Sextus Empiricus Pyrrhoniae Hypotyposes 1.15.170

[170] The matter proposed is either a sense-object or a thought-object, but whichever it is, it is an object of controversy; for some say that only sensibles are true, others only intelligibles, others that some sensible and some intelligible objects are true. ¹ Will they then assert that the controversy can or cannot be decided? If they say it cannot, we have it granted that we must suspend judgement; for concerning matters of dispute which admit of no decision it is impossible to make an assertion. But if they say that it can be decided, we ask by what is it to be decided.
