What did Franz Mesmer believe about the moon?
Much like Yoda, Austrian physician Franz Mesmer (1734-1815) believed that an invisible force pervaded everything in existence , and that disruptions in this force caused pain and suffering. But Mesmer's ideas would have been of little use to Luke Skywalker. His basic theory was that the gravity of the moon affected the body's fluids in much the same way it caused ocean tides, and that some diseases accordingly waxed and waned with the phases of the moon. The dilemma, then, was to uncover what could be done about gravity's pernicious effects. Mesmer's solution: use magnets. After all, gravity and magnetism were both about objects being attracted to each other. Thus, placing magnets on certain areas of a patient's body might be able to counteract the disruptive influence of the moon's gravity and restore the normal flow of bodily fluids.
