The world of magic is double, natural, and supernatural. Magic is impossible in a purely materialist world, a purely sceptical world, a world of pure reason. Magic depends on, it makes use of, the body, the body of desire, the libido, or life-force which Sigmund Freud said stirred the primitive cells as the sun heated the stony surface of the earth-cells which, according to him, always had the lazy, deep desire to give up striving, to return to the quiescent state from which they were roused."
