““What was the Sherlock Holmes principle? ‘Once you have discounted the impossible, then whatever remains, however improbable, must be the truth.’ ” “I reject that entirely,” said Dirk sharply. “The impossible often has a kind of integrity to it which the merely improbably lacks. How often have you been presented with an apparently rational explanation of something that works in all respects other than one, which is that it is hopelessly improbable?...The first idea merely supposes that there is something we don’t know about, and...there are enough of those. The second, however, runs contrary to something fundamental and human which we do know about. We should therefore be very suspicious of it and all its specious rationality.””
