Also it is ironic that with the "Hitler doctrine" a super power doesn't necessarily win all or even most of the wars they fight. A super power just keep enough countries that "might" go to war or engage in aggressive behavior to think twice about doing it and/or not do as much of it as if they they were unopposed. The tactic is basically to keep any country or Axis of countries from getting too big for us to handle and the hope is by stalling them while trying to get bigger, it will buy us enough time for us to do something before they get to bigger -sort of like in WWII we were able to ramp up military manufacturing before Japan and Germany could become too much of a threat. — dclements

I know that I have the subjective experience of colours. I believe that you also have the subjective experience of colours.
I can never know that you have, and I can never demonstrate that you have, but for me, the possibility that you have a subjective experience of colours has both a truth value and meaning.
The truth value is that the proposition "T Clark has the subjective experience of colours" is either true or false. — RussellA
I understand that, but my point is that you cannot make any progress in answering the question if you are not clear on the criteria that the answer should satisfy. Without that the question is effectively meaningless (as you like to say). — SophistiCat
Meaningless for you, because of the particular epistemic criteria that you set out for yourself in this case: if you can't put a proposition to an empirical test, then it is meaningless. (Not so for others, so they must be applying different criteria.) — SophistiCat
Now, in the OP you want to turn the question onto that epistemic criterion itself. But that's clearly inapt: an epistemic criterion is not the sort of thing that you can test by the methods of science. — SophistiCat
It doesn't matter anyway because either is imaginable as a possibility, but both would seem to be impossible to confirm or dis-confirm. — Janus
...pointing out that whether one assigns true or false to this sentence, it must be undecided, and hence it is a candidate for an example fo the sort of sentence you asked for. — Banno
But that makes no sense. — Banno
Seems to me we can assign "true" or "false" to the above sentence without contradiction, so the answer is "yes, there can be sentences that are true or false but undecidable". — Banno
Sometimes ya gotta do what ya gotta do. And no bluff. If I'm president, I share with the Chinese that if they invade Taiwan, then we're all in. And naturally there are lots of reason not to fight that can be appealed to.
Maybe more interesting is what happens if the Russians try to annex the rest of Ukraine. — tim wood
You could consider that a disputable meta-metaphysical claim. I would be quite happy to defend it. — apokrisis
Can human things be described by having a cause that is neither nature nor nurture? If so, what? — TiredThinker
A small point of jargon. But important where folk are mostly arguing rhetorically.
— apokrisis
I'm not sure "rhetoric" is the right word. They're not just trying to convince you of their position, they actually believe in the truth of what they say and are trying to present their position.
Anyway, the difference can be summed up that by saying the principle of bivalence is the logical claim that propositions are to be judged either true or false - true or not true. And a dialectical or dichotomous logic says that any "bivalent" division of metaphysical possibility has to obey the rule of being "mutually exclusive/jointly exhaustive". So to be "true", each has to stand as the logical negatation the other. Or to be more accurate, each has to be the formal inverse of reciprocal of the other.

Reductionism is fine too. It works really well if you want to build machinery or even mechanise human society and the human mind. Simple cause and effect thinking is neat little everyday tool of thought. — apokrisis
What do you think metaphysics ought to deliver as its social good? Does it have a purpose? I can't see any other reason to "do metaphysics" except to attempt to deduce the truth of reality from first principles ... and so set yourself up with clear hypotheses worth the effort of empirical test. — apokrisis

It is the same problem that goes back to Kant's phenomenon and noumenon. Kant proposed that a phenomenon is a perceptive representation of an object existing in the mind of a perceiver, rather than the object in itself, the noumenon. Kant did not argue that the world of the noumenon does not exist, for there to be an appearance, there must be something for there to be an appearance of. It is just that human knowledge of the true nature of the noumenon is impossible, as the true nature of the noumenon is always mediated by the senses. In that, for example, we perceive the colour red, we don't perceive a wavelength of 700nm. — RussellA

I believe a large part of philosophy is figuring out what we should spend our efforts on pursuing in reality. — Philosophim
Technically I would say "It may be true or false, but it is extremely likely that it is unknowable." It may just happen that the first planet you look at contains the penny. Extremely unlikely, but not implausible. But that is the way I see truth and falsity. They are independent of our knowledge. — Philosophim
We have the concept multiverse, but if we can never know even in principle whether multiverses exist or not, our concept of multiverse must remain fictional, as a unicorn or Conan Doyle. — RussellA

I guess your point is truth is not the only game in town. — TheMadFool
But history has shown that dialectical and trialectic reasoning - a move towards holism - actually deliver the better results when it comes to the forming of general intuitions. Reductionist predicate logic is what you use more in the next step of forming deductive statements that are then suitable for a process of inductive confirmation, or the experimental test of a bivalently-framed prediction. — apokrisis
So one thing that is clear to any logical holist is that yes/no thinking lacks sufficient sophistication. You need further categories - a third option as an answer, such as yes, no, or vague. — apokrisis
Pragmatism builds that answer in. The theory makes some kind of reductively bivalent claim about reality. It is a good thing to be clear in this way. But then the theory is only ever deemed verified or falsified provisionally. The evidence might lean heavily on way or the other. But always, the fact is that there remains something ambiguous or indeterminate about its truth status. — apokrisis
Then when it comes to quantum theory, we find ourselves bumping up against the fact that nature itself must have this same kind of logical holism. The vagueness that we need to include in our epistemic methodology becomes also a useful third category when we speak of nature “in itself”. — apokrisis

I’m saying that the term ‘metaphysics’ has a scope, defined originally against Aristotle, developed by the subsequent tradition. Tao Te Ching falls outside the scope. As does Vedanta and Buddhism. Which is not to say that those texts and traditions don’t deal with some of the same subjects, but they do so in very different terms, different languages and different cultural tropes. When you try and combine them all into some grand meta-subject called ‘metaphysics’ then you loose a great deal of specificity which is why you can’t find any criteria for deciding their truth or falsehood. — Wayfarer
Ok, I'll leave off that - seems the thread is headed off into pragmatics anyway. Let me know what you decide about the undecidable sentence in my first post. — Banno
