Independence . . .

     Tomorrow, July 4, the US celebrates "Independence" Day and I am reflecting on the following quote by Albert Einstein (1879-1955):

     How can it be that mathematics, 
     being after all a product of human thought 
          . . . independent of experience, 
     is so admirably appropriate
     to the objects of reality?

(found here, along with lots of Einstein quotes) 

I am trying to decide to what degree I agree with Einstein's words.
