disease, him that shall take upon him to cure it, [2844]Paracelsus will have to be a magician, a chemist, a philosopher, an astrologer; Thurnesserus, Severinus the Dane, and some other of his followers, require as much:  “many of them cannot be cured but by magic.” [2845]Paracelsus is so stiff for those chemical medicines, that in his cures he will admit almost of no other physic, deriding in the mean time Hippocrates, Galen, and all their followers:  but magic, and all such remedies I have already censured, and shall speak of chemistry [2846]elsewhere.  Astrology is required by many famous physicians, by Ficinus, Crato, Fernelius; [2847]doubted of, and exploded by others:  I will not take upon me to decide the controversy myself, Johannes Hossurtus, Thomas Boderius, and Maginus in the preface to his mathematical physic, shall determine for me.  Many physicians explode astrology in physic (saith he), there is no use of it, unam artem ac quasi temerarium insectantur, ac gloriam sibi ab ejus imperitia, aucupari:  but I will reprove physicians by physicians, that defend and profess it, Hippocrates, Galen, Avicen. &c., that count them butchers without it, homicidas medicos Astrologiae ignaros, &c.  Paracelsus goes farther, and will have his physician [2848]predestinated to this man’s cure, this malady; and time of cure, the scheme of each geniture inspected, gathering of herbs, of administering astrologically observed; in which Thurnesserus and some iatromathematical professors, are too superstitious in my judgment. [2849]"Hellebore will help, but not alway, not given by every physician,” &c. but these men are too peremptory and self-conceited as I think.  But what do I do, interposing in that which is beyond my reach?  A blind man cannot judge of colours, nor I peradventure of these things.  Only thus much I would require, honesty in every physician, that he be not over-careless or covetous, harpy-like to make a prey of his patient; Carnificis namque est (as [2850]Wecker notes) inter ipsos cruciatus ingens precium exposcere, as a hungry chirurgeon often produces and wire-draws his cure, so long as there is any hope of pay, Non missura cutem, nisi plena cruoris hirudo. [2851]Many of them, to get a fee, will give physic to every one that comes, when there is no cause, and they do so irritare silentem morbum, as [2852]Heurnius complains, stir up a silent disease, as it often falleth out, which by good counsel, good advice alone, might have been happily composed, or by rectification of those six non-natural things otherwise cured.  This is Naturae bellum inferre, to oppugn nature, and to make a strong body weak.  Arnoldus in his 8 and 11 Aphorisms gives cautions against, and expressly forbiddeth it. [2853]"A wise physician will not give physic, but upon necessity, and first try medicinal diet, before he proceed to medicinal cure.” [2854]In another place he laughs those men to scorn, that think longis syrupis expugnare daemones et animi phantasmata,
