Who is Tom Bombadil?

Tom Bombadil is just as he is. Just an odd ‘fact’ of that world. He won’t be explained, because as long as you are (as in this tale you are meant to be) concentrated on the Ring, he is inexplicable. But he’s there – a reminder of the truth (as I see it) that the world is so large and manifold that if you take one facet and fix your mind and heart on it, there is always something that does not come in to that story/argument/approach, and seems to belong to a larger story. But of course in another way, not that of pure story-making, Bombadil is a deliberate contrast to the Elves who are artists. But B. does not want to make, alter, devise, or control anything: just to observe and take joy in the contemplating the things that are not himself. The spirit of this earth made aware of itself. He is more like science (utterly free from technological blemish) and history than art. He represents the complete fearlessness of that spirit when we can catch a little of it. But I do suggest that it is possible to fear (as I do) that the making artistic sub-creative spirit (of Men and Elves) is actually more potent, and can ‘fall’, and that it could in the eventual triumph of its own evil destroy the whole earth, and Bombadil and all.
