 On (A), Murdoch delineates a broader notion of moral agency than that involved in reasons internalism and the perception of or sensitivity to action-guiding reasons within situations. She seeks to demonstrate a form of moral agency that takes place solely in the mind of the agent with no expression in her behavior in the public world. She does so through an extended example in IP, which serves other purposes as well (especially the importance of the inner life for morality, against  point 5  [the inner life is not very important for morality]), and is extensively cited in the secondary literature. The example is of M, the mother-in-law of D. Throughout D’s marriage to M’s son, M has viewed D as “pert and familiar, insufficiently ceremonious, brusque, sometimes positively rude, always tiresomely juvenile”. She feels her son has “married beneath him” (IP: 17/312). M behaves toward D without revealing her real opinions and feelings. Murdoch highlights this feature by imagining that D moves away or dies, and that M therefore comes to have no opportunity to engage in behavior directed at D.
