Abstract
Two criticisms of my argument in "reason and morality" were presented by christopher mcmahon (in "gewirth's justification of morality," "philosophical studies", September 1986). I reply to each criticism, Showing that mcmahon has misconstrued my use of 'ought' as action-Guiding and my universalization of the agent's rights-Judgment, As well as my concept of prudential rights. A general defect is that he has not understood how central to my argument is the agent's conative and rational standpoint
