Good episode. I like Kuhn, but he, like just about everyone, is still stuck in the notion that those are the only three options, and that we must choose one of them.

“If we are asking the wrong question, what would be a better question?”

If I understood the speaker correctly, we don’t yet know how to formulate that better question. And I agree with that, but a good preliminary question in the meantime would be... what is God’s nature? What exactly is this thing we are believing in or not believing in? And if we don’t even know if it exists, how can we be certain what its nature is?

“If a god is unlikely to exist, or its existence has no effect on our own, is pursuit of the unknowable still a meaningful exercise, or a waste of time?”

Given your conditions I’d say the latter. But there is room for discussion on those conditions.

“If a god did exist, given we can know nothing about it, how can it not be irrelevant?”

Again, your condition - that we can know nothing about it - leaves room for discussion, but if that were true... then we may as well consider it irrelevant, whether it is or not.
