Oh I agree. I believe there is a great amount of correlation
   between the actions of humans to describe the world and
   mathematize the patterns which seem to correlate well with our
   cognitive processes, and also allow us to build nifty toys that
   work, like computers, develop nifty systems like logic that work
   like "machines on paper" and such. They also happen to work very
   well at this point in time of the history of the Universe.

   From a pragmatic standpoint, what we consider to be objective
   reality, "might as well be". It's close enough to get stuff
   done.

   To me, it's all heuristics. In short: rule of thumb. Close
   enough for now.
