 On the other hand, if we assume that the speaker is a non-BIV speaking English, then premises (A*) and (B*) would both be true, as would the conclusion (C). However, the argument in question, though sound, would blatantly beg the question. For in order for the speaker to have warrant that premises (A*) and (B*) are both true in the relevant senses, warrant must already be available to the speaker of (A*) and (B*) that she is a non-BIV speaking English.
