Newton, Huygens, etc. Of course that “natural philosophy” is now called 
“physical science". 

For metaphysics/theology, you need to wait … for my work :) It is hard to 
imagine something more easily refutable (in principle): compare the physical 
reality (inferred by observation) and the physical reality (deduced by 
mechanism + the math of machine’s introspection).

Lol

Note that a mathematician, and even a physicist, does not necessarily need an 
eraser, only a big trash. Well, if mechanism and/or quantum mechanics is right.
 In fact erasers (absolute erasers) probably do not exist.
