I think seriously, on the whole, that the more serious is the discussion the more grotesque should be the terms. For this, as I say, there is an evident reason. For a subject is really solemn and important in so far as it applies to the whole cosmos, or to some great spheres and cycles of experience at least. So far as a thing is universal it is serious. And so far as a thing is universal it is full of comic things. If you take a small thing, it may be entirely serious: Napoleon, for instance, was a small thing, and he was serious: the same applies to microbes. If you isolate a thing, you may get the pure essence of gravity. But if you take a large thing (such as the Solar System) it must be comic, at least in parts. The germs are serious, because they kill you. But the stars are funny, because they give birth to life, and life gives birth to fun. If you have, let us say, a theory about man, and if you can only prove it by talking about Plato and George Washington, your theory may be a quite frivolous thing. But if you can prove it by talking about the butler or the postman, then it is serious, because it is universal. 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 from pots and pans and boots and butter-tubs. It is the 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.
