I actually like the idea of the universe of cold mathematics. I would find the idea of a non-mathematical universe sort of disappointing and hopeless.

I think a few people are assuming odd things about what I currently believe, and that's probably to be expected after a post like that.

For me now, my "faith" isn't "epistemic belief in the existence of a particular God", but "provisional trust in the hypothesis of an admittedly poorly expressed ideal". This is no different than provisional trust in any other hypothesis, except inasmuch as I don't have a nice clean experiment to falsify it. I'm just living my life and seeing how it goes. It's not impossible that I will find that it goes badly enough to make me abandon some of the heuristics I currently adopt.
