 We might think (and Broad did think) that Prichard cannot be right to say that there are only two sorts of ‘ought’: the moral one, full-blown, and the means-end one which only has force for those who have adopted the end, and only says that if they don’t take this means they will not achieve that end. I myself would want to appeal to the normative force of advice. But Prichard’s main point might survive such a response. For all that he needs to establish is that in order to show that we have a moral duty to write the begging letters we need to do more than show that it is the best or only means to something which we have a moral duty to aim at.
