So far from it being irreverent to use silly metaphors on serious questions, it is one’s duty to use silly metaphors on serious questions. It is the test of one’s seriousness. It is the test of a responsible religion or theory whether it can take examples of pots and pans and boots and butter-tubs. It is a test of a good philosophy whether you can defend it grotesquely. It is the test of a good religion whether you can joke about it.
~G.K. Chesterton, from All Things Considered
