  Verdict: the Skeptic does have beliefs. He assents to certain appearances, namely those that aren’t accompanied by equal and opposing appearances. When he assents to those appearances, he is not endorsing them as being the correct ones in the light of this or that theory, or in the light of this or that reason for assenting, but merely passively responding to their pull. In I 13 Sextus dresses this point up in Stoic garb, presumably in order to send the message that the Stoics have to acknowledge the existence of the kinds of belief the Skeptic has. And the examples of beliefs that the Skeptic would end up with are indeed the ones that Frede gives, such as me believing now that it is day, on the basis of having a (perceptual) impression that it is light outside, an impression which is not countermanded by any countervailing impressions and which exerts a pull all of its own towards assent.
