"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."
~G.K. Chesterton: Orthodoxy, Chap. VII─The Eternal Revolution.
