"The `Why?' cannot, and need not, be put into words. Those for whom a child's mind is a sealed book, and who see no divinity in a child's smile, would read such words in vain: while for any one that has ever loved one true child, no words are needed. For he will have known the awe that falls on one in the presence of a spirit fresh from God's hands, on whom no shadow of sin, and but the outermost fringe of the shadow of sorrow, has yet fallen: he will have felt the bitter contrast between the haunting selfishness that spoils his best deeds and the life that is but an overflowing love--for I think a child's first attitude to the world is a simple love for all living things: and he will have learned that the best work a man can do is when he works for love's sake only, with no thought of name, or gain, or earthly reward. No deed of ours, I suppose, on this side the grave, is really unselfish: yet if one can put forth all one's powers in a task where nothing of reward is hoped for but a little child's whispered thanks, and the airy touch of a little child's pure lips, one seems to come somewhere near to this."
