QUESTION-BEGGING ARGUMENTS, which crop up quite often in discussions of controversial issues, constitute serious obstacles to progress in rational resolution of conflicts of opinion. With a modicum of instruction, conscientious disputants learn to detect question-begging steps in their opponents' manoeuvres, and to avoid such fallacious arguments in their own contributions. Yet theorists have had a surprisingly difficult time providing a satisfactory explication of the fallacy of begging the question. In a previous paper, I criticized a number of recent philosophical stances on the fallacy, and formulated a view of my own. 1 David Sanford showed in a reply that my account was vague and incomplete in several respects. 2 In light of his valuable criticisms, I will now attempt to provide a clear, complete and concise reformulation of my theory.
