One of the names given by the alchemists to the conscience, on this theory, is that of a middle substance which partakes of an azurine sulphur--that is, of a celestial spirit--the Spirit of God. “The still small voice is in alchemy, as in Scripture, compared to a _fire_, which prepares the way for what many of the writers speak of as a _Light_.” Hitchcock elsewhere more emphatically asserts that there is but one subject within the wide circle of human interests that can furnish an interpretation of the citations which he gives, and it is that which is known under the theological name of spiritual Regeneration. This gift of God the alchemists investigated as a work of Nature within Nature. “The repentance which in religion is said to begin conversion, is the ‘philosophical contrition’ of Hermetic allegory. It is the first step of man towards the discovery of his whole being. They also called it the black state of the matter, in which was carried on the work of dissolution, calcination, separation, &c., after which results purification, the white state, which contains the red, as the black contained the white.” The evolution of the glorious and radiant red state resulted in the fixation or perfection of the matter, and then the soul was supposed to have entered into its true rest in God. As this interpretation is concerned chiefly with the conscience, I have called it the moral theory of alchemy; but Hitchcock, as a man of spiritual insight, could not fail to perceive that his explanatory method treated of the way only, and the formless light of an “End,” which he could not or would not treat of, is, upon his own admission, continually glimmering before him. For the rest, when the alchemists speak of a long life as one of the endowments of the Stone, he considers that they mean immortality; when they attribute to it the miraculous properties of a universal medicine, it is their intention to deny any positive qualities to evil, and, by inference, any perpetuity. When they assert that the possession of the Stone is the annihilation of covetousness and of every illicit desire, they mean that all evil affections disappear before the light of the unveiled Truth. By the transmutation of metals they signified the conversion of man from a lower to a higher order of existence, from life natural to life spiritual, albeit these expressions are inadequate to convey the real meaning of the adepts. The powers of an ever active nature must be understood by such expressions as “fires,” “menstruums,” &c., which work in unison because they work in Nature, the alchemists unanimously denying the existence of any disorder in the creation of God.
