I'm trying to understand how Newton formulated his corpuscular theory of light when he was surrounded by evidence of light's wave-light properties. Specifically, the effect that we now call Newton's rings, which he discusses in Optiks.

Newton discusses the Rings in Part 1, Book 2 of Optiks (page 160 of this pdf), but having read it, and various other parts, I can't figure out how he jumps from the observation of refraction to the conclusion that light must be made out of corpuscles, and not a wave-like phenomena.
