There hover before me phenomena in space, to which I transfer the idea of my own being. I represent them to myself as beings of my own kind. Consistent speculation has taught me or will teach me that these supposed rational beings, without me, are only products of my own conception; that I am necessitated, once for all, by laws of thought which can be shown to exist, to represent the idea of myself out of myself, and that, according to the same laws, this idea can be transferred only to certain definite perceptions. But the voice of my conscience cries to me: "Whatever these beings may be in and for themselves, thou shalt treat them as subsisting for themselves, as free, self-existing beings, entirely independent of thyself. Take it for granted that they are capable of proposing to themselves aims independently of thee, by their own power. Never disturb the execution of these, their designs, but further them rather, with all thy might. Respect their liberty. Embrace with love their objects as thine own." So must I act. And to such action shall, will, and must all my thinking be directed, if I have but formed the purpose to obey the voice of my conscience. Accordingly, I shall ever consider those beings as beings subsisting for themselves, and forming and accomplishing aims independently of me. From this viewpoint, I cannot consider them in any other light; and the above-mentioned speculation will vanish like an empty dream before my eyes. "I _think_ of them as beings of my own species," said I just now; but strictly, it is not a thought by which they are first represented to me as such. It is the voice of conscience, the command: "Here restrain thy liberty, here suppose and respect foreign aims." This it is which is first translated into the thought: "Here is surely and truly, subsisting of itself, a being like me." To consider them otherwise, I must first deny the voice of my conscience in life and forget it in speculation.
