Man is more himself, man is more manlike, when Joy is the fundamental thing in him, and Grief the superficial. Melancholy should be an innocent interlude, a tender and fugitive state of mind; Praise should be the permanent pulsation of the soul. Pessimism is at best an emotional half-holiday; Joy is the uproarious labor by which all things live? Christianity satisfies suddenly and perfectly man's ancestral instinct for being the right way up; satisfies it supremely in this, that by its creed Joy becomes something gigantic, and Sadness something special and small.
