But the next approach told a new development.
Henceforth, whatever our philosopher says about Matter will apply to extension and to extension alone. It cannot be apprehended by sight, nor by hearing, nor by smell, nor by taste, for it is neither colour, nor sound, nor odour, nor juice. Neither can it be touched, for it is not a body, but it becomes corporeal on being blended with sensible qualities. And, in a later essay, he describes it as receiving all things and letting them depart again without retaining the slightest trace of their presence.483 Why then, it may be asked, if Plotinus meant extension, could he not say so at once, and save us all this trouble in hunting out his meaning? There were very good reasons why he should not. In the first place, he wished to express himself, so far as possible, in Aristotelian phraseology, and this was incompatible with the reduction of Matter to extension. In the next place, the idea of an infinite void had been already appropriated by the Epicureans, to whose system he was bitterly opposed. And, finally, the extension of ordinary327 experience had not the absolute generality which was needed in order to bring Matter into relation with that ultimate abstraction whence, like everything else, it has now to be derived.
It was certainly not apparent, on the face of it, how the thing was to be done, but the captain explained. "I've been stationed here, you know, and I know the roads. We are about a half a mile or more from where the Stanton road to the railway crosses the lava. It is narrow and rough, and about from three-quarters of a mile to a mile wide, but cavalry can go over it without any trouble. I can take my troop over, and then the Indians will be hemmed in between us. We might capture the whole band."
