It is impossible for the soul to become similar to sense-objects (in order to grasp them), by remaining pure. How indeed could a point become similar to a line? The intelligible line itself could not become conformed to the sense-line, any more than intelligible fire to the sense-fire, or the intelligible man to the sense-man. Nature herself which begets man could not be identical with the begotten man. The isolated soul, even if she could grasp sense-objects, will finish by applying herself to the intuition of intelligible objects, because, having nothing by which to grasp the former, she will let them escape. Indeed, when the soul perceives from far a visible object, although only the form reaches her, nevertheless what first began by being for her indivisible, finally constitutes a subject, whether it be color or a figure, whose size is determined by the soul. [Ennead IV,4 (28) 23]
