Second, is the equally universal principle of subjective (negative) sensibility--the receptiveness of spirit in its forms called "the senses." Transmuted through these senses, ultimate objective spirit--to us "the unknown and unknowable"--furnishes the filling, or contents, of what consciousness and sub-consciousness make up, or unify, into objects. Third, is the vast fact of Spirit-background--Infinite Spirit "in itself"--which is revealed, and can only be revealed, _to the finite_, as transformed through fixed modes of finite receptivity. A man, therefore, is simply an individualization of the process by which the Absolute--That Which Is--expresses itself and lives. Whatever may be our environment under some changed state of our receptivity--say "the future life"--our environment of spirit objected through sense, in space and time, is the environment of _matter_; and the human body is a part of it. We are not only "in matter," therefore, but we sub-create the matter, through our God-given modes of sensuous receptivity, and can only escape from it through an entire change of those modes, called "senses." The door of escape is the door of death, and no human being has ever avoided it. _Can_ any human being avoid it? We say _no_: because to be out of matter is to be out of the kind of receptiveness--our five senses--through which matter itself exists. If there be exceptional persons of clairvoyant susceptibility, who can pass sufficiently out of our average material condition to realize aught beyond them, the _bodily_ state of these persons, too, must end, as we all end. Let us not mix conditions, like the metaphysical tyros of Christian Science; but while we are in the state of spirit known and experienced as mind _and_ matter, let us acknowledge the plain fact. As a corollary of this fact, if we are out of health, let us look to remedies good for _both mind and matter_--the body and the soul. Such will probably be the ultimate equipoise between "mental medicine" and material curatives. This, at any rate, is the best conclusion for "the new thought" that the scribe at hand can reach. He may be wrong; for he is totally "uninspired," and has nothing to follow but his nose and his "mortal mind." But, the conclusion once reached, he stood on it as an _a-priori_ breathing-spot. And then it occurred to him that, peradventure, some radical, independent son of Galen might be conducting the business of therapeutics on a psycho-corporeal, double platform. If so, Boston would be the place to look for him, and the search was begun. In due time it was successful. The result may at least prove suggestive and entertaining. Let our new friend be called Prof. P.; for he has been an instructor in his kind of work, and he bears the title of "doctor" only by the courtesy of his patients, as Dr. Quimby did.
