I think that in some senses truth is associated with action in the world. That’s how we test our hypotheses. Not just in science, in terms of empirical adequacy, but even as children and adults. We learn from experience of doing, not just rote, and we associate effectiveness with truth. That’s not a perfect heuristic, but it’s better than just floating in a sea of propositions as current LLMs largely are.

I agree.

There's a truth of what happened, which as individuals we can only ever know to a limited scope... And then there is truth as a prediction ability (formula of gravity predicts how things fall).

Science is a way to build a shared truth, but as an individual we just need to experience an environment.

One way I've heard it broken down is between functional truths and absolute truths. So maybe we can attain functional truths and transfer those to LLMs through language, but absolute truth can never be attained only approached. (The only absolute truth is the universe itself, and anything else is just an approximation)
