That's not really true about Newton by the way. Newton most likely believed he did not have a convincing argument he wanted to put his name to or advance that wouldn't also drag him into yet another round of having to deal with someone like Robert Hooke. At that point of his life, his ambition was greatly lessened and his success somewhat assured. There is firm evidence he had at least 3 serious views (and one fairly archaic one not many want to talk about) on the cause of physical gravitation. It is only the "modernists" who need for Newton be be not beholden to any of them that elevate and reiterate "Hypotheses non fingo" to some sort of rallying cry as if he had it tattooed on his torso.
