The technique in its full form. Book XII names the same operation three times: folded up in 12.10 (ὕλη, αἴτιον, ἀναφορά), as one item in the checklist of 12.8, and here unfolded, with a fourth member added. What is added is χρόνος: "the time within which this will have to cease." The analysis stops being merely logical and becomes temporal as well: a thing has a term, and the term belongs to its definition as much as its matter and its cause.

Εἰς τὸ πᾶν. "At the whole of it" — not "at every thing" but at the entire object: one is to look not at the side it has turned toward you but at all of it. The same move is in 3.11: to see it ὅλον δι’ ὅλων διῃρημένως, "whole, throughout, divided out."

What exactly is taken apart. Not the thing, but αὐτὸ ἐκεῖνο τὸ τὴν TERMφαντασίαν σοι ποιοῦν — "that very thing which is producing the impression in you." The distinction is fine and it matters: the work is done not on the external object but on its source in you, on where the picture came from. Hence the verb ἀναπτύσσειν — "to unroll," as one unrolls a scroll: not to break up but to spread out and read.

Why the entry has no finite verb. Like 12.7, 12.8 and 12.10, it is built on infinitives alone: ὁρᾶν, ἀναπτύσσειν. Book XII speaks ever more briefly, and this is not fatigue but a sign of completion: the techniques are no longer explained, only called over by name. The governing discipline is assent.
