Not sure I follow? Do you mean: it’s valuable to know that just-plain-truth is always available with sufficient effort?

Yes. Not practically available. It's valuable to know it exists, even if not tractable or reachable.

Ah. I’m not persuaded that it exists, and not persuaded that it would be valuable to know that does, if it did. Do you have in mind particular reasons to think these?

That an objective reality exists I take as fairly self-evident. I could talk about it but it'd get way too long. It's valuable because it allows the idea that some descriptions fit reality better than others, and without that we fall into radical relativism.

I agree that radical relativism is wrong and harmful; I don’t agree with the rationalist program for avoiding it. And, I agree that Twitter is not a good medium for sorting that out!

What would you say the rationalist program is? Based on what you say elsewhere I suspect you have something quite narrow in mind.

Yes that's what I thought. I'm just doubtful that there are many people who consistently believe that. Some might sound like it sometimes, but I wouldn't assume too much from that.
