All that causes one man to differ from another is a very slight thing. What is it that is the origin of beauty or ugliness, health or weakness, ability or stupidity? A slight difference in the organs, a little more or a little less bile. Yet this more or less is of infinite importance to men; and when they think otherwise they are mistaken.
All our distinctions are accidental; beauty and deformity, though personal qualities, are neither entitled to praise nor censure; yet it so happens that they color our opinion of those qualities to which mankind have attached responsibility.
