I was surprised to find out that Newton had a strong hand in philosophy as well as mathematics; his hard determinism, and like-ideas, were some of what Kant critiqued in his writings. I think this is a very good example of a multi-faceted contribution from a person, since most people specialized their minds to one discipline, so it should definitely be preserved. I would love to know more of Lieibnitz's side of the argument for his calculus, maybe why he thought Newton's publication was a tad, dare I say, derivative.
