The life of Isaac Newton falls into two halves, and the main problem for Newton studies is how to fit them together. In the first half he was a sulky Cambridge mathematician who, at the age of 44, astonished the world with a work of natural science that was soon recognised as one of the greatest books ever written. In the second he was a sleek London gentleman wallowing in power, wealth and prestige and devoting his intellectual energy to esoteric studies of the Bible. How could they be the same person?
