Sextus Empiricus Pyrrhoniae Hypotyposes 3.18.131

[131] The Peripatetics ¹ assert that place is ‟the limit of what encloses in so far as it encloses,” so that my place is the surface of the air that forms a mould round my body. But if this is place, the same thing will both be and not be. For when the body is about to become in a certain place, then, inasmuch as nothing can become in what is non-existent, the place must be pre-existent in order that the body may in this way become in it, and consequently the place will exist before the-body-in-the-place becomes therein. But inasmuch as it consists in the moulding of the surface of what encloses round the thing enclosed, place cannot be already subsisting before the body becomes within it, and therefore it will not be in existence then. But it is absurd to say that the same thing both is and is not; therefore place is not ‟the limit of what encloses in so far as it encloses.”
