Why, how do you do?

[Purple Rabbit]

This is not just a joke. This is subject in philosophical debate. Starting with Plato (as far as I can trace it) numerous great minds have wrestled with it. Mathematics may be a system which humans use to quantify reality, mathematical concepts are not part of reality. You can't find perfect circles in nature. So mathematics is not necessarily a reality within nature but just an aspect of our models of nature. I hope you can grasp this and its implication and lower that "nothing-supernatural-in-my-backyard" defence shield of yours. And yes I tickled you somewhat to get to this point. If mathematical concepts aren't part of the natural world and if you allow there to be a strict dichotomy between natural and supernatural, these concepts are part of the supernatural. I challenge you to refute this since I think those arguments should be baggage of every atheist debater. So to assure you, I contend that I have played the devil's advocate here somewhat, but I assure you your quest is mine.
