" For true Magick means "to employ one set of natural forces at a mechanical advantage as against another set"—I quote, as closely as memory serves, Thomas Henry Huxley, when he explains that when he lifts his water-jug—or his elbow—he does not "defy the Law of Gravitation." On the contrary, he uses that Law; its equations form part of the system by which he lifts the jug without spilling the water. "
