Human understanding, he wrote (seemingly following David Hume), is its own revelation, and: [h]as made it certain that two and one make three; and that one is not three; nor can three be one…. Miracles or Prophecies might frighten us out of our Witts; might scare us to death; might induce Us to lie; to say that We believe that 2 and 2 make 5. But we should not believe it. We should know the contrary.
