Abstract

Examines four principle questions about moral obligation raised by key philosophers: Plato asks in The Republic ‘Will a man be better off for doing his duty?’; Plato then asks ‘Ought man to do his duty?’; we may also ask ‘What is the criterion of a duty?’; and we may ask ‘What is moral obligation?’ Rejecting the last question as unreal, Prichard then argues against the connection between duty and happiness or duty and personal or general advantage. After critiquing both teleological and quasi‐teleological theories of obligation, he ends by contrasting goodness and obligation.
