Objective Consequentialism and the Rationales of ‘ “Ought” Implies “Can” ’

This paper argues that objective consequentialism is incompatible with the rationales of ‘ “ought” implies “can” ’ – with the considerations, that is, that explain or justify this principle. Objective consequentialism is the moral doctrine that an act is right if and only if there is no alternative with a better outcome, and wrong otherwise. An act is obligatory if and only if it is wrong not to perform it. According to ‘ “ought” implies “can” ’, a person is morally obligated to φ only if the person can φ. The rationales of ‘ “ought” implies “can” ’ include considerations related to intuitive plausibility, action‐guidance, blameworthiness and fairness, and the nature of practical reasons. 1
