  Barnes points out that Sextus often lays out an argument and then says that the skeptic will suspend judgment as far as that argument goes (ὅσον ἐπὶ τούτῳ); the idea is that Sextus uses that formula to capture the fact that if such-and-such an argument is all you had to go on, you suspend judgment. (See Frede 1979: 10–11; 1984: 133; and Brunschwig 1990 for more on this phrase.)
