You think there are objective moral facts. Are they logical facts, like mathematical truths? Or are they physical facts, contingent on physical law and our actual universe, out there to be discovered?
So you admit that there are two different kinds of objective facts. Given that there are two different kinds, why can’t there be more?
These are two quite different things. We group them under one name, ‘facts’, but that is just a convention. That’s why I wanted to find out which kind we were talking about.
Saying that “there might be a third kind” is misleading: it is a matter of definitions of words. You propose there might be some undiscoverd X. You also propose that if we discovered X, we would be willing to call it “a new kind of fact”. But X itself is vastly more interesting than what words we might use.
Therefore please taboo “fact” and tell me, what is it you think there may be more of?
Certainly, they have a lot in common, as well as a lot of differences.
But this discussion doesn’t seem profitable. We shouldn’t be discussing the probability that “another kind of fact” exists. Either someone has a suggestion for a new kind of fact, which we can then evaluate, or else the subject is barren. The mere fact that “we’ve not ruled out that there might exist more things we would choose to apply the word ‘fact’ to” is very weak evidence. We’ve not ruled out china teacups in solar orbit, either, but we don’t spend time discussing them.

So if I understand your meta-theory correctly, anyone living before the scientific method, or simple hasn’t heard of it, should be a Cartesian skeptic.
I’m sorry, I don’t understand what you mean. By “Cartesian skeptic” do you mean a Cartesian dualist who is skeptical of pure materialism? Or a Cartesian skeptic who does not wish to rely on his senses, who is skeptical of scientific inquiry into objective reality? Or something else?
That’s not physical anti-realism, but it’s a sort of skepticism about physical realism. However, nothing can “prove” physical realism correct if you don’t already accept it.
If someone doesn’t believe his sense inputs reflect something with independent existence, then any new information they receive via those very same sense inputs can’t logically influence their belief. Learning about the scientific method would not matter. Living today or at Descartes’ time or ten thousand years ago, there are still exactly the same reasons for being a physical realist: the world just seems that way, we act that way even if we proclaim we don’t believe in it, we can’t change or escape the world we perceive via our senses by wishing it, and we have a strong instinct not to die.
Interesting point. But that’s very weak evidence (because as I said the two known instances have significant differences). Also, this is a heuristic and produces many false positives.
At best it motivates me to remain open to arguments that there might be more kinds of ‘truth’, which I am. But the mere argument that there might be is not interesting, unless someone can provide an argument for a concrete example. Or even a suggestion of what a concrete example might be like.

You should study more history of ideas; once you see several examples of seemingly-unsolvable philosophical problems that were later solved by intellectual paradigm shifts, you become much less willing to believe that a particular problem is unsolvable simple because we currently don’t have any idea how to solve it.
I don’t believe a problem is unsolvable. I don’t see a problem in the first place. I don’t have any unsolved questions in my world model.
You keep saying I should be more open to new ideas and unsure of my existing ideas. But you do not suggest any concrete new idea. You also do not point to the need for a new idea, such as an unsolved problem. You’re not saying anything that isn’t fully general and applicable to all of everyone’s beliefs.
I’m not interested in dialogue with physical anti-realists. Certain mutual assumptions are necessary to hold a meaningful conversation, and some kind of physical realism is one of them. Another example is the Past Hypothesis: we must assume the past had lower entropy, otherwise we would believe that we are Boltzmann brains and be unable to trust our memories or senses. A third example is induction: believing the universe is more likely to be lawful than not, that our past experience is at least in principle a guide to the future.
If moral realists are on the same level as physical realists—if they have no meaningful arguments for their position based on shared assumptions, but rather say “we are moral realists first and everything else follows, and if it conflicts with any other epistemological principles so much the worse for them”—then I’m not interested in talking to them (about moral realism). And I expect a very large proportion of people who agree with LW norms on rational thinking would say the same.

There’s a reason we use the same word for both of them. They have a lot in common, for example being extremely objective in practice.

Someone who doesn’t believe his sense inputs necessarily reflect any reality.

There could be more. It just turns out that there aren’t.
Do you have any evidence for this besides not being able to think of a third meta-theory?
Do you have any evidence against it? Are you able to think of a third?

The physical anti-realist doesn’t see any problem in his world view either.
