Chapter XXXI In What Does Scepticism Differ From the Cyrenaic Philosophy?
Some say that the Cyrenaic School is the same as the Sceptical, because that school also claims to comprehend only conditions of mind. It differs, however, from it, because, while the former makes pleasure and the gentle motion of the flesh its aim, we make ἀταραξία ours, and this is opposed to the aim of their school. For whether pleasure is present or not, confusion awaits him who maintains that pleasure is an aim, as I have shown in what I said about the aim. And then, in addition, we suspend our judgment as far as the reasoning with regard to external objects is concerned, but the Cyrenaics pronounce the nature of these inscrutable.
