The field as a whole (or rather, some within it, to be more accurate) takes these issues seriously as a matter of debate, yes, but arguing over controversial claims is the entire point of philosophy so that's no mark against it. It's also a radically different position from the strong claim you've advanced here that the field itself is broken, which is nonsense to anyone familiar with modern moral philosophy and ethics/meta-ethics and is dangerously close to a strawman argument.

To say the problem is "rampant" is to admit to a limited knowledge of the field and the debates within it.

Well, Lukeprog certainly doesn't have a limited knowledge of philosophy. Maybe you can somehow show that the problem isn't rampant.

How do you decide whether a claim is controversial?

Just see if people are arguing over it. Duh.

You have precisely identified the fundamental problem with philosophy.

DDTT. Don't study words as if they had meanings that you could discover by examining your intuitions about how to use them. Don't draw maps without looking out of the window.

Positively, they could always start here.

BS. For example, Eliezer's take on logical positivism in the most recent Sequence is interesting. But logical positivism has substantial difficulties - identified by competing philosophical schools - that Eliezer has only partially resolved.

Aristotle tried to say insightful things merely by examining etymology, but the best of modern philosophy has learned better.

I only see objections to traditional strains of positivism. It doesn't seem they even apply to what EY's been doing. In particular, the problems in objections 1, 3C1, 3C2, and 3F2 have been avoided by being more careful about what is not said. Meanwhile, 2 and 3F1 seem incoherent to me.

3C1: The correspondence relation must be some sort of resemblance relation. But truthbearers do not resemble anything in the world except other truthbearers—echoing Berkeley's “an idea can be like nothing but an idea”.

I don't see how Eliezer could dodge this objection, or why he would want to. Very colloquially, Eliezer thinks there is an arrow leading to "Snow is white" from the fact that snow is white. Labeling that arrow "causal" does nothing to explain what that arrow is. If you don't explain what the arrow is, how do you know that (1) you've said something rigorous or (2) that the causal arrows are the same thing as what we want to mean by "true"?

Objection 1: Definitions like (1) or (2) are too broad; although they apply to truths from some domains of discourse, e.g., the domain of science, they fail for others, e.g. the domain of morality: there are no moral facts.

As stated, this objection is too strong (because it assumes moral anti-realism is true). The correspondence theory can be agnostic in the dispute between moral realism and moral anti-realism. But moral realists intend to use the word "true" in exactly the same way that scientists use the word. Thus, a correspondence-theory moral realist needs to be able to identify what corresponds to any particular moral truth - otherwise, moral anti-realism is the correct moral epistemology.

Most people are moral realists, so if your theory of truth is inconsistent with moral realism, they will take that as evidence that your theory of truth is not correct.


Look, no one but a total idiot believes Mark's epistemic theory. There is an external world, with sufficient regularity that our physical predictions will be accurate within the limits of our knowledge and computational power. The issue is whether that can be stated more rigorously - and the different specifications are where logical positivists, physical pragmitists, Kunn and other theorists disagree.

I do agree that objections 2 and 3F2 are not particularly compelling (as I understand them).

3C1: The correspondence relation must be some sort of resemblance relation. But truthbearers do not resemble anything in the world except other truthbearers—echoing Berkeley's “an idea can be like nothing but an idea”.

This is actually a very easy one to respond to. Truthbearers do resemble non-truthbearers. What must ultimately be truth-bearing, if anything really is, is some component of the world -- a brain-state, an utterance, or what-have-you. These truth-bearing parts of the world can resemble their referents, in the sense that a relatively simple and systematic transformation on one would yield some of the properties of the other. For instance, a literal map clearly resembles its territory; eliminating most of the territory's properties, and transforming the ones that remain in a principled way, could produce the map. But sentences also resemble the territories they describe, e.g., through temporal and spatial correlation. Even Berkeley's argument clearly fails for this reason; an immaterial idea can systematically share properties with a non-idea, if only temporal ones.

Eliezer thinks there is an arrow leading to "Snow is white" from the fact that snow is white.

Language use is a natural phenomenon. Hence, reference is also a natural phenomenon, and one we should try to explain as part of our project of accounting for the patterns of human behavior. Here, we're trying to understand why humans assert "Snow is white" in the particular patterns they do, and why they assign truth-values to that sentence in the patterns they do. The simplest adequate hypothesis will note that usage of "snow" correlates with brain-states that in turn resemble (heavily transformed) snow, and that "white" correlates with brain-states resembling transformed white light, and that "Snow is white" expresses a relationship between these two phenomena such that white light is reflected off of snow. When normal English language users think white light reflects off of snow, they call the sentence "snow is white" true; and when they think the opposite, they call "snow is white" false. So, there is a physical relationship between the linguistic behavior of this community and the apparent properties of snow.

Most people are moral realists, so if your theory of truth is inconsistent with moral realism, they will take that as evidence that your theory of truth is not correct.

Yes, but is our goal to convince everyone that we're correct, or to be correct? The unpopularity of moral anti-realism counts against the rhetorical persuasiveness of a correspondence theory combined with a conventional scientific world-view. But it will only count against the plausibility of this conjunction if we have reason to think that moral statements are true in the same basic way that statements about the whiteness of snow are true.

one we should try to explain as part of our project of accounting for the patterns of human behavior.

In brief, I disagree that we are trying to explain human behavior. We are trying to develop an agent-universal explanation of truth. The risk of focusing on human behavior (or human brain states) is that the theory of truth won't generalize to non-human agents.

Regarding moral facts, I agree that our goal is true philosophy, not comforting philosophy. I'm a moral anti-realist independent of theory-of-truth considerations. But most people seem to feel that their moral senses are facts (yes, I'm well aware of the irony of appealing to universal intuitions in a post that urges rejection of appeals to universal intuitions).

The widespread nature of belief in values-as-truths cries out for explanation, and the only family of theories I'm aware of that even try to provide such an explanation is wildly controversial and unpopular in the scientific community.

I'm not sure 'agent' is a natural kind. 'Truth' may not be a natural kind either; it may be a very gerrymandered, odd-looking collection of properties. So I spoke in terms of concrete human behaviors in order to maintain agnosticism about how generalizable these properties are. If they do turn out to be generalizable, then great. I don't think any part of my account precludes that possibility.

The widespread nature of belief in values-as-truths cries out for explanation

Yes. My explanation is that our mental models do treat values as though they were real properties of things. Similarly, our mental models treat chairs as discrete solid objects, treat mathematical objects as mind-independent reals, treat animals as having desires and purposes, and treat possibility and necessity as worldly facts. In all of these cases, our evidence for the metaphysical category actually occurring is much weaker than our apparent confidence in the category's reality. So the problem is very general; it seems that most of our beliefs are predicated on useful fictions (analogous to our willingness to affirm the truth of 'Sherlock Holmes is a detective, not a carpenter'), in which case we are committed either to an error theory or to revising our standards for what 'truth' is.

I don't see how Eliezer could dodge this objection, or why he would want to.

I would phrase that as that he has recast it so it is non-objectionable.

A lot of the other objections are of the nature "how do you know?" And generally he lets the answer be, "we don't know that to a degree of certainty that - it has been correctly pointed out - would philosophically objectionable."

Comment author: TimS 29 November 2012 08:42:53PM 0 points [-]

Well, that moves much closer to making objection 2 meaningful. If all that the correspondence theory of truth can do is reassure us that our colloquial usage of "truth" gestures at a unified and meaningful philosophical concept, then it isn't much use. It is not like anyone seriously doubts that "empirically true" is a real thing.

And I say that as a post-modernist.

Comment author: Luke_A_Somers 29 November 2012 10:35:29PM 0 points [-]

I still don't understand this 'usefulness' objection. If the correspondence theory of truth is a justification for colloquial notions of truth, its primary utility does lie in our not worrying too much about things we don't actually need to worry about. There are other uses such as molding the way one approaches knowledge under uncertainty. The lemmas needed to produce the final "everything's basically OK" result provide significant value.

That's a re-invention of LP, which has problems well known to philosophers.

Eliezer has written quite a bit about how to do philosophy well, and I intend to do so in the future.

If you'll pardon the pun, I leave you with "Why I Stopped Worrying About the Definition of Life, and Why You Should as Well".

Comment author: Peterdjones 29 November 2012 10:26:03PM *  1 point [-]

I ha ve read a lot of philosophy, and I don't think EY is doing it at particualrly well. His occasional cross-disciplinary insights keep me going (I'm cross disiplinary too, I started in science and work in I.T). But he often fails to communicate clearly (I still don't know whether he thinks numbers exist) and argues vaguely.

If you'll pardon the pun, I leave you with "Why I Stopped Worrying About the Definition of Life, and Why You Should as Well".

I don't see your point. For one thing, I'm not on the philosohpy "side" in some sense exclusive of being on the science or CS side or whatever. For another. there are always plenty of phils. who are agin GOCFA (Good Old Fashioned Conceptual Analysis). The collective noun for philosophers is "a disagreement". Tha'ts another of my catchphrases.

Agree! Very frustrating. What I had in mind was, for example, his advice about dissolving the question, which is not the same advice you'd get from logical positivists or (most) contemporary naturalists.

I don't see your point.

Sorry, I should have been clearer that I wasn't trying to make much of a point by sending you the Machery article. I just wanted to send you a bit of snark. :)

I don't see the significance of that. You definitely get it from some notable naturalists,

I skimmed the paper. Dennett's project is a dissolving one, though he does less to explain why we think we have qualia than Yudkowsky did with regard to why we think we have free will. But perhaps Dennett wrote something later which more explicitly sets out to explain why we think we have qualia?

Comment author: Sniffnoy 29 November 2012 05:32:31PM *  0 points [-]

Only if the question is meaningful. Of course, just saying "Don't do that then" doesn't tell you how to resolve whether that's the case or not, but necessarily expecting an answer rather than a dissolution is not necessarily correct.

Defund philosophy departments to the benefit of computer science departments?

Comment author: Peterdjones 29 November 2012 04:03:09PM *  -2 points [-]

And the CS departments are going to tell us what the meaning of life is?

If have to give up on even trying to answer the questions, you don't actually have a better alternative.

Comment author: siodine 29 November 2012 04:11:37PM *  0 points [-]

I absolutely loathe the way you phrased that question for a variety of reasons (and I suspect analytic philosophers would as well), so I'm going to replace "meaning of life" with something more sensible like "solve metaethics" or "solve the hard problem of consciousness." In which case, yes. I think computer science is more likely to solve metaethics and other philosophical problems because the field of philosophy isn't founded on a program and incentive structure of continual improvement through feedback from reality. Oh, and computer science works on those kinds of problems (so do other areas of science, though).

Comment author: Peterdjones 29 November 2012 04:19:19PM *  -2 points [-]

I don't think you have phrased "the question" differntly and better, I think you have substituted two differnt questions. Well, maybe you think the MoL is a ragbag of different questions, not one big one. Maybe it is. Maybe it isn't. That would be a philsophical question. I don't see how empiricsm could help. Speaking of which...

What instruments do use to get feedback from reality vis a vis phenomenal consciousness and ethical values? I didn't notice and qualiometers or agathometers last time I was in a lab.

I've substituted problems that philosophy is actually working on (metaethics and conciousness) with one that analytic philosophy isn't (meaning of life). Meaning comes from mind. Either we create our own meaning (absurdism, existentialism, ect) or we get meaning from a greater mind that designed us with a purpose (religion). Very simple. How could computer science or science dissolve this problem? (1) By not working on it because it's unanswerable by the only methods we can have said to have answered something, or (2) making the problem answerable by operationalizing it or by reforming the intent of the question into another, answerable, question.

Through the process of science, we gain enough knowledge to dissolve philosophical questions or make the answer obvious and solved (even though science might not say "the meaning of life is X" but instead show that we evolved, what mind is, and how the universe likely came into being -- in which case you can answer the question yourself without any need for a philosophy department).

If I want to know what's happening in a brain, I have to understand the physical/biological/computational nature of the brain. If I can't do that, then I can't really explain qualia or such. You might say we can't understand qualia through its physical/biological/computational nature. Maybe, but it seems very unlikely, and if we can't understand the brain through science, then we'll have discovered something very surprising and can then move in another direction with good reason.

Unless it is. Maybe the MoL breaks down into many of the other topics studied by philosophers. Maybe philosophy is in the process of reducing it.

Meaning comes from mind. Either we create our own meaning (absurdism, existentialism, ect) or we get meaning from a greater mind that designed us with a purpose (religion). Very simple

No, not simple

How could computer science or science dissolve this problem? (1) By not working on it because it's unanswerable by the only methods we can have said to have answered something,

You say it is "unanswerable" timelessly. How do you know that? It's unanswered up to present. As are a number of scientific questions.

or (2) making the problem answerable by operationalizing it or by reforming the intent of the question into another, answerable, question.

Maybe. But checking that you have correctly identified the intent, and not changed the subject, is just the sort of armchair conceptual analysis philosophers do.

Through the process of science, we gain enough knowledge to dissolve philosophical questions or make the answer obvious and solved

You say that timelsessly, but at the time of writing we have done where we have and we don't where we haven;t.

(even though science might not say "the meaning of life is X" but instead show that we evolved, what mind is, and how the universe likely came into being -- in which case you can answer the question yourself without any need for a philosophy department).

But unless science can relate that back to the initial question , there is no need to consider it answered.

If I want to know what's happening in a brain, I have to understand the physical/biological/computational nature of the brain.

That's necessary, sure. But if it were sufficient, would we have a Hard Problem of Consciousness?

If I can't do that, then I can't really explain qualia or such.

But I am not suggesting that science be shut down, and the funds transferred to philosophy.

You might say we can't understand qualia through its physical/biological/computational nature. Maybe, but it seems very unlikely,

It seems actual to me. We don't have such an understanding at present. I don't know what that means for the future, and I don't how you are computing your confident statement of unlikelihood. One doens't even have to believe in some kind of non-physicalism to think that we might never. The philosopher Colin McGinn argues that we have good reason to believe both that consc. is physical, and that we will never understand it.

and if we can't understand the brain through science,

We can't understand qualia through science now. How long does that have to continue before you give up? What's the harm in allowing philsophy to continue when it is so cheap compared to science?

PS. I would be interested in hearing of a scientific theory of ethics that doens't just ignore the is-ought problem.

Comment author: siodine 29 November 2012 10:42:37PM *  0 points [-]

Even though the wikipedia page for "meaning of life" is enormous, it boils all down to the very simple either/or statement I gave.

How do we know if something is answerable? Did a chicken just materialize 10 billion light years from Earth? We can't answer that. Is the color blue the best color? We can't answer that. We can answer questions that contact reality such that we can observe them directly or indirectly. Did a chicken just materialize in front me? No. Is the color blue the most preferred color? I don't know, but it can be well answered through reported preferences. I don't know if these currently unanswerable questions will always be unanswerable, but given what I know I can only say that they will almost certainly remain unanswerable (because it's unfeasible or because it's a nonsensical question).

Wouldn't science need to do conceptual analysis? Not really, though it could appear that way. Philosophy has "free will", science has "volition." Free will is a label for a continually argued concept. Volition is a label for an axiom that's been nailed in stone. Science doesn't really care about concepts, it just wants to ask questions such that it can answer them definitely.

Even though science might provide all the knowledge necessary to easily answer a question, it doesn't actually answer it, right? My answer: so what? Science doesn't answer a lot of trivial questions like what I exactly should eat for breakfast, even though the answer is perfectly obvious (healthy food as discovered by science if I want to remain healthy).

Why still have the hard problem of consciousness if it's answerable by science? Because the brain is hard to understand. Give another century or so. We've barely explored the brain.

What if consciousness isn't explainable by science? When we get to that point, we'll be much better prepared to understand what direction we need to go to understand the brain. As it is now, philosophy is simply following science's breadcrumbs. There is no point in doing philosophy, unless there is a reasonable expectation that it will solve a problem that can be more likely solved by something else.

A scientific theory of ethics? It wouldn't have any "you ought to do X because X is good," but would be more of the form of "science says X,Y,Z are healthy for you" and then you would think "hey, I want to be healthy, so I'm going to eat X,Y,Z." This is actually how philosophy works now. You get a whole bunch of argumentation as evidence, and then you must enact it personally through hypothetical injunctions like "if I want to maximize well being, then I should act as a utilitarian."
