Readers and scholars who want to know what Newton really said, as opposed to how one might prove the same things in a different way, will find the full proofs nowhere else. I cannot emphasize too strongly what an achievement it is. Taking Newton in his own terms, it insists on the full rigor of the demonstrations and does not hesitate to point out where full rigor appears to be lacking. Students are not the only ones who can profit from the exercise. This is particularly interesting because Newton's geometric style informs our geometric and physical intuition in a way which is complementary to the understanding achieved via analytical tools.
Historians of science have a great deal to learn from it.
