Certainly we could not delight in that so courtly thing, the poetry of light love, if it were sad; for only when we are gay over a thing, and can play with it, do we show ourselves its master, and have minds clear enough for strength. The raging fire and the destructive sword are portions of eternity, too great for the eye of man, wrote Blake, and it is only before such things, before a love like that of Tristan and Iseult, before noble or ennobled death, that the free mind permits itself aught but brief sorrow. That we may be free from all the rest, sullen anger, solemn virtue, calculating anxiety, gloomy suspicion, prevaricating hope, we should be reborn in gaiety. Because there is submission in a pure sorrow, we should sorrow alone over what is greater than ourselves, nor too soon admit that greatness, but all that is less than we are should stir us to some joy, for pure joy masters and impregnates; and so to world end, strength shall laugh and wisdom mourn. III In life courtesy and self-possession, and in the arts style, are the sensible impressions of the free mind, for both arise out of a deliberate shaping of all things, and from never being swept away, whatever the emotion, into confusion or dulness. The Japanese have numbered with heroic things courtesy at all times whatsoever, and though a writer, who has to withdraw so much of his thought out of his life that he may learn his craft, may find many his betters in daily courtesy, he should never be without style, which is but high breeding in words and in argument. He is indeed the Creator of the standards of manners in their subtlety, for he alone can know the ancient records and be like some mystic courtier who has stolen the keys from the girdle of time, and can wander where it please him amid the splendours of ancient courts.
