"It would be very uncomfortable to have discussions that on the surface appear to be about the nature of reality, but which really are about something else, where the precise value of 'something else' is unknown to me."
Indeed. I agree, although I find it extremely uncomfortable even when the something else is known to me.
For example, once I had a discussion with someone which seemed to be going pretty well, and which fully appeared to be about the nature of reality, and which we were both enjoying. Then at one point in the discussion I said something like "you know, the reason I thought X was true was because of Y", where X and Y had some reference to another discussion that we had once held and in which we had disagreed.
The person responded, "now you're ruining everything!!"
Why was I "ruining everything"? The reason is that I misunderstood the point of the discussion. I thought it was about the nature of reality. But, in fact, they simply intended it as a discussion about the relationship between the two of us, and they understood my reference to a discussion in which we disagreed as something harmful to the relationship.
In the end I have c...
The blue apple test: Speak out the sentence "I'm a blue apple". See how it feels. It likely makes you laugh because it's absurd. That's how beliefs that feel absurd feel like.
If you have that reference feeling you can speak a sentence like "I'm not worthy of success" and see how that sentence feels like. If it feels more true, than you believe it on some level even if as an rationalist you would never ever say that you believe "I'm not worthy of success".
If the beliefs that actually drive your actions are radically different than the beliefs towards which you admit to when thinking intellectually about them, you are likely going to be plagued by akrasia.
On LW we have the alief/belief distinction. We might say that you don't believe "I'm not worthy of success" when it fails the blue apple test but you just alieve it. Most people don't distinguish the two and only deal in aliefs.
Having a conversation where you actually express your alives and express them can be interesting.
I went down the rabbit hole of researching the question "what is truth?" soon after I joined LW almost 3 years ago, and ended up with a rather unpopular anti-Platonic ontology of the term "truth" being worse than useless in most cases. The correspondence theory of truth stopped making sense to me because there is nothing for it to correspond to. So, it's somewhat more radical than William James's pragmatic theory of truth. But I guess this is probably not what you are interested in.
As for your options, have you considered the possibility that 99% of people have never formulated a coherent philosophical view on the theory of truth?
BBDD: I'm increasingly of the opinion that truth as correspondence to reality is a minority orientation.
PeerGynt: I've spent a lot of energy over the last couple of days trying to come to terms with the implications of this sentence.
Let me give you the basic outlines of what I am thinking. It has been a gusher of explanation and clarity for me.
First consider the basic distinction around here between between epistemic rationality and instrumental rationality.
Epistemic Rationality:
...The art of obtaining beliefs that correspond to reality as closely as
I am mostly a coherentist and get constantly tripped up by the correspondencist attitudes the sequences here take. So it may be a job for me. But beware, I am a sloppy arguer, I suck at being precise and exact, as I think in pictures which may be a good thing but the result is often "sorta-kinda y'know what I mean?" and useless for people who have a mathemethicians precise mind.
A) My main issue with correspondence theory is over-valuing the accuracy of observation, sensory experience etc. There is a hidden assumption that hypothesis-building or t...
I'd say there are three phenomena going on:
There are specific problems with correspondence theory -- what do mathematical truths correspond to? moral truths? modal truths? vague truths? -- which either cause philosophers to reject correspondence theory in more classical domains, or cause them to adopt an ersatz theory where some truths depend on correspondence and some depend on other things. (This is approximately where I am, and arguably makes me a rejector of 'correspondence theory,' though I accept it in the mundane contexts LWers generally mean it.)
I reject the correspondence theory of truth (at least what philosopher's call the "correspondence theory", which I think has certain important differences from the view Eliezer subscribes to).
I started out writing a description of my views in a comment, but it ended up being way too long, so I made it a separate post. Here it is.
On the other hand, I am also basically in agreement with Megan McArdle's point of view. Despite maintaining what I said about people's relationship with reality, I think that particular arguments and positions that people hold usually do have some worth, and that you can always get something out of it if you try. Any discussion will go much better you take what people say and begin with part of it that you agree with -- and you should always be able to find something that you agree with -- rather than jumping immediately to the parts you disagree with. This makes the whole difference between a friendly discussion and an angry argument, and the former is much more productive for everyone than the latter.
I think you need to distinguish between rejecting the correspondence theory (wholly) , and rejecting the correspondence-only approach in favour of something more multifaceted. I'm happily in the latter camp, FYI.
I'm not sure succeeding at number 4 helps you with with the unattractiveness and discomfort of number 3.
Say you do find some alternative steel-manned position on truth that is comfortable and intellectually satisfying. What are the odds that this position will be the same position as that held by "most humans", or that understanding it will help you get along with them ?
Regardless of the concept of truth you arrive at, you're still faced with the challenge of having to interact with people who have not-well-thought-out concepts of truth in a way that is polite, ethical, and (ideally) subtly helpful.
I'd love to hear a more qualified academic philosopher discuss this, but I'll try. It's not that the other theories are intuitively appealing, it's that the correspondence theory of truth has a number of problems, such as the problem of induction.
Let's say the one day we create a complete simulation of a universe where the physics almost completely match ours, except some minor details, such as that some specific types of elementary particles, e.g. neutrinos are never allowed to appear. Suppose that there are scientists in the simulation, and they work out...
The common-sense version of truth is "telling it like it is". The big problem with this notion is that reality makes it hard to properly perceive truth. Figuring out the laws of reality is an arduous task that took thousands of years, required a level of civilization far removed from our ancestral environment, and is still far from complete. Survival means using a number of shortcuts and heuristics to get a good enough approximation. This leads to a pragmatic notion of truth where "correspondence to reality" is a goal insofar as it has ...
Your optimism is heroic. I also don't think we should accept that the rest of humanity are morons, going to hell in a hand-basket. I subscribe to a bit from Cormac McCarthy's No Country For Old Men, "I think the truth is always simple. It has pretty much got to be. It needs to be simple enough for a child to understand. Otherwise it'd be too late. By the time you figured it out it would be too late." I also think the main fundamentals of reality have to be like that. If they weren't we'd just have to despair over our fellow man.
Your understanding...
Statements contain primary, secondary, tertiary, and quatnary meanings and nuances.

There's a simple example of a case where the secondary meaning supersedes what I'm temporarily calling the primary meaning. The above statement is incorrect in a primary sense (in truth, they believe they understand perfectly well), and correct in a secondary sense of what they're really trying to convey. The user is operating in the secondary sense when they speak.
But here's the fun part - people usually don't know which sense they ...
A couple of days ago, Buybuydandavis wrote the following on Less Wrong:
I've spent a lot of energy over the last couple of days trying to come to terms with the implications of this sentence. While it certainly corresponds with my own observations about many people, the thought that most humans simply reject correspondence to reality as the criterion for truth seems almost too outrageous to take seriously. If upon further reflection I end up truly believing this, it seems that it would be impossible for me to have a discussion about the nature of reality with the great majority of the human race. In other words, if I truly believed this, I would label most people as being too stupid to have a real discussion with.
However, this reaction seems like an instance of a failure mode described by Megan McArdle:
With this background, it seems important to improve my model of people who reject correspondence as the criterion for truth. The obvious first place to look is in academic philosophy. The primary challenger to correspondence theory is called “coherence theory”. If I understand correctly, coherence theory says that a statement is true iff it is logically consistent with “some specified set of sentences”
Coherence is obviously an important concept, which has valuable uses for example in formal systems. It does not capture my idea of what the word “truth” means, but that is purely a semantics issue. I would be willing to cede the word “truth” to the coherence camp if we agreed on a separate word we could use to mean “correspondence to reality”. However, my intuition is that they wouldn't let us to get away with this. I sense that there are people out there who genuinely object to the very idea of discussing whether a sentences correspond to reality.
So it seems I have a couple of options:
1. I can look for empirical evidence that buybuydandavis is wrong, ie that most people accept correspondence to reality as the criterion for truth
2. I can try to convince people to use some other word for correspondence to reality, so they have the necessary semantic machinery to have a real discussion about what reality is like
3. I can accept that most people are unable to have a discussion about the nature of reality
4. I can attempt to steelman the position that truth is something other than correspondence
Option 1 appears unlikely to be true. Option 2 seems unlikely to work. Option 3 seems very unattractive, because it would be very uncomfortable to have discussions that on the surface appear to be about the nature of reality, but which really are about something else, where the precise value of "something else" is unknown to me.
I would therefore be very interested in a steelman of non-correspondence concepts of truth. I think it would be important not only for me, but also for the rationalist community as a group, to get a more accurate model of how non-rationalists think about "truth"
