Indeed it doesn't, nor did I see him pretend that it does... As you know, the PoR is included in Newtonian mechanics (just in other words).
I thought you were saying that Newton was arguing for an absolute rest frame.

I don't understand, then. As I said, I thought you were saying that Newton was making arguments in favor of an absolute standard of rest. If he was only making an argument in favor of an absolute standard for acceleration, then that's not news. Yes, inertial frames are special.
