Debates about realism

Lately I'm thinking that debates about realism/anti-realism are most interesting in developing a theory of realism/anti-realism. Meaning, I'm no longer finding debates about meta-ethical realism or mathematical realism interesting on their own terms. At least, not in the same way.

CPR: Intuitions and Concepts

[I'll be taking notes here as I attempt to work through the Critique of Pure Reason. This is obviously me groping for understanding, not pontificating. If you can help me learn, please speak up.]

To start off the Aesthetic, Kant introduces a number of technical terms. Here's my list of them:
* intuition
* thought
* sensibility
* understanding
* given
* concept
* sensation
* empirical
* appearance
* matter [of an appearance]
* form [of an appearance]
* pure representations


As an exercise, I'm attempting to synthesize these terms into a coherent story, using a concrete example.

The Story: A man stands outside and sees a raven.

The Story, again: A man stands outside and a raven imposes itself on his senses -- in other words, he experiences an empirical sensation of the raven. This is the sort of thing that happens to human beings all the times, and to rocks none of the time. That's because humans have a sensibility, but rocks don't. Rocks suck.

This empirical sensation results in the man having an intuition of the raven. This is his experience of something that has certain sensible properties. His hands can feel the texture of the raven, his eyes can see its outline and colors, and he can hear sounds coming from the raven. All of the particular features of this experience are part of his intuition given by sensibility.

Right now this intuition has provided the fellow with the appearance of a particular object in his mind. There are limitations on what he knows about this appearance so far. He could tell you that it was black, that the raven was warm when he touched it, that it was firm and that it had a splash of orange, but he couldn't tell you that this was something called a raven, or even a bird. That's because "raven" and "bird" are concepts, and the sensibility does not provide concepts. Anything that is particular to this guy's sensation has to do with sensibility, but anything that tries to classify or categorize what it was that he experienced (e.g. "It was a bird," "It was really fast!") requires the understanding, a different human capacity than the sensibility.

Kant further distinguishes between the matter and the form of the appearance. The matter is all the stuff provided by the particular sensation. The form is the lens (thanks Jason!) through which sensibility always has to occur. What the form of the appearance is hasn't really been made clear yet, though it will be taken head on quite soon in the sections on Space and Time.

Just to summarize: this fellow has had an empirical sensation that results in an intuition. There's an object in this intuition, and that object is the appearance of some object, given by sensibility. This appearance has a matter and a form, and sensation provides the matter. So if we're just talking about intuitions and sensibility, all that appearances have is matter, not form.

Now, the experience of seeing a raven isn't of just seeing some thing. Rather, the experience is of seeing something familiar -- a raven. That which allows us to categorize this appearance as not just something particular, but as the experience of a raven -- something we've seen before, and will see again -- outstrips sensibility. Here ends sensibility's role in the story.

If the guy thinks, "Hey, that's a raven!" then he's having a thought, and the capacity for this sort of thing is called the understanding. People have understanding; I have no idea if canines do, but I can imagine that they don't. Concepts are ways of categorizing things, and they arise from thought. Not everybody has a concept of ravens -- others might just have a concept of black birds. But both folks are having a thought about ravens, an attempt to classify this appearance as a thing of some sort or another.

This guy has judgments (i.e. cognition) about ravens. He knows that ravens have distinct things, such as a head, wings and feet, that what it does is called "flying," that it is part of a family of things called "birds" are all provided by thought, by understanding. This is all general knowledge about ravens. This is all provided by the understanding.

There is cognition provided by the sensibility too, but it's all particular. "This thing is black," or "This thing pushes back on my hands." The truth is that both of these sentences are cheats, because, at the end of the day, every time we use a concept in speech we are leaning on the understanding. We really can't have much to say about that which is provided by sensibility, and that's why "thoughts without content are empty, intuitions without concepts are blind."

Questions:
* What does "all thought as a means is directed as an end" mean?
* Could a person have a sensation without having an intuition? The sensibility is a capacity for getting representations of objects, and every representation is either an intuition or a thought (I think?). So I think that every sensation does result in an intuition, though Kant's distinction does allow for other species having some other way of acquiring intuitions.
* Kant says that appearance is the undetermined object of an empirical intuition. But who says that there's an object at all? What capacity of the mind splits intuitions up into objects? This should be part of pure intuition, right?
* Is it wrong to separate sensibility and understanding as discrete steps? Is there a cost to this? How much work is really being done by this distinction, and is it warranted.

[This post was revised on 12/16/2011. I had made some really bad errors mixing up the role of the form of intuition and concepts, and JS was good enough to point that out to me.]

A random thought on philosophy

Here's a good way of getting at the difference between bad philosophy and good philosophy. Bad philosophy strips away the insight from fundamental questions and leaves behind a stack of uninteresting details. Good philosophy, on the other hand, is able to take a stack of seemingly uninteresting details and reveal how they determine matters of fundamental interest.

This is silly.

http://www.huffingtonpost.com/sam-harris/a-science-of-morality_b_567185.html

Why is this debate happening between a pop intellectual figure and a physicist? Why is Sam Harris attempting to do moral philosophy without any training or background, and why is he engaging with the philosophical thought of a physicist (however cogent) instead of the experts in moral philosophy? Would he consider calling a really-smart philosopher to discuss the implications of physics or neuroscience?

I can think of a couple of explanations for this:

1) Sam Harris thinks that philosophy is easy. So he can do it.
2) Sam Harris thinks that philosophers are stupid.
3) Sam Harris is completely ignorant of philosophy.

I have to admit, I'm a little bit confused by the fact that people take him seriously. Sam Harris seems like a fool, as far as I can tell, and it makes me wonder whether I'm just wrong in my evaluation of him. But if I'm not wrong, then some philosophers should put him in his place. Korsgaard, please?

Outlne of the main argument of "Self-Constitution"

As far as I can tell, this is Korsgaard's picture of things

1. "Every object and activity is defined by certain standards that are both constitutive of it and normative for it." (32) For activities, a standard is called a constitutive principle in the case that "if you are not guided by the principle, you are not performing the activity at all." (28)
2. "The function of an action is to constitute an agent." (82)
3. "The function of an action is to render one efficacious and autonomous" (83). This is because being efficacious and autonomous are constitutive standards for being an agent.
4. In addition, "It is essential [/constitutive] to the concept of agency that the agent be unified" (18) This is because "in order to be autonomous, it is essential that your movements be caused by you." (213)
5. In the case of humans, unifying one's agency (through deliberation) is work that needs to be done before any self-conscious action is possible.
6. Justice is how we unify our own agency, and so "Platonic justice is a constitutive principle of action." This is identical to the categorical imperative (213).
7. All of this assures that one will be inwardly just. But one who is inwardly just will be outwardly just as well, since reasons the kind of unity you need is a unity not just of your person, but a kind of unity that counts the reasons of everyone, ala Nagel.

Is epistemic anti-realism really the same thing as losing the authority of a system of norms? I know that this isn't obvious, and I haven't accepted it naively. The worry is that it isn't. That you can still accept a norm while independently questioning its metaphysical status--that these are just entirely different things.

I don't think that they are, though. As usual, I start with Epistemic Nihilism. If you think that there are no epistemic norms then it's hard to see why you should believe an argument for epistemic nihilism--that's my main argument. I think that nihilism can't help but make practical recommendations--you lose epistemology as a source of authority if there really are no epistemic norms. It's similar to saying that the teacher isn't a fount of reasons. It's the same with epistemic nihilism--epistemology isn't a fount of reasons. You don't actually have reason to believe anything. I take this case to be fairly strong.

And what about other forms of anti-realism? I think that this is a somewhat controversial claim, but that from the realist's perspective this isn't what epistemology means. Hmm...now that I write that I realize that there's something unclear there. Am I resting on the normativity of the meaning of epistemology? Am I saying that for the realist "epistemology" means something different than it does for the expressivist? A little bit. But if so this is kinda weird. The expressivist and the realist aren't even talking about the same domain? That doesn't sound right. Anyway, metaphysical status of norms should be independent of the identification of those norms, in the same way realists about numbers are talking about the same numbers as fictionalists.

So let me try that again. It's not about what epistemology means. It's rather about the reasons that the realist accepts. The realist doesn't accept the expressivist's reasons. Now, this isn't quite right either, because it's the same reasons for both--it's just the metaphysical status of those reasons that is in question.

OK, so let me try this one more time. The issue is whether the expressivist (or any other anti-realist) can give the realist reasons that the realist will respect. On the one hand, yes, they can. They can offer reasons to believe various things, and the realist will interpret them in a certain way, and they will interpret what they are doing in a different way. But all of this is only helpful to the extent that the realist is able to interpret the reason in a realist way. If she can't, then how can we expect her to respect it? It's not the sort of thing she recognizes as having force. Oy, this is problematic too because reasons aren't the sort of thing you choose to respect. I'm not sure. OK.

Parsimony and Burden of Proof

As I reread my thesis in preparation for my oral exam tomorrow, I'm particularly struck by a poorly thought out argument in the second chapter.

In short, the argument was that the burden of proof could be shifted away from the moral realist by noting there is an unavoidable arbitrariness in epistemology. The problem with this argument is that it doesn't really respond to the parsimony requirement, as provide a route for avoiding it. That wasn't the clearest sentence I've written in my life, so let me try again.

The problem for the Moral Realist is that parsimony requires that we don't believe that which we have no good reason to believe. And the response I offer, essentially, says that there are some cases in which parsimony isn't required. There's actually no parsimony requirement for our most basic beliefs.

Here are a couple concerns with this argument:

1) Does this mean that ANYTHING can avoid the parsimony requirement? Why only things like moral realism, treating our moral intuitions as ways of getting at moral facts?

Well, not anything. It's just that some epistemic beliefs/principles are prior to the parsimony requirement. They just happen to avoid it.

2) That's not going to cut it as a response. What if we took the parsimony requirement to be our first, most basic epistemic principle?

Then there's no room for epistemology, and you can't get going. You need to take some things on without having epistemic reason to if you're going to get anything at all.

3) What happens once we have the parsimony requirement? Don't we reflect on our prior principles and conclude that they turn out, in retrospect, to be problematic since we ought not believe them due to parsimony?

This is a pretty tough challenge, I think. One way to respond to it is to tweak the parsimony requirement so that it doesn't kill epistemology, and I actually think that this is pretty reasonable. It's overly simple to say that the parsimony requirement is that we simply never believe anything without having an epistemic reason. A fine way of putting it is that we don't believe extra things, and "extra" is glossed in the following way: non-elemental beliefs that we have no epistemic reason to believe.

Reading Gibbard, Chap 4

Chapter 4--Normative Psychology

"Competing Systems of Control"--He starts by thinking about "weakness of will" cases. In this section Gibbard distinguishes between animal control system and the normative control system. The normative control system is posited to be only a motivating force for humans, and to have a lot to do with language. A norm is a linguistically encoded precept. The normative control system has a lot to do with language, and that "a lot" has to do with coordination problems and planning problems. This is just supposed to be a good start, not the end of the story. But in this section we get conflicts between normative and animal control systems.

"Conflicts with Social Motivations"--In this section we get conflicts with social motivations and the normative control system. Above we didn't have conflicts between norms. This time we have conflicts between norms. But it's not symmetric. It's the difference between two psychological states, that of accepting a norm and that of being in the grip of a norm.

"Biological Adaptation"--Some scientific speculation. He admits that more solid investigation is needed, and he invites it. The biological function of a faculty for accepting and being governed by norms is coordination. The capacity to accept norms and being in their grip are both coordination systems, though the former is distinctly human, and depends on language.

"The Biology of Coordination"--"It is in the role of language in coordinating behavior and expectations, I shall be suggesting, that we can discern what is special about accepting norms."

"Internalizing Norms"--This term refers to what being in the grip of a norm and accepting a norm have in common. Animals are capable of internalizing norms. No decision involved, it's just built into their instincts. e.g. conversational distance. Sophisticated observers can formulate these norms, though usually those who respect the norms aren't able to even notice them. "What then might we mean here by a norm? By the norm itself I suggest, we should mean simply a prescription or imperative that gives the rule a sophisticated observer could formulate." To internalize a norm is to have a motivational tendency to act on that pattern.

"Accepting Norms"--"The state of accepting a norm is identified b its place in a syndrome of tendencies toward action and avowal. This has to do with the language-infused system of coordination peculiar to humans. We accept norms in the context of normative discusion, actual and imaginary. We take positions and thereby expose ourselves to deamnds for consistency.

"Acceptance, Action, Persuasion"
"Normative Discussion and Philosophy" [Skipped these sections.]

Reading, Gibbard, Chap 3

Chapter 3: Analysis Broached

"What is Appraised as Rational or Not"--in this section he argues that beliefs, actions and emotions can all be appraised as rational or not. Some say that only voluntary things can be rationally appraised, but Gibbard thinks that beliefs are a counter-example to this, and actions aren't entirely voluntary anyway (since they have to do with intentions, which aren't entirely voluntary, I think). So there's nothing against emotions being rationally appraised, which is what he really needs for his account. You might say that emotions are rationally appraised to the extent that they're based on beliefs that can be rationally appraised (as Hume argued), but Gibbard argues that these beliefs would have to be subconscious, and only make themselves present to the extent that the person gets angry, so you might as well just say that anger is rationally evaluated.

"Rationality and Morality"--Gibbard makes several distinctions in this section in order to focus in on morality, and to give an analysis of the relationship between morality and rationality. First, he distinguishes subjective from objective morality. Subjective morality is what an agent should do given his beliefs and knowledge, and objective morality is what an agent should do if she had perfect knowledge, or something. Gibbard says that he sees no interest in objective morality, so he's only interested in the subjective stuff. Then he distinguishes between blameworthiness and morality, so that he's only giving an account of morality (which is forward looking, as opposed to blameworthiness, which is retrospective). As an account of blameworthiness he gives "iff it is rational for the agent to feel guilty over the act and for others to resent him for it." Instead, he gives an account for moral wrongness: "an act is wrong if and only if it violates standards for ruling out actions, such that if an agent in a normal frame of mind violated those standards because he was not substantially motivated to conform to them, he would be to blame." So it's an account of morality built out of the retrospective attitude of blame. Blame depends on standards of subjective wrongness and standards for responsibility, so Gibbard defines what a moral wrong is by blocking out one of the factors for blame (the standards for responsibility).

"The Norm-Expressivistic Analysis"--The previous section gave an analysis of morality, and here we get a provisional analysis of rationality. "Put roughly and cryptically, my hypothesis is that to think something rational is to accept norms that permit it." Accepting norms is a state of mind, so naturally basic. "An observer believes an action, belief, or attitude A of mine to be rational if and only if he accepts norms that permit A for my circumstances." We here get the idea that "moral norms are norms for the rationality of guilt and resentment."

"Second Thoughts"--He clarifies what he means by rationality, and I skimmed this section. Same with morality. He's interested not in what the terms mean, but rather with the particular meanings that he's associating with them. He's happy to call these terms something else.

"Structural Problems"--On this account, the question "Is it ever rational not to be moral" makes perfect sense. Likewise, we can understand perfectly well what it means to ask whether the "moral ought implies can." Another question also makes sense: "It morality of value?" The norm-expressivistic analysis gives us an interpretation of this question too: "Is it a good thing for norms for guilt and resentment to play a big role in our lives? Or might other kinds of motivation...bring many of the same benefits without the same costs." (See Nietzsche). All he's doing is showing how powerful and flexible his framework is, and trying to show you that it is a good analysis of what's been going on this whole time. "Familiar problems can be put in new form, as questions about the structure of well-founded sentiments."

Reading Gibbard, I

"The analysis is non-cognitivistic in the narrow sense that, according to it, to call a thing rational is not to state a matter of fact, either truly or falsely. None of this leaves normative language defective or second-rate. The analysis explains why we need normative language, and as it takes shape, it ascribes to rationality many of the features on which theories of normative fact insist. In many ways, normative judgments mimic factual judgments, and indeed factual judgments themselves rest on norms--norms for belief. Normative discussion is much like factual discussion, I shall be claiming, and just as indispensable."

I really need to keep this in mind when thinking about expressivism. Because of the 60s I tend to think of non-cognitivism as looking down on ethics and other normative talk, but it's really not doing that in today's age. What is at stake--the only thing at stake--is whether one can say of normative statements that they're true or false.

TMBG and Russel's Paradox

You've got to be very careful with these sorts of things, or you'll fall into Russel's Paradox.



"There's only one everything...You can put it in one pile." This comes dangerously close to saying that there is a set of everything, which would include all sets. The fact that this is a kid's song only makes things worse--corrupting the youth. They should be teaching ZFC-approved stuff to children.

Revising, rewriting, adding...

I definitely did not think I would still be doing this much work on it so close to the deadline, but here I am. Anyway, almost done; it's due tomorrow at 2 PM.

Reply to Critic, II Ctd.

I did a poor job of responding to this criticism last time, so let me try to handle it again. The reason why the criticism lands is because, in my account, I never explicate what is wrong with a paradoxical or self-defeating reason. Without such an account I leave myself wide open for misinterpretation, and I think that the objection that I considered last time is a kind of misinterpretation. So first I'll do the negative work and explain why that objection fails to land, and that will (hopefully) lead me into a positive account of what's wrong with paradoxical reasons.

Allow me to begin with the case of skepticism about the external world, a case that the objector raised. Here's the case that he raises. Suppose that we have some theory about the external world that implies that we have knowledge of that world. And then suppose that the evidence from our senses shows us that the evidence we have is compatible with us being fundamentally mistaken about our beliefs from the external world, and based on this tension we come to doubt that we have any knowledge of the external world. What's happened in this case is that we started without a belief in skepticism about our knowledge, and we end up with such a skeptical position. In between comes beliefs based on external world evidence; meaning, what got us to reject a belief that we have knowledge of the external world is a tension in our belief about the external world.

There seems to be nothing paradoxical about that. And the reason why there isn't anything paradoxical or self-defeating about that is because there's nothing that requires you to continue to believe something that motivated you to some further belief. To give another example, you might have an entire train of thought, the problems in each link of the chain motivating you to accept the next theoretical step, but that doesn't mean that you have to keep on believing the old theory, even though without it you wouldn't have made the progress that you made!

This is supposed to cause trouble for my argument about self-defeating reasons, since the argument seems to depend on the faulty premise that one must continue to believe something that was a motivating consideration.

This, however, is a bad analogy. In order to have the proper analogy you need to talk not about beliefs or knowledge that is discarded in the reasoning process, but rather reasons and norms. And once you focus on the actual reasons for skepticism that show up in the external world case, things become clarified. What is you reason for doubting that you have any knowledge of the external world in the above case? The reason is not your beliefs, but rather the tension in your beliefs. So you have a belief that you have a reason, something along the lines of "I ought not believe that I have knowledge of an area when my being completely wrong is consistent with the evidence." And there's nothing paradoxical about that at all.

Let's say that we wanted to construct a case that's really analogous--not fake analogous--to my case of rejecting epistemic norms for internal epistemic reasons. Many cases suggest themselves, and they're all pretty wacky. Suppose that the first rule of hockey was "There are no rules in hockey." Isn't this funny? Here's another one: a book that tells you on the first page, "Don't believe a single thing--including this sentence--that you read in this book." Isn't that odd? I've got one more: Suppose that you had a moral code, and one of the maxims in your moral theory is "To be moral is immoral." In all these cases you have the normative theory eating itself, more or less. And these all feel weird, precisely in the way that the external world/perception case does not.

OK, but this fails to ease our concerns, because we still haven't landed on precisely what is wrong with a self-defeating reason. Here's one suggestion of what I'm committed to (thanks to BN for the suggestion): "A thinker must be able to retain the reasons for her belief even after a change in view prompted by accepting that belief." Now, we need to be precise, because we're not interested in what the thinker concludes upon reflection after having made a judgment right now. What we're actually interested in is whether this counts as an epistemic reason to doubt epistemic realism at all. The suggestion is that my argument depends on the view that, in order for something to count as a reason, the thinker must not know that it won't disappear in the future.

If that's what I'm committed to, so be it. That would mean that I'm committed to what Thomas Nagel famously called "timeless reasons", which means that I'm committed to the view that reasons are timeless. This is a formal requirement on reasons, that requires something to be effective at all times in order for it to count as a reason at all. If that's all it takes to get epistemic realism, then fine.

But I'm not sure that I'm even committed to that, or at least nothing quite as strong as that. All I need is that, for a reason to be a reason at all, there's no way that it could be paradoxical in this sense, not that at no time in the future will this reason disappear. Now the challenge facing me is to get precise about what exactly is wrong with such a reason.

I'll start by making a distinction between formal and substantive considerations against a reason. A formal consideration against a reason is a consideration that counts against it counting as a reason at all. For example, in Nagel that a consideration is not consistent with a metaphysical conception of oneself as equally real across time counts against something being a reason at all. If it's not timeless, then it's not even a reason. A substantive consideration is a reason that stands in opposition to some reason, always countering it.

Let me begin by offering a formal account of why a self-defeating reason is not a reason. A reason must give us a clear directive on how to alter our behavior, and something that fails to do this does not count as a reason at all. According to this standard, a self-defeating fails as a reason because it offers no clear directive due to its self-defeating nature. Just as we do not know whether to believe the Cretan when he says that all Cretans are liars, we do not know whether any reason that resembles a Cretan in this way--it only counts in favor of something if it doesn't, it only doesn't count in favor of something if it does--counts as a reason at all.

Here's a substantive account of what's wrong with a self-defeating reason. Suppose that epistemology gave us an epistemic reason to doubt that epistemology gave us reasons at all. I'm assuming that this doesn't fail to count as a reason at all; suppose that it's a consideration against belief in epistemology. Here's something that seems generally true: you only have reason to promote X if all the propositions whose truth it presupposes are true. Now, what does it mean for a reason to presuppose a truth? By that, all I mean that if that proposition were false then there wouldn't be a reason. These are familiar; if it's not true that this property belongs to someone else then it wouldn't count as stealing and there wouldn't be a reason to avoid taking it for yourself. Anyway, what does a reason to doubt epistemic realism depend on? If it's an objective reason, then it depends on the truth of the proposition that there's are objective reasons. And so you have a direct contradiction in your epistemology: on the one hand you have a reason that there are no objective episteimc reasons, but you also think that its true that there are objective epistemic reasons. This explanation is completely general, it applies to any system of norms, and seems to make it impossible to make any progress on the issue.

Now, here's a good objection against this last paragraph: "A contradiction isn't exactly a great situation for epistemology either!" But now we're just running in circles. I AGREE that it's not good for epistemology to have contradicitons of any sort, but I just disagree that this can be construed into any clear epistemic reason. This provides a strong non-epistemic reason, perhaps, to reject epistemic realism. All that I'm saying is that epistemic realism is epistemically optional; it's up to you if you think that there's some non-epistemic reason for rejecting epistemic realism. Just don't pretend that this has anything to do with truth. It doesn't--otherwise it would be an epistemic reason!

In short, the example brought by the objector fails. I might rely on the formal requirement on reasons, argued for by Nagel, that reasons are always timeless. I might say that there's an even more minimal formal requirement. Or I might say that there's a substantive impasse that's necessarily brought by internal anti-realist reasons. I don't really care which one the reader likes, but I have three solid responses to the objection.

Revising

Here are the three things that I need to improve in chapter one:

1) Response to objection that alleges that one can still remove the burden of epistemic norms for an objective reason, that is lack of coherence of the system. (See two post ago)

2) Response to objection that alleges that there's nothing wrong with the "self-defeating" reasons (see one post ago).

3) Elaboration on how these issues effect the expressivist and constructivist. (I might punt on this one, I'm not sure I know enough about these positions to take an authoritative stance on them, but we'll see how the week goes.)

BN didn't have too many substantial objections to Chapter Two. That chapter needs a bit of cleaning up here and there, and its role needs to be clarified a bit in the structure of the thesis as a whole, but it's not a top priority.

The main section I need to work on in Chapter Three is the final argument, that alleges that there's nothing wrong with lacking an explanation for how moral intuitions line up with the moral truth. This section just needs development so that my point becomes more clear.

Finally, the framing of the entire thing needs a bit--but not much--work.

Reply to critics, II

Still focusing on Chapter 1, here's another objection, that I think lands a little bit harder on my argument than the previous objection I considered.

OBJECTION: "You argue, perhaps correctly, that any reason for epistemic anti-realism would either be a reason external to epistemology, or internal to epistemology. You then argue that an external epistemic reasons makes no sense, and that an internal epistemic reason doesn't make any sense either. External epistemic reasons would have to be epistemic reasons that don't draw on epistemology, so I'll give you that one. But internal reasons seem OK to me. You say that such reasons would be paradoxical or self-defeating in nature, since they would be reasons that say "Don't listen to me!" or "What I say doesn't really matter."

But let's give this a closer look. It seems as if you're assuming that a thinker must be able to retain the reasons for her belief even after a change in view prompted by accepting that belief. And that doesn't seem to be generally true.

Consider the case of skepticism about the external world. Suppose you think that you have a theory about how perception works--light bounces off stuff, hits eyes, gets processed--and suppose that same theory tells you that you could be dreaming. You also think that this fact undermines your claims to knowledge of the external world. Now, once you no longer believe that you know what the external world is like, you've also lost your grounds for accepting the particular theory of perception. But that doesn't undermine the skeptical position. So: it looks as if it's not generally required for you to retain your reasons for belief even after the change accepting that belief prompts."

REPLY: This is a complicated case that the objector raises, and we owe it to him to go through it carefully and slowly. I think that doing so reveals that the objection fails to hit the mark.

Let's start by saying what it would take to ruin my argument. In order to ruin my argument, you would have to show that internal epistemic reasons can give us reason to reject epistemic norms. I've claimed that they can't, because self-defeating norms fail to give one a reason to believe something. But this objection alleges that this is not true, and that such a reason, though "self-defeating" in some uninteresting sense, are capable of telling you "reject epistemology!" or "don't believe epistemic realism!" So this is what we need to consider.

The objection alleges that my argument goes like this...

(1) A thinker must be able to retain the reasons for her belief even after a change in view prompted by accepting that belief
(2) Therefore, if a person has a reason to reject epistemic realism, then they must still have such a reason even AFTER rejecting epistemic realism
(3) This, however, is impossible.
(4) So we can project back and say that a person never had an epistemic reason after all.


...and that (1) is false. So let's first consider whether (1) is really false, and then we'll consider whether the objector has got my argument right.

Is (1) false? Well, we would have to show that a person need not retain a belief after a change prompted by accepting that belief. The example brought is from perception, so let's deal with that case. Suppose you have a theory of perception that tells you how you gain perceptual knowledge, and something in your theory of perception tells you that you have reason to doubt perception--your understanding of perception entails that everything could seem the same to you if you were dreaming--and so you reject...well, now let's be careful. What are you rejecting? Are you rejecting your theory of perception, or are you rejecting the belief that your observations are trustworthy? The objector needs the former, but the skeptical argument needs the latter.

I think, personally, that the perceptual case is awfully confused as raised by the objector. Why not focus on an easier case? You have a book that urges you to believe many things. One of the things that the book urges your to believe is the following sentence: "Do not believe anything written in this book." The objector wants to say that we have no problem understanding what this means. After all, the book tells us to reject everything written in it, so if we trust the book then we should reject everything written in it. Only after do we realize that--Surprise!--our reason was undermined. This seems strange. Imagine if you were told, "Believe that p, though you won't have any reason to believe that p five minutes from now." This seems odd.

This reminds me of the discussion in "Possibility of Altruism" of a person plotting against oneself. There are a lot of examples that go against what the objector alleges. Here.

In short, I think it's far from clear that (1) is false, and the example marshaled by the objector certainly doesn't prove that.

But let's say that the objector is correct, and that (1) ought to be rejected. Is it true that my argument relies on this premise? I'm going to think about this a little bit more. I'll continue this train of thought tomorrow. But I think that this is enough to remove the objection from my argument.

ON SECOND THOUGHT: The above response was confused. I think that a proper reply will show that there's a difference here between beliefs and reasons, and I'll argue for that tomorrow.

Reply to critics, I

Maybe someday I'll be a world-famous philosopher and have an opportunity to reply to critics who find my work deeply engaging and paradigm-shifting. For now, my critic is my advisor who is pretty skeptical of my arguments. So here's my attempt to respond to the concerns that he raises. He attacks my central line of argument in the first chapter, which is really pretty crucial to my argument.

OBJECTION: "You say that there can be no internal epistemic reasons to reject epistemology, because any reasons would be self-defeating or paradoxical. Any such reasons, you claim, would be akin to a person who says 'Don't believe what I am saying!'

But here's one way someone might resist this argument, and I don't think that it appeals to any particularly epistemic norms. A system of norms must provide some guidance; if it doesn't, accepting that system does not allow one to guide one's behavior or belief-formation. Hence, incoherent systems are thereby shown to be such that one can't adopt them."

REPLY: This certainly seems to make sense--what good to us is some incoherent system?--but I want to move carefully through this point. Let's first consider if the objector is alleging that some norm requires us to reject epistemic realism, or if the believer is under some sort of obligation to reject epistemic realism.

Here's one thing that this objection could be saying: we have epistemic reason to reject any system of norms that is incoherent. The fact that a system of norms is incoherent gives us an epistemic reason to believe that it is false. This, I think, is a fairly weak objection. I think that there is something very confusing about obeying a norm that loses its force as soon as you believe it. (The reader does object to my contention that we can't follow paradoxical norms, but I'll take that up later). Anyway, that's not what this objection was claiming to do--it was suggesting that we don't have to rely on epistemic norms in order to reject epistemic realism, since it's incoherent.

I'll attack another straw man, as long as I'm at it: one might say that there's a requirement that goes above and beyond epistemology such that it can pass judgement on epistemology from outside it. That is, perhaps the norm(s) of coherence, that state that we have reason to reject any system of norms that is incoherent, stands outside epistemology and is prior to it. This, however, would merely place some other set of norms above epistemology. Of course, this is possible, but two things should be noted. First, the objector is usually motivated by a kind of queasiness about norms-realism in general, and it's unclear why he would feel more comfortable with accepting one system of norms governing belief rather than some other. Further, by assumption I am considered "epistemology" to cover all norms governing belief that are truth-related. (There's a debate in epistemology about the value or aim of epistemology, but we all know that epistemic reasons are more truth-related in some regard than any other system of norms governing belief, and it's that sense that I want to invoke here). So, according to my defintions and usage of epistemology, such an objection would actually concede epistemic realism to me.

Perhaps the objector might mean that there are non-epistemic (even for my usage) norms that give us reason not to accept epistemology as real. And I concede this in the thesis. Incoherence gives us a strong, non-epistemic reason to reject a system of norms, for they are of no practical use to us whatsoever. How are we supposed to be guided by norms if they're incoherent?

The objector, however, does not rest. He still claims that he has an objection. But I've exhausted the possibilities while considering that there is some sort of norm that the objector wishes the believer to respond to. Such a norm would either have to be epistemic or non-epistemic; if epistemic, I object on the grounds that such a norm would be paradoxical and self-defeating; if non-epistemic, I concede the point. What else could the objector mean?

Allow me to put some words in the objector's mouth. He writes, "A system of norms must provide some guidance; if it doesn't, accepting that system does not allow one to guide one's behavior or belief-formation. Hence, incoherent systems are thereby shown to be such that one can't adopt them."

Perhaps, then, what he means is that it is constitutive of a system of norms that they be able to guide belief or action. Anything system that is incoherent fails to be a system of norms. And so epistemology, if it is incoherent, fails to be a system of norms.

This is an interesting objection, but I don't think it's a very good one. Here's why I'm not swayed by this objection. Somebody smart once said that in philosophy there are only two kinds of replies to objections: "Who says?!" and "So what?!" First, I'll concede that part of what it means to be a system of norms is that it is able to guide belief or action. The question is, what's the cut-off between saying that a system of norms fails to guide belief-formation WELL, and that a system of norms fails to guide belief-formation AT ALL? If the idea of a system of norms that tells you to both do something and not to do it seems like a problem for you, then why is it only that MASSIVE tensions do the trick. After all, it's a fairly common occurrence where one norm of etiquette tell you not to do something, and another tells you to do that very thing. That doesn't mean that we can't accept that system of norms anymore. But if the idea was that an inconsistent system can't count as a normative system, then why don't we reject etiquette at the first sign of trouble? The reason, I think, is because inner tensions and conflicts are the signs of a bad system, one that doesn't help us very much. But this just means that we're offering a non-epistemic reason to reject a system of norms.

Let me put the point again: The question is whether coherence is definitional of something counting as a system of norms. I'd concede that guiding behavior is definitional of something counting as a system of norms, but I don't think that coherence is. That is because coherence, I think, has to do with how well a system guides behavior. But how do you tell the difference between whether a system is just failing to guide belief well, or whether it's failing to guide anything at all? This is a really tough question. (Part of the problem is that meaning is normative in some sense as well, which is an interesting twist, I think...)

I don't think it matters much. There's a good way to reply to claims that something is constitutive of something else, and that's because such an argument usually only succeeds in hiding normativity, not eliminating it. Here's how it works in this case: suppose that it's constitutive of a system of norms that it be coherent. So epistemology fails as a system of norms, and so I reject it. Fine. Call a system of norms that fails to be coherent a nystum of sorms (or whatever). It turns out epistemology is a nystem of sorms, not a system of norms. I claim that this is fine for epistemology, though, and I continue to appeal to these things as reasons for my beliefs. Then you say "Why, that's stupid, those don't count as anything that could guide your belief" and I say, "Why not?" And it's precisely at this point that you have to give me a reason of some sort or another.

In short: I chased down the objection so that it can't be giving me any normative reason to reject epistemic realism. Then, I considered the idea that it fails to count as a system of norms as a matter of meaning, but then I showed how this is just hiding a norm of belief at some other level, and I decided that this line of objection doesn't sway me. You need objective normativity guiding belief somewhere in the equation.

But there's a more challenging objection that the objector raises against me. This one alleges that there's nothing wrong with a reason being "paradoxical" or "self-defeating" in the sense in which I use it. Such a norm is only self-defeating in the sense that it defeats its own system, but that this is a perfectly understandable thing to say. I will consider that in my next post, coming in 25 hours (religious norms are guiding my action in this case).

Draft finished

Anyone who's interested in reading a draft, I've got one.

Taking Great Philosophers Out of Context: Wittgenstein Edition

"Doubt itself rests only on what is beyond doubt."

-Wittgenstein, "On Certainty"

That, together with Putnam's quote, could be taken to stand for most of what I argue, I think.

Chapter Three

I'm actually just starting this one. Here's the introduction, anyway:

In the first chapter I argued that there are no possible epistemic reasons to doubt epistemic realism. The second chapter argued that being an epistemic realist involves a degree of arbitrariness. Despite this potential arbitrariness, the vast majority of people are committed to pretty much the same epistemology. The moral realist, however, can take advantage of this potential for unobjectionable arbitrariness by choosing an epistemology that is sympathetic towards his realism. This only allows the realist to get his foot in the door, however, since the anti-realist objects that there are tensions internal to the realist’s epistemology. Presumably, the moral realist is not willing to dissociate himself from most of the world by radically revising his epistemic principles to line up with his realism. This means that his only available option is to disarm the anti-realist objections so that the tension internal to his epistemology is eliminated.

In this thesis I am not up to the task of defending moral realism against all the anti-realist objections. Instead, I will focus on one powerful anti-realist objection, the reliability challenge. This objection alleges that the moral realist is unable to explain how it is that so many of his moral beliefs turn out to be true. I focus on this objection for two reasons. First, it is considered by many to be the most disturbing objection to moral realism. Second, because I believe that reflecting on how the objection might apply to epistemology can help us gain perspective on the problem.

I will conclude this chapter, and the thesis, hoping to have convinced the reader of two things. First, that my approach towards a defense of moral realism is a promising one for the realist. Second, that continued reflection on epistemology is capable of yielding considerable insight on ethics.

Also, I changed my layout

About a week ago I spent a half hour changing my layout. Aint it pretty?
