Such also was the doctrine of Tenzel Wirdig. It may even be found expounded in his works, with far more clearness, logic, and vigor, than in those of other mystical authors who have treated of the same subject. In his famous treatise, _The New Spiritual Medicine_, he demonstrates, on the ground of the later-accepted fact of universal attraction and repulsion—now called “gravitation” that the whole nature is _ensouled_. Wirdig calls this magnetic sympathy “the accordance of spirits.” Everything is drawn to its like, and converges with natures congenial to itself. Out of this sympathy and antipathy arises a constant movement in the whole world, and in all its parts, and uninterrupted communion between heaven and earth, which produces universal harmony. Everything lives and perishes through magnetism; one thing affects another one, even at great distances, and its “congenitals” may be influenced to health and disease by the power of this sympathy, at any time, and notwithstanding the intervening space.[346] “Hufeland,” says Ennemoser, “gives the account of a nose which had been cut from the back of a porter, but which, when the porter died, died too and fell off from its artificial position. A piece of skin,” adds Hufeland, “taken from a living head, had its hair turn gray at the same time as that on the head from which it was taken.”[347] Kepler, the forerunner of Newton in many great truths, even in that of the universal “gravitation” which he very justly attributed to magnetic attraction, notwithstanding that he terms astrology “the insane daughter of a most wise mother” Astronomy, shares the kabalistic belief {208} that the spirits of the stars are so many “intelligences.” _He firmly believes that each planet is the seat of an intelligent principle, and that they are all inhabited by spiritual beings, who exercise influences over other beings inhabiting more gross and material spheres than their own and especially_ our earth.[348] As Kepler’s _spiritual_ starry influences were superseded by the vortices of the more materialistic Descartes, whose atheistical tendencies did not prevent him from believing that he had found out a diet that would prolong his life five hundred years and more, so the vortices of the latter and his astronomical doctrines may some day give place to the _intelligent_ magnetic streams which are directed by the _Anima Mundi_.
