"I have long been impressed by the fact that Isaac Newton, besides being the greatest of scientific geniuses, was also one of the most singular and fascinating characters of which we have any record. This Life of Isaac Newton is an attempt to exemplify this point of view. The conception of Newton here worked out was first published by me in the Isaac Newton bi-centenary article which appeared in the Times Literary Supplement in 1927"--Prefatory note.
