Noted metaphysical author and physician, Franz Hartmann gives us an intriguing look into the esoteric aspects of medicine and human health. He helps us to understand the meaning of "disease" as well as covers subjects such as "The Constitution of Man;" "The Four Pillars of Medicine;" "The Five Causes of Disease;" "The Five Classes of Physicians;" "The Medicine of the Future" and more. This is a photographic reproduction of the 1893 edition of this work.
