Not being masters of Alchemy, we are not capable of teaching the science of this pillar of medicine; neither could any information in regard to the way in which certain mysterious powers are used be of any service to those who, not having developed these powers, are not in possession of them. The following remarks are therefore rather intended to show what Alchemy is _not_, than to show what it is; for like every term symbolising a spiritual truth, which ever fell into the hands of the vulgar, so this term has been “besmirched with mud and prostituted openly in the market place,”[16] so as to be now almost beyond recognition. The ancient alchemists used a mysterious language when speaking about mysterious things, nor could any modern alchemist express in plain language things for which our language has no words and common minds no conception. Children often speak more wisely than they know, sages know what they speak, but the half learned speak without knowing. The child receiving gifts from its parents on Christmas eve believes that the Christ has sent these presents, but the grown-up and clever boy becomes sceptical and laughs at that story. In that opinion he may now continue all his life, or he may become still more clever and find that the Christ is divine love, from which the love of his parents originated, inducing them to bestow gifts, and that the story which he believed when a child, was true after all. In the same sense Alchemy is either a truth or a superstition; it merely depends on the definition we give to this term. Professor Justus von Liebig says: “Alchemy was never anything different from Chemistry,” and to this we agree in so far as both deal with substantial things, having certain affinities, and not with anything existing outside of nature; but while ordinary (physical) chemistry employs merely physical (mechanical) forces for the purpose of composing and decomposing material substances without causing anything new to grow, Alchemy employs the power of life and uses animated forces, establishing conditions under which something visible may grow from something invisible, in the same sense as a tree grows from a seed in the alchemical laboratory of nature. Chemistry and Alchemy are therefore two aspects of one and the same science, the one is the lower, the other the higher part. The chemist who decomposes salt into NA and CL, and recombines it into NACL, practises chemistry; the gardener establishing in his hot house the conditions under which the seed of a plant of a lower type is made to develop into a plant of a higher type, and the schoolmaster who makes an intelligent being out of a dunce, are practicing Alchemy, because they produce something more noble than the materials employed, out of the latent potencies contained therein.
