Happiness is a mystery like religion, and should never be rationalized. Suppose a man experiences a really splendid moment of pleasure. I do not mean something connected with a piece of enamel, I mean something with a violent happiness in it—an almost painful happiness. A man may have, for instance, a moment of ecstasy in first love, or a moment of victory in battle. The lover enjoys the moment, but precisely not for the moment's sake. He enjoys it for the woman's sake, or his own sake. The warrior enjoys the moment, but not for the sake of the moment; he enjoys it for the sake of the flag. The cause which the flag stands for may be foolish and fleeting; the love may be calf-love, and last for a week. But the patriot thinks of the flag as eternal; the lover thinks of his love as something that cannot end. These moments are filled with eternity; these moments are joyful because they do not seem momentary. Once look at them as moments after Pater's manner, and they become as cold as Pater and his style. Man cannot love mortal things. He can only love immortal things for an instant.
