So it seems like what we were actually talking about here was how thoroughly God could convince a human of His existence, and you suggested he could just raise your faith level directly.

Here's the problem I have with that: I don't know about Odin, but the YHWH we were raised with doesn't (could, but doesn't) ever do that. I wouldn't really call it faith if you have no choice in the matter.

But I recognize that free agency is a very important tenet of my religion and important to my understanding of the universe given that my religion is correct. (I still don't quite understand free choice, which I'll have to figure out sometime in the next few years, but that's my own issue.) Thus, a radically different deity is at odds with my view of the universe. This probably means that I ought to go looking for radically different deities which will challenge my universe, but for now I don't know of any (except maybe simulation hypotheses, which I like a lot).

But for the purposes of this discussion—which, remember, was only about how spectacular a manifestation it would take to make you believe—I said it would be easier to stick to a God that doesn't intervene to the point of directly tampering with our neurons. You had a problem with this. OK, sorry—let's also think about a fundamentally different God.

I think that an effectively all-powerful being could easily just reach in and rearrange our circuits such that we know it exists. Sure it could happen. As I think I told someone, I don't see why—having seven billion mindless minions would get old after a while—but I have no right to go questioning the motives of a deity, especially one that's radically different from the one I'm told I'm modeled after.

I'm sorry, I never meant to dismiss the possibility of radically different religions. You're right, that would be awfully silly coming from me.

Now then.

You seemed to be arguing a while back that our precommitments to "the way we think about things" were not sufficient grounds to reject uncomfortable or difficult ideas, which is a position I can respect, though I think it's importantly though subtly false.

This sounds very interesting, what do you mean?
