Humility One Sign of Greatness

I believe the first test of a truly great man is his humility. I do not mean by humility doubt of his own power, or hesitation in speaking his opinions; but a right understanding of the relation between what he can do and say, and the rest of the world's sayings and doings. All great men not only know their business, but usually know that they know it; and are not only right in their main opinions, but they usually know that they are right in them; only they do not think much of themselves on that account. The slightest manifestation of jealousy or self-complacency is enough to mark a second-rate character of the intellect.—Ruskin
