 Note that there can be no issue of question-begging in an anti-skeptical argument like this. First, it is not the person to whom the skeptical argument is being addressed who is assuming premise (1) of both (SA) and (AS). Rather, it is the skeptic who is making that assumption. Second, the person being addressed can be taken to be assuming premise (1) merely for the sake of conditional proof. That is, she can be taken to be arguing merely for the conclusion that if premise (1) is true then premise (3) is false, so that at least one of argument (SA)’s premises is false.
