"…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."
