The mind is first, foremost, creative and supreme. It takes the initiative in all processes. He that assumes the existence of an external world does so on the authority of consciousness. If he says that consciousness compels us to assume the existence of such a world, that it is so constituted as to imply the realization of its conception, still we have simply the fact of consciousness; power to verify the relation between this inner fact and a corresponding physical representation, there is none. Analyze the facts of consciousness as much as we may, revise them, compare them, we are still within their circle and cannot pass beyond its limit. Is it urged that the existence of an external world is a _necessary_ postulate? The same reply avails, namely, that the idea of necessity is but one of our ideas, a conception of the mind, an inner notion or impression which legitimates itself alone. Does the objector further insist, in a tone of exasperation caused by what seems to him quibbling, that in this case consciousness plays us false, makes a promise to the ear which it breaks to the hope--lies, in short? The imperturbable philosopher sets aside the insinuation as an impertinence. The fact of consciousness, he maintains, stands and testifies for itself. It is not answerable for anything out of its sphere. In saying what it does it speaks the truth; the whole truth, so far as we can determine. Whether or no it is absolutely the whole truth, the truth as it lies in a mind otherwise constituted, is no concern of ours. The reasoning by which Fichte cut off the certainty of a material world outside of the mind, told with equal force against the objective existence of a spiritual world. The mental vision being bounded by the mental sphere, its objects being there and only there, with them we must be content. The soul has its domain, untrodden forests to explore, silent and trackless ways to follow, mystery to rest in, light to walk by, fountains and floods of living water, starry firmaments of thought, continents of reason, zones of law, and with this domain it must be satisfied. God is one of its ideas; immortality is another; that they are anything more than ideas, cannot be known.
