As a protagonist of occult philosophy, Paracelsus has had a more enduring reputation than as a physician. In estimating his position there is the great difficulty referred to by Sudhoff in determining which of the extant treatises are genuine. In the two volumes issued in English by Waite in 1894, there is much that is difficult to read and to appreciate from our modern standpoint. In the book "Concerning Long Life" he confesses that his method and practice will not be intelligible to common persons and that he writes only for those whose intelligence is above the average. To those fond of transcendental studies they appeal and are perhaps intelligible. Everywhere one comes across shrewd remarks which prove that Paracelsus had a keen belief in the all-controlling powers of nature and of man's capacity to make those powers operate for his own good: "the wise man rules Nature, not Nature the wise man." "The difference between the Saint and the Magus is that the one operates by means of God, and the other by means of Nature." He had great faith in nature and the light of nature, holding that man obtains from nature according as he believes. His theory of the three principles appears to have controlled his conception of everything relating to man, spiritually, mentally and bodily; and his threefold genera of disease corresponded in some mysterious way with the three primary substances, salt, sulphur and mercury. How far he was a believer in astrology, charms and divination it is not easy to say. From many of the writings in his collected works one would gather, as I have already quoted, that he was a strong believer. On the other hand, in the "Paramirum," he says: "Stars control nothing in us, suggest nothing, incline to nothing, own nothing; they are free from us and we are free from them" (Stoddart, p. 185). The Archaeus, not the stars, controls man's destiny. "Good fortune comes from ability, and ability comes from the spirit" (Archaeus). No one has held more firmly the dualistic conception of the healing art. There are two kinds of doctors; those who heal miraculously and those who heal through medicine. Only he who believes can work miracles. The physician has to accomplish that which God would have done miraculously, had there been faith enough in the sick man (Stoddart, p. 194). He had the Hippocratic conception of the "vis medicatrix naturae"--no one keener since the days of the Greeks. Man is his own doctor and finds proper healing herbs in his own garden: the physician is in ourselves, in our own nature are all things that we need: and speaking of wounds, with singular prescience he says that the treatment should be defensive so that no contingency from without could hinder Nature in her work (Stoddart, p. 213).
