 To get a sense of the importance of quality of will for our interpersonal relations, note the difference in your response to one who injures you accidentally as compared to how you respond to one who does you the same injury out of “contemptuous disregard” or “a malevolent wish to injure [you]” (P. Strawson 1962 [1993: 49]). The second case is likely to arouse a type and intensity of resentment that would not be (appropriately) felt in the first case. Corresponding points may be made about positive responses such as gratitude: you would likely not have the same feelings of gratitude toward a person who benefits you accidentally as you would toward one who does so out of concern for your welfare. The focus here is on personal reactive attitudes directed toward another on one’s own behalf, but Strawson also discusses “sympathetic or vicarious” attitudes felt on behalf of others, and “self-reactive attitudes” that an agent may direct toward herself (1962 [1993: 56–7]).
