Quotes About Infinitesimals

Newton had been the first to learn how to pin down the mysterious infinitesimals that held the key to explaining motion.

Only by taking infinitesimally small units for observation (the differential of history, that is, the individual tendencies of men) and attaining to the art of integrating them (that is, finding the sum of these infinitesimals) can we hope to arrive at the laws of history.

Only by assuming an infinitesimally small unit for observation - a differential of history (that is, the common tendencies of men) - and arriving at the art of integration (finding the sum of the infinitesimals) can we hope to discover the laws of history.
