Now those who take a superficial and unreflecting view of things observe the outward appearance of anything they meet, e.g. of a man, and then trouble themselves no more about him. The view they have taken of the bulk of his body is enough to make them think that they know all about him. But the penetrating and scientific mind will not trust to the eyes alone the task of taking the measure of reality; it will not stop at appearances, nor count that which is not seen among unrealities. It inquires into the qualities of the man's soul.
