Applicability of Maths to the Universe

[Belacqua]

easily mappable to the real world.

It's all really puzzling. Way too hard for me to understand. 

Unfortunately William Lane Craig has made it his thing, but far more respectable people discuss the same issue. Clearly math has some applicability to the material world -- yet also has its own non-material existence that doesn't map. Exactly how the two things can be compatible is tricky.

Recently -- maybe you saw -- a very unpleasant Christian was here and brought up a similar issue. It was too bad that he was so nasty, because it really is a fascinating topic. And it's one that we can work on without reference to Craig.

Here is Penrose on the topic. As I recall in this video he just says that he doesn't know how the math-world and the material world go together, exactly.

And as I told the nasty guy, Penrose is here quoting Popper, whose Three Worlds system seems very useful to me.

listen here my young apprentice, what WLC is doing is pushing for platonic realism and substance dualism in order to sneak in the idea that his god exists without evidence

This is why it's far better to ignore WLC and read the good people who raise the same issue.
