We used to be told in the nursery that if a man were to bore a hole through the centre of the earth and climb continually down and down, there would come a moment at the centre when he would seem to be climbing up and up. I do not know whether this is true. The reason I do not know whether it is true is that I never happened to bore a hole through the centre of the earth, still less to crawl through it. If I do not know what this reversal or inversion feels like, it is because I have never been there. And this also is an allegory. It is certain that the writer, it is even possible that the reader, is an ordinary person who has never been there. We cannot follow St. Francis to that final spiritual overturn in which complete humiliation becomes complete holiness or happiness, because we have never been there. I for one do not profess to follow it any further than that first breaking down of the romantic barricades of boyish vanity, which I have suggested in the last paragraph. And even that paragraph, of course, is merely conjectural, an individual guess at what he may have felt; but he may have felt something quite different. But whatever else it was, it was so far analogous to the story of the man making a tunnel through the earth that it did mean a man going down and down until at some mysterious moment he begins to go up and up. We have never gone up like that because we have never gone down like that; we are obviously incapable of saying that it does not happen; and the more candidly and calmly we read human history, and especially the history of the wisest men, the more we shall come to the conclusion that it does happen. Of the intrinsic internal essence of the experience I make no pretence of writing at all. But the external effect of it, for the purpose of this narrative, may be expressed by saying that when Francis came forth from his cave of vision, he was wearing the same word "fool" as a feather in his cap; as a crest or even a crown. He would go on being a fool; he would become more and more of a fool; he would be the court fool of the King of Paradise.
