  Barnes and Burnyeat have the same goal: to deny that any utterances the Skeptic makes which have the form ‘X appears F’ commit the Skeptic to having any beliefs. In other words, they attempt to show that assenting to the ‘feelings forced upon them by appearances’ (I 13) need not involve having a belief in our sense of the term (even though Sextus says that this is a way of having a dogma). It is important to see that Barnes and Burnyeat do not arrive at this position by interpreting I 13 alone; rather they have an argument that the Skeptic can’t have any beliefs, and they interpret I 13 in the light of that. That argument is sketched below (section 4.1), since it turns on the use they make of Sextus’ discussion of the criterion of truth (which occupies a large part of PH II and all of M VII).
