Sometimes the writing is a bit dense, but the story is fascinating. HIstory is a wiggly thing, and shifts over time. It has been a tradition to glorify the achievements of someone over some of their less wonderful qualities. This is very much the case with Newton; he is been credited with all sorts of things that may, in fact, have not been his at all. And worse, he manipulated many situations to his benefit, and not the benefit of science. Kind of the JR Ewing of 17th century science.
While there is no denying his influence and impact, it is truly humanizing to see how devious, dishonest and venal he could be at the same time. As despicable as he could be, his ambition being his primary driver, his drive no doubt dragged science along with him, inspiring energetic progress.
The history of science is so much richer with the added dimensions of personality and moral corruption, this book adds quite a bit to this.
