 (1) Moral reaction responsibility is relevant when we ask certain positive or negative moral reactions to a person – such as blame, resentment, praise, or gratitude – are appropriate. Intuitively, “what a person has done makes such reactions appropriate only if the person was responsible for behaving in this way” (Scanlon 2015, pp. 89–90). Scanlon originally called this “responsibility as attribution”, but he has come to prefer the label “moral reaction responsibility”.
