Mathmatics, Physics, Chemestry. If you asked some reputable scientists about them, and the differences between, hopefully what you would get is that what we have discovered in math and science is just a language that describes what is. It is what we see reflected in nature, it is not nature.
Well actually every science except mathematics maybe, but mathematics is the science of our own minds and nothing else (sort of like meta-psychology, in a weird way...), and if we can't accept that our own minds are capable of forming a proper language of describing their own selves then to hell with everything.
edit:
As the Lyrics of the song Freewill by Rush go:
You can choose a ready guide in some celestial voice
If you choose not to decide, you still have made a choice
You can choose from phantom fears and kindness that can kill
I will choose a path that's clear
I will choose freewill
That doesn't mean anything. It's still just saying "AHA you did something - you have chosen to do it!" That's precisely what we're discussing here - whether you actually
have chosen to do what you did or not. You could have as well just said "I choose because I do" or even better "circular reasoning works because circular reasoning works" instead of posting some lyrics to make it sound cooler.
