M and D: the mother-in-law's private revision
A mother, M, finds her son's wife D pert, vulgar and juvenile, yet behaves perfectly toward her throughout. Over time, with no change in outward conduct and even after D has moved away or died, M deliberately looks again and comes to see D as refreshingly simple, spontaneous and delightfully youthful. Murdoch uses the case to show that M has done real moral work that is purely inner and invisible, which an account of morality as observable choice and action cannot register.
