On the side of angels

[In today's reading, Lewis assumes we'll know the oft-told story of how angels appeared, protecting British troops in their retreat from Mons, France, on the 26th August 1914.]

Intimate conversation elicits from almost every acquaintance at least one episode in his life which is what he would call ‘queer’ or ‘rum’. No doubt most stories of miracles are unreliable; but then, as anyone can see by reading the papers, so are most stories of all events. Each story must be taken on its merits: what one must not do is to rule out the supernatural as the one impossible explanation. Thus you may disbelieve in the Mons Angels because you cannot find a sufficient number of sensible people who say they saw them. But if you found a sufficient number, it would, in my view, be unreasonable to explain this by collective hallucination. For we know enough of psychology to know that spontaneous unanimity in hallucination is very improbable, and we do not know enough of the supernatural to know that a manifestation of angels is equally improbable. The supernatural theory is the less improbable of the two. When the Old Testament says that Sennacherib’s invasion was stopped by angels (2 Kings 19:35), and Herodotus says it was stopped by a lot of mice who came and ate up all the bowstrings of his army, an open-minded man will be on the side of the angels. Unless you start by begging the question, there is nothing intrinsically unlikely in the existence of angels or in the action ascribed to them. But mice just don’t do these things.
