Don't you think that the person who is likely to succeed in this attempt most perfectly is the one who approaches each object, as far as possible with the unaided intellect, without taking account of any sense of sight in his thinking, or dragging any other sense into his reckoning - the man who pursues the truth by applying his pure and unadulterated thought to the pure and unadulterated object, cutting himself off as much as possible from his eyes and ears and virtually all the rest of his body, as an impediment which by its presence prevents the soul from attaining to truth and clear thinking? Is not this the person, Simmias, who will reach the goal of reality if anyone can?
