Harold Joachim & the Jigsaw of Lies
The first credited with the definitive formulation of The Coherence Theory of Truth was Harold Joachim
Now, my view on the coherence theory itself is, let's say, crude for I confess to be ignorant of better versions of it. The basic assertion seems to be that the truth of propositions depends completely on how well it fits with other propositions. For instance, in favor of the theory, the truth of the claim, "god doesn't exist" fits quite well with the proposition, "there's too much evil in the world".
However, in my humble opinion, a web of lies can also be made to cohere. A person can make a false claim and his accomplices can make other claims that altogether form a coherent but false set of claims. I believe many criminal activities, all of which involve creating, sustaining and perpetuating deception, actually employ coherence as a weapon to fool the gullible.
This problem, if it is one, may actually penetrate into the most cherished and apparently satisfactorily proven belief systems; even science may not be immune to this malady. I can't come up with an example off the top of my head but what about the luminiferous ether theory? It coheres quite well with light being a wave and thus requiring some kind of medium. I know present scientific consensus is that the ether doesn't exist but all I want to convey is that had we relied on coherence alone, it would be quite difficult to make sense of wave without a medium.
Relying on only the coherence theory of truth is like believing that just because the pieces of a jigsaw puzzle fits together we have solved the puzzle, arrived at a true picture of reality. This is an error because what we've assembled on just the basis of a fit between the pieces could be perfectly coherent and still completely false.

But the beauty of it is that you could never tell that it was 'false'.
Instead one has to rely on a more pragmatic test.. ie does it work? or at least does it work for you?
And the theory allows that given further evidence, I might have to concede that after all, Trump can tie his shoelaces and therefore I must stop thinking he is an idiot and upgrade him too imbecile.
And as a general rule, it seems fairly reasonable as far as it goes. Miracles are incoherent; don't believe in them.
I don't exactly know the why of bringing up Godel; but, suppose we have a theory that is such and such, it seems to me that as long as the theory is incomplete; whilst remaining coherent, then there's pragmatically no problem, is there?
Or... setting deliberately misrepresenting one's own thought and belief(lies) aside... A web of falsehoods can be quite coherent.
Standards are linguistic devices... I think?
If so, then true belief would require language. Clearly, that's not the case. There are non linguistic creatures who have true belief.
How much of a problem is this, if I understood correctly, regression of definitions? It doesn't seem to be an issue in ordinary discourse. Perhaps language, as we know it, fails to meet the standards of more formal discourse, like in philosophy?

I don't think being unable to discover falsehood is in any way a "beauty" but that's just me. Other theories on truth like the pragmatic theory are not being discussed here; then again, according to coherence theory, other theories of truth must cohere with it. Can you give me the lowdown on the pragmatic theory of truth if that's what you're alluding to?

Firstly, sorry to know Trump isn't in your good books. Secondly, what is the difference, if any, between logical consistency and coherence?

I'm unsure of how Godel's work impacts this discussion but isn't his incompleteness theorems restricted to mathematics? Although I remember him being labeled foremost as a logician. Also, I don't wish to discuss other theories of truth like pragmatism unless you can show me that some proposition concerning them is logically implied by any claims I've made. Thank you.

Does any of what you said have a truth value or are you using some criterion of truth in your claims? If no then what you said is not true but if yes then what criterion of truth did you use?

Ok.
The 'lowdown' on the beautiful theory can be found in my book 'The pattern paradigm', but you won't like it. lol.
IMO truth is best viewed as a label for an idea, perhaps expressed as a statement or proposition, that one believes to be an accurate representation of the world.
PS I label the above as 'true'.
Yes people have believed and indeed still do believe things that other people think are not true. And even people have believed things to be true and later decided that they are not true.
There is no logical inconsistency in this.
I am not sure what you mean by 'psychological state' or are you just trying to distance the concept of 'truth' about the world from human judgement? An impossible and futile task in my opinion.
Well , the word 'truth' would seem to have 2 uses:
1. If a person considers something to be 'true', then they would have no need to investigate the data relating to it any more and can simply use that 'truth' if and when circumstances merit it.
2. If a person communicates that they consider something to be 'true', there is an implied invitation or encouragement for the receiver of the communication to believe it too.
I am not sure what you mean by 'verifiable performative function'.
Of course 'similarly situated observers' cannot be compelled to 'assent'.
You seem to be assuming that all people must see the world in the same way that you do. This is unjustifiable. While there may be considerable consensus about the way the world appears to be, this cannot be justifiably extrapolated to the claim that everyone always sees the world the same way. All you know is the way you see the world.
As for your example, this might well fall into the consensus category; but your conclusion cannot be logically proven, at least not without the inclusion somewhere of a human judgement, which necessarily makes the conclusion subjective and not proven.
I have no idea, I don't follow baseball.
What is your point?
Are you trying to claim that consensus equals undeniable certainty?
:rofl: I'm all over the place.
Well enjoy! :)
Thank you.
What works for you? I'm curious, that's all. You claimed that the notions, if they are different, of true and truth are meaningless. Is this claim true/false and by what criterion/standard?
I guess you are saying some religions might be a well devised set of fallacies phrased in such a way to be coherent? Due to site guide lines I can't name the Holy book but there are atleast one very long book in a particular Holy book that is written in such a way that would make me think this is not written by a crazy man just venting his anger.
No wrong answer, if you feel inclined i can privately send you the name of that book in that Holy book. I'm sure you have better things to do though.
But yes Lawyers do this all the time. You can take 10 coherently written fallacies and present a pretty good argument that can manipulate others to benefit you or I or that guy over there.
Well that is a moot question. First, all communications can be considered to be 'opinions. albeit some are more justified than others. The only way to evaluate communications as to their veracity is to determine whether they are a smooth addition to one's model of the world and the degree to which one trusts the originator of the communication.
There is no simple and foolproof method.
If truth is not a matter of belief/consideration how do you distinguish it from opinion or a lie?
Are any beliefs free of criteria?
:ok:
Are you in any way claiming the truth of what you say? If you are then, following your guidelines, I'd like you to tell me with reference to what are they true?
So now there's a quality called true and truth. I thought you said they were meaningless?
But you haven't pulled even one oar :smile: and that's on your boat, not mine.
I don't get your analogy of sums of integers.
Anyway, it seems that your claims are utilizing a theory of truth. The only theories of truth that I'm familiar with are:
1. The correspondence theory of truth
2. The pragmatic theory of truth
3. The coherence theory of truth
Are you saying all of the above are flawed and if so by which theory of truth did you come to that conclusion?
I have a preference for the correpondence theory of truth which to my understanding asserts truth to be a relationship between propositions and reality - what is spoken/written must, to the best of our ability, reflect what is actually going on in reality.
Are your comments meant to be a reflection of my reality? Does what you say cohere with some other truth that has become apparent to you? Are you being pragmatic whatever that means? Perhaps you're being all of them at the same time? Whatever the case, you've not been upfront about it. Could it be that I'm asking the wrong questions or perhaps you're unable to answer the question not necessarily because you're ignorant but because the matter is too complex for even the best among us.
Thanks. I think I'll follow your advice and read a bit more.
