Dispatches from the Ivory Tower

In celebration of my ten years in the blogosphere I have been compiling some of my past posts into thematic meta-posts. The first of these listed my posts on the higher-order thought theory of consciousness. Continuing in this theme below are links to posts I have done over the past ten years reporting on talks/conferences/classes I have attended. I wrote these mostly so that I would not forget about these sessions but they may be interesting to others as well. Sadly, there are several things I have been to in the last year or so that I have not had the tim to sit down and write about…ah well maybe some day!

Zombies vs Shombies

Richard Marshall, a writer for 3am Magazine, has been interviewing philosophers. After interviewing a long list of distinguished philosophers, including Peter Carruthers, Josh Knobe, Brian Leiter, Alex Rosenberg, Eric Schwitzgebel, Jason Stanley, Alfred Mele, Graham Priest, Kit Fine, Patricia Churchland, Eric Olson, Michael Lynch, Pete Mandik, Eddy Nahmais, J.C. Beal, Sarah Sawyer, Gila Sher, Cecile Fabre, Christine Korsgaard, among others, they seem to be scraping the bottom of the barrel, since they just published my interview. I had a great time engaging in some Existential Psychoanalysis of myself!

Expressivism and the T-Schema

Expressivist like Blackburn like to invoke deflationary accounts of truth as a way to save the common sense intuition that moral judgements can be straightforwardly true or false. I have elsewhere argued that this strategy fails to absolve the espressivist from giving an account of justification and, without some kind of modification, the expressivist is committed to relativism. Blackburn’s expressivism collapses into pure autobiography.

Here is another way to make the argument. Take the following claim: Eating meat is immoral. According to the deflationist this will be true just in case eating meat is immoral. This can be put in terms of the T-Schema as so,

“Eating meat is immoral’ is true if and only if eating meat is immoral

But what are to make of the right hand side of this bi-conditional? We cannot take it as naming some fact according to the expressivist. It seems we must, then, give it the expressivist meaning. Doing so yeilds the B-schema

“Eating meat is immoral’ is true if and only if Boo eating meat

This makes it clear that deflationsim about truth cannot help the Blackburns of the world avoid giving a real theory of moral justification.

Or is there some other interpretationof the right hand side of the bi-conditional?

Truth and Necessity

I have been reading Jason Stanely’s paper on names and rigid designation from the Oxford Companion to the Philosophy of Language in the course of doing some research for my frigidity v. rigidity axe-grinding. It is an interesting and informative, though technical, introduction to issues about rigidity and I will come back to its relation to frigidity in a later post… but one thing caught my attention early on. He says, 

consider Kripke’s class of strongly rigid designators (Kripke, 1980, p. 48). This class contains the rigid designators of necessary existents. That is, this class contains all and only those designators d of an object x which exists in all possible worlds, which designate the same thing in all possible worlds (viz. x). For example, the descriptive phrase “the result of adding two and three” is a strongly rigid designator, since its actual denotation, namely the number five, exists in all possible worlds, and the phrase denotes that number with respect to all possible worlds.

Is it really the case that ‘the number five exists in all possible worlds’? Isn’t there a possible world where fictionalism about math is true? In that world 2+2=4 is not true because ‘2’ stands for an existing object, viz. The Number Two, it is true because ‘in the story we tell about mathematics’ ‘2’ stands for The Number Two in just the same way that ‘Santa wears a red suit’ is true, not because ‘Santa’ picks out some guy who wears a red suit but because ‘in the story about Santa’ ‘Santa’ picks out a guywho wears a red suit. Maybe fictionalism about math isn’t actual, but surely it’s possible, isn’t it? 

We can give the same kind of argument for any proposed ‘strongly rigid’ designator. Take God for instance. It take it that Atheism is a legitimate possibility for the actual world. That is, it migt actually turn out to be the case that there is no God. Of course it might also turn out to be the case that there isn’t one. Each of these seems to me to be a metaphysical possibility, not merely an epistemic possibility. If so then there is a possible world where God does not exist (it may or may not be the actual world). Isn’t this some reason to prefer, when faced with the possiblility of a proof of necessary existence, to take my view (fix it) rather than Williamson’s (accept it)? That is, isn’t there an issue here about whether there are any ‘strongly rigid’ designators? 

Truth, Justification, and the Quasi-realist Way

In an earlier post (The Meaning and Use of ‘is True’) I argued that when discussing minimalism about truth we need to distinguish between redundancy theories (claims about the meaning is ‘is true’) and deflationism (claims about the nature of the property that the predicate is supposed to pick out). Once we see that redundancy theories conflate meaning and use we need an independant reason to accept deflationsim about truth. In this post I will argue against deflationism by arguing that it cannot account for our common sense feelings about justification in moral judgements by looking at the way that Simon Blackburn has appealed to minimalism in formulating his quasi-realist form of expressivism.

The basic problem for the deflationsist is that whatever account of moral contradiction they give will also be the correct account of contradiction in matters of taste. So ‘broccoli is disgusting’ will be true if and only if broccoli is disgusting and someone who said that it was not would really be contradicting me. From within the ‘taste framework’ broccoli is disgusting and I can just see that the Broccoli-ban and their feelings about the taste of broccoli are just objectively wrong. Of course all that any of this means is that I accept or agree with the sentiment that I expressed when I said that broccoli was disgusting. The story we tell here exactly parallels the story that is told in the case of moral judgments about cruelty, the Taliban, or whatever.

But clearly there could not be more of a difference between these two kinds of judgments. In particular, it seems obvious that this story about broccoli is just wrong. Common sense tells us that our feelings about broccoli may depend on two things. One, we may think that broccoli has a certain specific kind of taste and some people like that taste and others dislike it, which one it is may depend on what the person can taste, or it may depend on how they were raised, or just simply that they are disposed to like it or not and all of these vary from person to person. So there is nothing wrong with a person who thinks that broccoli tastes good, they simply have different tastes than ours and which you have doesn’t really matter. On the other hand we might say that broccoli has no determinate taste, it all depends on the person who does the tasting and the way that their taste buds are constituted.  Taste is a secondary property whose reality is totally mind dependant. So whether it is disgusting or not is relative to a person’s make up. Either of these common sense explanations of what is going on in the broccoli case differs dramatically from the common sense view of moral discourse. Only a madman would claim that our feelings about Saddam Hussein, the slaughter of children, truth telling, or promise keeping depended on us in either of the two ways mentioned above. Even Blackburn is not that reckless! He explicitly denies that anything like this is the right way to characterize moral disagreement. But the problem is that there is no way to distinguish these kinds of claims from the theoretical stand point of quasi-realism.

Since the theory is unable to distinguish these obviously distinguishable kinds of judgments, there must be something seriously wrong with deflationism about truth as it relates to a theory of justification. In fact, it seems obvious what is wrong with it. It very obviously and flagrantly turns moral matters into matters of personal taste. It does this by invoking redundancy and claiming that all there is to truth is its function in natural language of voicing agreement. To say that something is true is simply to repeat what we have said. If we happen to have said something about rape or the taste of broccoli makes no difference. Once we take the deflationary account of truth seriously we are no longer able to take moral discourse seriously.

Blackburn cannot respond that we can distinguish talk about broccoli and talk about genocide by the level of emotional commitment that we have to claims in one area as opposed to claims in the other because it is not inconsistent, on his view, that there be people who take broccoli as seriously as we take suffering. Thus the Broccoli-ban are every bit as serious about people who disagree with their feelings about the taste of broccoli, even to the point of putting dissenters to death. It may be the case that Simon Blackburn does not take talk about broccoli that seriously, but so what? If this is to be anything more than a mere autobiographical report what we need is a way to say that someone who did take talk about broccoli as serious as the Broccoli-ban is mistaken and further that their being mistaken is not simply an opinion of mine. Something, in short, that allows us to distinguish our talk about what depends solely on us and what does not. The deflationary theory of truth fares very badly here. It will only seem plausible if one thinks that that is all there is to truth, but this belief is not forced on us.

Not only does quasi-realism have no way to distinguish between the Taliban and the Broccoli-ban that is not mere autobiography we can see that the very same problem arises for other moral claims. Suppose someone from the Taliban were to respond to Blackburn that their views on women were the correct ones to have and that
Blackburn was wrong when he says that they (the Taliban) are objectively wrong. Let us suppose that they laugh at the idea that women are equal to men in any serious way. Then, according to the analysis that is on offer we are to conclude that what they have said is true just in case they really hold the attitudes that they say they do.
Blackburn then points out that they are ‘blind to the nature of women and the possibilities open to them’ and so on, but the important question of WHY it is that the Taliban have to agree with him on this point is left begging to be addressed. Of course by this I do not merely mean that the Taliban may irrationally refuse to admit that the evidence against them is compelling but rather the stronger claim that in some deep sense there is no way to really say which is right here. Each is saying something true when they express their moral sentiments about women. This is, of course, nothing more than relativism.
