" I shall explain it, Nicolas," Isaac said. "Daniel has done all the explaining we may justly require of him. He means—but is unwilling to say—that your theory of gravity is nonsense and that it has weakened my position vis-à-vis Leibniz. He probably refers also to your claim to be a co-inventor of the calculus, which is, I am sorry to say, perfectly false. Perhaps he has also in mind your pretensions of becoming a medical doctor and curing thousands with a new patent-medicine, and your fanciful interpretations of the Bible, and strange prophecies drawn therefrom."
