Sextus Empiricus Pyrrhoniae Hypotyposes 3.7.50

[50] If then Incorporeality is the privation of Body, and when states are not apprehended it is impossible for the privations of them to be apprehended, and it has been proved that Body is inapprehensible, Incorporeality also will be inapprehensible. Moreover, it is either sensible or intelligible. And if it is sensible, it is inapprehensible because of the variance amongst animals and men, the senses and the circumstances, and owing to the admixtures and all the other things we have previously described in our exposition of the Ten Tropes. ¹ If, again, it is intelligible, since the apprehension of sensibles, which is supposed to form the starting-point from which we attain to the intelligibles, ² is not immediately given, neither will the apprehension of the intelligibles be given immediately, nor, consequently, that of Incorporeality.
