The powers in whose manifestation my personality consists,—the formative—the self-moving—the thinking powers,—are not these same powers as they exist in Nature at large, but only a certain definite portion of them; and that they are but such a portion, is because there are so many other existences beyond me. From the former, I can infer the latter; from the limitation, the power which limits. Because I myself am not this or that, which yet belongs to the connected system of existence, it must exist beyond me;—thus reasons the thinking principle within me. Of my own limitation, I am immediately conscious, because it is a part of myself, and only by reason of it do I possess an actual existence; my consciousness of the source of this limitation,—of that which I myself am not,—is produced by the former, and arises out of it.
Away, then, with those pretended influences and operations of outward things upon me, by means of which they are supposed to pour in upon me a know ledge which is not in themselves and cannot flow forth from them. The ground upon which I assume the existence of something beyond myself, does not he out of myself, but within me, in the limitation of my own personality. By means of this limitation, the thinking principle of Mature within me proceeds out of itself, and is able to survey itself as a whole, although, in each individual, from a different point of view.
In the same way there arises within me the idea of other thinking beings like myself. I, or the thinking power of Nature within me, possess some thoughts which seem to have developed themselves within myself as a particular form of Nature; and others, which seem not to have so developed themselves. And so it is in reality. The former are my own, peculiar, individual contribution to the general circle of thought in Nature; the latter are deduced from them, as what must surely have a place in that circle; but, being only inferences so far as I am concerned, must find that place, not in me, but in other thinking beings:—hence I conclude that there are other thinking beings besides myself. In short, Nature, in me, becomes conscious of herself as a whole, but only by beginning with my own individual consciousness, and proceeding from thence to the consciousness of universal being by inference founded on the principle of causality;—that is, she is conscious of the conditions under which alone such a form, such a motion, such a thought as that in which my personality consists, is possible. The principle of causality is the point of transition, from the particular within my self, to the universal which lies beyond myself; and the distinguishing characteristic of these two kinds of knowledge is this, that the one is immediate perception, while the other is inference.
In each individual, Nature beholds herself from a particular point of view. I call myself—I, and thee—thou;thou callest thyself—I, and me—thou;I lie beyond thee, as thou beyond me. Of what is without me, I comprehend first those things which touch me most nearly; thou, those which touch thee most nearly;—from these points we each proceed onwards to the next proximate; but we describe very different paths, which may here and there intersect each other, but never run parallel. There is an infinite variety of possible individuals, and hence also an infinite variety of possible starting points of consciousness. This consciousness of all individuals taken together, constitutes the complete consciousness of the universe; and there is no other, for only in the individual is there perfect precision and reality.
The testimony of consciousness in every individual is altogether sure and trustworthy, if it be indeed the consciousness here described; for this consciousness developes itself out of the whole prescribed course of Nature. Nature, however, cannot contradict herself; wherever there is a conception, there must be a corresponding existence, for conceptions are only produced simultaneously with the production of the corresponding realities. To each individual his own particular consciousness is wholly determined, for it proceeds from his own nature:—no one can have other conceptions, or a greater or less degree of vitality in these conceptions, than he actually has. The substance of his conceptions is determined by the position which he assumes in the universe; their clearness and vitality, by the higher or lower degree of efficiency manifested by the power of humanity in his person.
