can you say where you got this idea?

"...和牛顿时代又有不同，牛顿是根据自然现象抽象出的理论，而老爱呢，他是从纸上推演出了自己的世界，一个可能完全不能用人类的感官去体验的世界。这个世界可能不是一种“存在”，如果我们把“存在”作狭义的解释的话。我们之所以接受它，主要因为它的整个推演过程在假定的前提下，符合既有的物理和数学的逻辑。爱因斯坦时代证明人类的思维可以完全依据符号系统自身的逻辑来演绎，而不需要实际的观察和体验"

I sense that this is correct but I want more proof. To me this shows exactly how the human cognitive process evolved: first from the side of "Empiricism", later from side of "metaphysics".

2 the above, if correct, implies that Einstein's general relativity is NOT something "accidental", which might get overthrown someday as you mentioned, because it is a more generic system which made the Newtonian physics as a early example in the history of physics. In this sense, the general relativity theory will only get improved but not replaced.

my 2 cents
