This seems to make the LNC, e.g., contingent on the way the world is. But don't we want something much stricter than that, some way we can talk about necessity and impossibility? Can we arrive at what you're calling "a necessary understanding of the world"?
I'll bring in Nagel any post now! :smile: — J
Yes, and thanks for the summary. Is it clear to you that either Hume or Kant has the better explanation here? Are Jha et al. Kantians? (Note, too, that Kant did not think math was analytic, like logic. He thought it gave us synthetic knowledge about the intuitive concept of "magnitude" -- that is, number per se. This makes me wonder if he would allow math an explanatory role, as in the above discussion.) — J
...mostly shows how poorly folk hereabouts deal with logic. — Banno
ules without interpretation (possibly the natural logic?) used to make the content work (become sound/make sensible). And thus something else is going on that isn't just the formal logic (natural logic that is)...
Also, being a bit of a devil's advocate from my past positions (contra evolutionary psychology), there is no way our species evolved "to use formal logic", rather we have rationalization capacities that happened to be able to form formal logic. It is this rationalization capacity that I am interested in- empirically understood through various methods of anthropologists, evolutionary biologists, cognitive scientists, and the like (possibly).. I'll take even armchair theories as stand-ins for now, but that is the foundation I mean. — schopenhauer1
Check out Søren Brier's academic homepage (and I was alerted to him by Apokrisis) - titles like 'Information and consciousness: A critique of the mechanistic concept of information', 'Bateson and Peirce on the pattern that connects and the sacred'. I also found a paper by Marcello Barbieri on the history of biosemiosis and it's very wide-ranging. — Wayfarer
:up:On the whole, I think physicalism is on the wane. It's real heyday was actually the late 19th century, I think the scientific justification for it was demolished by the introduction of quantum physics in 1927. — Wayfarer
If you like. "Natural logic" will collapse into "formal logic" as soon as you take it seriously. The "rationalisations we make" are the very subject of formal logic. — Banno
I would contend that we have still not left intellection behind. Why? Because an inferential move or rule involves intellection. The manner in which we move from premises to conclusions is not endlessly discursive, or not entirely related to ratiocination. We must understand that the inference is valid in order to undertake it, and this understanding is part of intellection. Logic of course tends to calcify or standardize rules of inference, thus forgetting the importance of understanding them. Basically, the closer we move to that "binding" between the formal logical system and reality, the more immersed we are in intellection, and this includes an understanding of inference. — Leontiskos
That's kinda the point of logical pluralism. — Banno
Yes, and if you "define down" sensing so that it becomes something a thermostat can do, then you're still minus a theory of consciousness, which now has to be defined as something else. — J
Sure, if you like. Whether the binding between reality and logic is metalogical is largely dependent on how you conceive of logic. — Leontiskos
On my view something with no relation to reality (and therefore knowledge) is not logic. Ergo: something without that binding is not logic. It is just the symbol manipulation that Banno mistakes for logic. More precisely, it is metamathematics. — Leontiskos
When you want to call the binding metalogical that makes me think that you take logic to be something that is not necessarily bound to reality in any way at all. What I would grant is that it is a somehow different part of logic, but I do not think that these parts are as easily distinguishable as the modern mind supposes. — Leontiskos
Suppose you know nothing about consciousness, but you examine a human organism and find that there are sensors and nerves. Do you then ask yourself what this is good for? The answer will be that it must have a function. Perhaps you then think that it is there so that these beings can sense what they are doing. So that they are not eaten in the next moment. Sensing is nothing other than consciousness. In our case, this has now become more differentiated, so that we experience entire dramas. This does not change the principle. — Wolfgang
And then a "strong monism," would presuppose a "one true formal system?" But that doesn't seem particularly plausible either. — Count Timothy von Icarus
I've learned a lot about biosemiotics from Apokrisis (including that it exists!) and benefitted a lot from it, although I don't agree with his metaphysics. Biosemiotics on the whole is not materialist in orientation so I don’t see biosemiotics as ‘scientistic’ in the sense that Dawkins/Dennett neo-darwinist materialism is. (Notice, though, that even though C S Peirce is categorised as an idealist philosopher in most directories, Apokrisis will generally downplay his idealist side.) — Wayfarer
Eh. If you take it to mean axiomatic, then it has nothing to do with a good place to start. If you take it to mean a good place to start, then it is not axiomatic. Axioms are not good places to start except in a purely formal or economical sense. This chimera is understandable, given that my use of "foundational" was nothing like "axiomatic." Quite the opposite.
Again, the PNC is a more universal foundation or first principle than modus ponens. It is a foundation in the same sense that the first few feet of the trunk of a Redwood is a foundation. It is stable in a way that the upper branches are not, and folks never directly contravene the PNC. They only do so indirectly when they have climbed out onto limbs and lost track of where they are. — Leontiskos
The closer you get to the foundation, the surer it becomes. For example, modus ponens is arguably the most basic inference or law of propositional logic, and I don't see that it fails. — Leontiskos
laws of logic — Leontiskos
Well, at the very least it is a useful aid for error-checking, even if it is not infallible. It represents a form of calcified analysis that is useful but limited. And it is useful for conceptualizing extended arguments that are difficult to capture succinctly. There are probably other uses as well. — Leontiskos
There are probably other uses as well. I have fought lots of battles against the folks in these parts who have a tendency to make formal logic an unimpeachable god, so I agree with the sort of objection you are considering. — Leontiskos
The OP is a fun way of exploiting this bug, among other things. I don't think it is meant to be more than that. — Leontiskos
I would give Banno the credit of levity here, not snark. It is a philosophical joke, aptly placed in the lounge. The justified decision to not pray turns out to prove God's existence, given a logical translation that is initially plausible. Hanover is reading all sorts of strange things into the OP. — Leontiskos
I'd say the main point of the OP was snark, hitting back at those ancient proofs for the existence of God that can't seem to go away. It points out that attempts to bootstrap something from from logic alone lead to — Hanover
If you treat the premises as contingent statements that have a truth value of their own based upon empirical information or whatever you use to decide if a statement about the world is valid, then you end up with non-sequitur issues, but those non-sequiter issues are not deductive logic fallacies, but are inductive ones. — Hanover
Well, I suppose that’s what my first post above does. The (valid) formal logic is an improper translation of the English language sentence. — Michael
The argument in Banno’s post is a link to a logic tree diagram that shows you why it’s valid. — Michael
Methodological naturalism says behave as if it were and get on with it. Physicalism seems like a vacuous piece of extra metaphysical naturalist baggage in that context. — Baden
Where methodological naturalism needs to be made explicit is when it appears in the guise of a metaphysic - which happens most often in the attempt to subject philosophical problems to scientific scrutiny. To scientism, in other words. That's when it becomes metaphysical, as distinct from methodological, naturalism. — Wayfarer
But when language enters the picture, we get a series of explanations that all involve the sun doing things like rising and falling. While this is accurate pattern recognition, it happens to be untrue. So . . . what is it that allows language to move beyond mere phenomena, and strive for a truth that is observer-independent? — J
He is moving from primitive inferencing- something that is universal and even tribal cultures utilize, to Logic (capital "L") as conventionalized by Greek/Western contingent historical circumstances. Inferencing + cultural contingencies of the Greek city-states + further contingencies of history led to our current conventions of logic. So it is a mix of taking an already universal trait and then exposing it to the contingencies of civilizations that mined it thoroughly and saw use for it.
However, that's not all. ONCE these contingently ratchted inferencing techniques were applied to natural phenomena, we found not only that the conventions worked internally in its own language-game, but that it did something more than mere usefulness to human survival/language-game-following. It actually mapped out predictions and concepts in the world that worked. New techniques now harnessed natural forces and patterns to technological use, far beyond what came before. Math-based empirical knowledge "found" something "about the world" that was cashed out in technology and accurate predictive models. This is then something else- not just conventionalized language games. This particular language-game did something different than other language games.

Don’t want to go there. I was just trying to think of some ‘edge cases’ where there might be actual metaphysical considerations. — Wayfarer

His version is idiosyncratic though. — Count Timothy von Icarus
Semiotics, through Aquinas, John Poinsot, C.S. Perice, and John Deeley is one particularly developed area that has a lot of overlap with this question (Sausser-inspired and post-modern semiotics largely considers the question unanswerable/meaningless and so ignores it though). — Count Timothy von Icarus
