"Man's Unhappiness, as I construe, comes of his Greatness; it is because there is an Infinite in him, with which all his cunning he cannot quite bury under the Finite... Try him with half of a Universe, of an Omnipotence, he sets to quarreling with the proprietor of the other half, and declares himself the most maltreated of men. Always there is a black spot in our sunshine: It is even, as I said, the Shadow of Ourselves."
