In other accounts the Philosopher's Stone, or at least the _materia prima_ of which it is compounded, is spoken of as a despised substance, reckoned to be of no value. Thus, according to one curious alchemistic work, "This matter, so precious by the excellent Gifts, wherewith Nature has enriched it, is truly mean, with regard to the Substances from whence it derives its Original. Their price is not above the Ability of the Poor. Ten Pence is more than sufficient to purchase the Matter of the Stone.... The matter therefore is mean, considering the Foundation of the Art because it costs very little; it is no less mean, if one considers exteriourly that which gives it Perfection, since in that regard it costs nothing at all, in as much as _all the World has it in its Power_... so that... it is a constant Truth, that the Stone is a Thing mean in one Sense, but that in another it is most precious, and that there are none but Fools that despise it, by a just Judgment of God."(1) And JACOB BOEHME (1575--1624) writes: "The _philosopher's stone_ is a very dark, disesteemed stone, of a grey colour, but therein lieth the highest tincture."(2) In these passages there is probably some reference to the ubiquity of the Spirit of the World, already referred to in a former quotation. But this fact is not, in itself, sufficient to account for them. I suggest that their origin is to be found in the religious doctrine that God's Grace, the Spirit of CHRIST that is the means of the transmutation of man's soul into spiritual gold, is free to all; that it is, at once, the meanest and the most precious thing in the whole Universe. Indeed, I think it quite probable that the alchemists who penned the above-quoted passages had in mind the words of ISAIAH, "He was despised and we esteemed him not." And if further evidence is required that the alchemists believed in a correspondence between CHRIST--"the Stone which the builders rejected"--and the Philosopher's Stone, reference may be made to the alchemical work called _The Sophic Hydrolith: or Water Stone of the Wise_, a tract included in _The Hermetic Museum_, in which this supposed correspondence is explicitly asserted and dealt with in some detail.
