 A disposition to too readily forgive may be symptomatic of a lack of self-respect, or indicative of servility, ordinarily viewed as moral infirmities or vices (Novitz 1998). This recalls Aristotle’s idea that the person deficient in appropriate anger is “unlikely to defend himself” and “endure being insulted” and is for this reason a “fool” (Nicomachean Ethics, 1126a5), Kant’s notion that a person who fails to become angry at injustices done to him lacks dignity and self-respect (Kant [c. 1770–1794] 1997, cf. Sussman 2005; Ware 2014), and Hume’s assertion that since anger and hatred are “inherent in our very frame and constitution” the lack of such feelings is sometimes evidence of “weakness and imbecility” ([1740] 1958: 605). That interpersonal forgiveness does not always serve morally laudable aims suggests that a general account of the criteria for justified and morally permissible or even obligatory forgiveness is needed to distinguish appropriate from inappropriate forgiving.
