How could there have been a group of philosophers who said they really were skeptics? How could they have claimed to suspend judgment about all non-evident matters which were presented to them and to have gone their way adoxastös (without belief) by (as they said) “following the appearances” (PH 1.23)? That is the question I would like to answer.
