"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.
