There is a thing called knowledge of the world, which people do not have until they are middle-aged. It is something which cannot be taught to younger people, because it is not logical and does not obey laws which are constant. It has no rule. Only, in the long years which bring women to the middle of life, a sense of balance develops. You can't teach a baby to walk by explaining the matter to her logically - she has to learn the strange poise of walking by experience. In some way like that, you cannot teach a young woman to have the knowledge of the world. 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 - if women ever do hope this - 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.
