Nobody can imagine how nothing could turn into something. Nobody can get an inch nearer to it by explaining how something could turn into something e… - G. K. Chesterton

It is the custom in our little epoch to sneer at the middle classes. Cockney artists profess to find the bourgeoisie dull; as if artists had any business to find anything dull. Decadents talk contemptuously of its conventions and its set tasks; it never occurs to them that conventions and set tasks are the very way to keep that greenness in the grass and that redness in the roses--which they have lost forever.

"Angels can fly because they can take themselves lightly. This has been always the instinct of Christendom, and especially the instinct of Christian art. Remember how Fra Angelico represented all his angels, not only as birds, but almost as butterflies. Remember how the most earnest mediaeval art was full of light and fluttering draperies, of quick and capering feet. It was the one thing that the modern Pre-raphaelites could not imitate in the real Pre-raphaelites. Burne-Jones could never recover the deep levity of the Middle Ages. In the old Christian pictures the sky over every figure is like a blue or gold parachute. Every figure seems ready to fly up and float about in the heavens. The tattered cloak of the beggar will bear him up like the rayed plumes of the angels. But the kings in their heavy gold and the proud in their robes of purple will all of their nature sink downwards, for pride cannot rise to levity or levitation. Pride is the downward drag of all things into an easy solemnity. One "settles down" into a sort of selfish seriousness; but one has to rise to a gay self-forgetfulness. A man "falls" into a brown study; he reaches up at a blue sky. Seriousness is not a virtue. It would be a heresy, but a much more sensible heresy, to say that seriousness is a vice. It is really a natural trend or lapse into taking one's self gravely, because it is the easiest thing to do. It is much easier to write a good Times leading article than a good joke in Punch. For solemnity flows out of men naturally; but laughter is a leap. It is easy to be heavy: hard to be light. Satan fell by the force of gravity."

The point is not that this world is too sad to love or too glad not to love; the point is that when you do love a thing, its gladness is a reason for loving it, and its sadness a reason for loving it more.
