All knowledge is local, all truth is partial. No truth can make another truth untrue. All knowledge is part of the whole knowledge. Once you have seen the larger pattern, you cannot go back to seeing the part as the whole.
Ursula K. Le GuinCertainly the effort to remain unchanged, young, when the body gives so impressive a signal of change as the menopause, is gallant; but it is a stupid, self-sacrificial gallantry, better befitting a boy of twenty than a woman of forty-five or fifty. Let the athletes die young and laurel-crowned. Let the soldiers earn the Purple Hearts. Let women die old, white-crowned, with human hearts.
Ursula K. Le Guin
