  The test to know if anything is an absolute truth is if it is called an absolute truth. If it is called an absolute truth, then it isn’t an absolute truth. If it isn’t called an absolute truth, then it isn’t an absolute truth. Absolute truths don’t exist. If someone tells you something is an absolute truth, stop listening to them.

  They’re made up constructs that reflect the absolute truth when applied correctly (from his perspective).

  Well, it depends on your definition of truth and it could be the absolute truth by definition. A theorem is absolutely true in the same way that “a bachelor is an unmarried man” is categorically true.

    “This line on the map is perpendicular to this other line on the map” is not a statement about the territory.

  I was about to say “incompleteness theorem”!

    That just means we can’t know everything about the system. Not that it is not true.

    That’s computer science alongside with Church/Turing. Maths could have tried to claim it but they doubled down on formalism so they don’t deserve it.

    That said though incompleteness follows from nothing but logical implication itself so it’s more fundamental than physics (try to imagine a physics without cause and effect) and philosophy (find me a philosopher who wasn’t asleep during their logic lectures).

      Yeah, I meant to say that the incompleteness theorem proves that math cannot be perfectly pure and fundamental. I don’t exactly care which field claims it, because I don’t like to encourage artificial boundaries between disciplines. It’s nice to use information theory results in physics :)

        The other way around: As long as you accept that cause and effect are a thing, you must accept that there are things that are, fundamentally, uncomputable. And as our universe very much does seem to have cause and effect that’s a physical law, likewise is complexity theory. Differently put: God can’t sort a list with fewer than O(n log n) comparisons.

  Math ain’t made up. Math is discovered.

    I don’t think that’s a settled debate IIRC
