I supose the thread is lon enough to forgive your not having read the back story. Science can tell us how things are. So it can tell us what we can do...

, Perhaps you might enjoy Logic and Consciousness. A bit about thought and logic, and some considerations on Frege and Penrose. It's not a long read. ...

Let's take such an account seriously. How will you tell if you have your ethical theory right? After all, it will not do to go to all that effort and ...

So do I. That's one of the reasons I use it. It's mere propaganda, and should leave folk feeling cold.

Why not? Moore, at least, says that they are. And saying that they are not is presenting a particualr moral theory. Argue your case! I quite agree! An...

OK.

Is that much different to or or to ? Looks as if we have broad agreement. Always cause for concern. We have that if you pray then your prayers will be...

~~ Again. How are theories of morality to be judged unless on the basis of the actions they justify? Unless you are claiming that the only criteria fo...

Then presumably you conclude that paraconsistent logic is not logic proper? And isn’t the liar in ordinary language? All this simply to show what the ...

OK.

Paraconsistent logic includes the study of logics with other than two truth values. Such logics might include those that are valid yet inconsistent, o...

You've suggested a third truth-value - neither true nor false. Is that right?

So it's para-consistent?

And of course, if we have differing stipulations, the One True Stipulation will be correct.

It's about what "Logical Monism" is about. :wink:

You keep claiming monism to be the "dominant" position. I see no evidence of that. Indeed, any logician will be aware that there are various logical s...

Rights are not found in the world. They are given, by us. If @"Bob Ross" would have the argument framed in terms of rights, then we can evaluate it is...

That's on the mark. appears to think this amounts to nihilism. It doesn't. Nihilism would have it that there are no laws of logic, that logic is at be...

That little parenthetical withdrawal made me smile. You rights are ABSOLUTE, except for...

~~ Pretty much. That's right. When your moral theory arrives at an immoral position, then your moral theory is wrong. Giving a zygote standing over Mr...

Yesterday there was much joy on Fox as Trump flipped burgers and drained the oil from chips at a Maccas. Today I read there is an outbreak of food poi...

:up:

@"fdrake" shared some material with me on Relevant Logic, which is directly applicable here. There is a gap in relvance between the existence of god a...

I'm not at all keen on so-called "trolly" arguments. There are intractable moral situations.

The ACT - the capital territory of Australia - had it's local election last week. We use Hare-Clark voting. This works by assigning a quota, calculate...

Your question is illicit. The standing of Mrs Smith ought far surpass whatever standing you might grant the blastocyst. Your attempts to show otherwis...

@"Leontiskos", as this thread draws to a close, has still not addressed, and apparently is yet to read, the article from which this topic derives, nor...

so as I understand it it has much the same power as first order logic. Not a failing, quite curious actually. But difficult to work with.

I've been unable to find a substantive account of the L?G?S Hypothesis. It's not apparent how it might deal with paraconsistent or non-binary logics, ...

I'd thought of Meno's "paradox" as a precursor to bits of Wittgenstein- that there are ways of understanding (knowing) that are not the result of rati...

I think Lambda Calculus had this feel to it originally. It's reputedly the simplest language in which anything computable can be... computed.

Yep. Excellent post.

:smile: Well, made me laugh out loud. People create knowledge. I'm not following what his claims are here. Is he suggesting that we remember logic fro...

Missed this: The argument is pretty clear, and has been stated a few times. Whatever standing the cyst has is negligible in comparison to that had by ...

So you call a logic "correct" when I might call it "applicable". And Paraconsistent logic is for you "correct" when used for processing images and sig...

I edited my last post to make the meaning clearer. My apologies.

Fine by me. But if your logic teacher set parsing "If there is no god then your prayers will not be answered" into prop form, what would be the better...

Except that the double effect was part of an extended discussion of abortion involving Philippa Foot and Anscombe, the very one in which what 'mercans...

I think so. So if there is a god then my prays will be answered. If there is no god, they will not be answered. But how to pars this in propositional ...

If their position is that the general laws are those which hold in "correct logics" and that "correct logics" are those that use general laws... they ...

If there are general laws... That's the issue. How so?

Perhaps it was a stylistic decision, in order to keep more options open for the monist. I don't know. I don't see much hanging off it. The monist says...

A law of aviation would presumably apply to all flight, and a law of logic to all logics.

Well, even "necessary" has differing interpretations depending on which logical system one chooses - S1 through S5 for a start. And we have logical sy...

The idea of a correct logic is endemic to logical monism. I'm not sympathetic to monism, and so I'm not the one to ask this question of. But presumabl...

Well, there are consistent and useful systems of logic.

Well, I've been trying to work out what you are claiming, on the presumption that you are advocating monism. So again, a monist holds that there are l...

Perhaps. Although a logician's presenting a logic would be their making use of it. In all logical systems, presumably. But I would be happy to conside...

Come on. When it has a use. From the core article: 1) To be a law of logic, a principle must hold in complete generality. 2) No principles hold in com...
