateway of receptivity. The soul within us becomes aware of its own body simultaneously with its becoming aware of all the other bodies which fill the visible universe. It is then by an act of faith or imagination that the soul within us takes for granted and assumes that there must be a soul resembling our own soul within each one of those alien bodies, of which, simultaneously with its own, it becomes aware. And since the living basis of our personality is this real soul within us, it follows that all those energies of personality, whose concentration is the supreme work of art, are the energies of this real soul. If, therefore, we assume that all the diverse physical bodies which fill the universe possess, each of them, an inner soul resembling our own soul, we are led to the conclusion that just as our own soul half-creates and half-discovers the general spectacle of things which it names "the universe," so all the alien souls in the world half-create and half-discover what they feel as _their_ universe.
