 To understand moral responsibility properly, Strawson invited his reader to consider the reactive attitudes one has towards another when she recognizes in another’s conduct an attitude of ill will. The reactions that flow naturally from witnessing ill will are themselves attitudes that are directed at the perpetrator’s intentions or attitudes. When a perpetrator wrongs a person, she, the wronged party, typically has a personal reactive attitude of resentment. When the perpetrator wrongs another, some third party, the natural reactive attitude is moral indignation, which amounts to a “vicarious analogue” of resentment felt on behalf of the wronged party. When one is oneself the wronging party, reflecting upon or coming to realize the wrong done to another, the natural reactive attitude is guilt.
