She has to be left to the experience of the years. And then, when she is beginning to hate her used body, she suddenly finds that she can do it. She can go on living, not by principle, not by deduction, not by knowledge of good and evil, but simply by a peculiar and shifting sense of balance which defies each of these things often. She no longer hopes to live by seeking the truth [...] but continues henceforth under the guidance of a seventh sense. Balance was the sixth sense, which she won when she first learned to walk, and now she has the seventh one--knowledge of the world.
