I have just started trying to make my way through Ludwig Wittgenstein’s Philosophical Investigations, and so far it has had a surprising effect: it has made me more of a Platonist. Which is exactly the opposite, I think, of what Wittgenstein intended.

Wittgenstein begins the book with a critique of a passage in Augustine’s Confessions, on a subject whose Christian significance is not discussed. Speaking of his childhood, Augustine – a Platonist – explains how he came to understand concepts:

When they (my elders) named some object, and accordingly moved towards something, I saw this and I grasped that the thing was called by the sound they uttered when they meant to point it out….. Thus, as I heard words repeatedly used in their proper places in various sentences, I gradually learnt to understand what objects they signified… (Confessions I.8)

On such an account, Wittgenstein thinks, words have a meaning correlated with them, and their meaning is an object they stand for. Wittgenstein replies that such an account is true, at best, only of nouns. It is not true of other parts of speech. To argue his point he gives the following example, often cited in others’ expositions of Wittgenstein’s thought:

Now think of the following use of language: I send someone shopping. I give him a slip marked “five red apples.” He takes the slip to the shopkeeper, who opens the drawer marked “apples”; then he looks up the word “red” in a table and finds a colour sample opposite it; then he says the series of cardinal numbers – I assume that he knows them by heart – up to the word “five” and for each number he takes an apple of the same colour as the sample out of the drawer. — It is in this and similar ways that one operates with words. — “But how does he know where and how he is to look up the word ‘red’ and what he is to do with the word ‘five’?” — Well, I assume that he acts as I have described. Explanatons come to an end somewhere. – But what is the meaning of the word “five?” – No such thing was in question here, only how the word “five” is used. (Philosophical Investigations I.1)

I hope that Wittgenstein’s arguments get better as the book goes on, or that this excerpt turns out to be only a piece of a larger and better argument. For it strikes me as rather a poor piece of reasoning. Indeed the meaning of the word “five” was not in question in the transaction – but neither was the meaning of the word “apples,” for both participants already knew what the word meant.

Does P.Z. Myers love his wife?

I’ve previously written against NOMA, Stephen Jay Gould’s assertion that “science” and “religion” are completely compatible because they represent two incommensurable domains of inquiry. But there’s at least as much of a problem with the other extreme, the view of New Atheists like Richard Dawkins that the two are completely incompatible because “science” refutes “religion.” (Few seriously assert incompatibility in the other direction, to reject science. Creationists, for example, typically proclaim their acceptance of science except where it conflicts with the Bible – thus the popularity of intelligent design, sold as a scientific theory.) Both of these views, to my mind, are almost painful in their oversimplification of the matter. There is incompatibility between certain parts of each domain. Many beliefs called “religious” are perfectly compatible with the evidence from controlled hypothesis testing; many aren’t. In the “scientific” domain, the only views I can think of that are incompatible with all “religious” belief are those which involve scientism: the belief that the only valid forms of knowing are based on the practice of science. (It’s worth stating repeatedly that this belief cannot possibly itself be based on the practice of science, and is therefore self-refuting.)

New Atheists often don’t want to admit this point. When they accept common-sense views at odds with their exultation of science as the only true way of knowing, they do it by equivocating on their definition of “science.” One finds the point in a recent exchange on P.Z. Myers’s blog. Responding to Larry Moran, Myers attacks what he calls:

the bizarre claim that “No scientist that is also a decent human being subjects all her/his beliefs to scientific scrutiny.” I think otherwise. There is a naive notion implicit in that statement that scientific scrutiny is somehow different from critical, rational examination. I’d argue the other way: no decent human being should live an unexamined life.

“Critical, rational examination,” eh? If that’s all science is, then every theologian is a scientist par excellence. I don’t think that’s a claim the New Atheists want to be making. Rather, the “science” they are defending is a) completely empirical, and b) based on the controlled experimental testing of hypotheses. So John Pieret responds to Myers by saying:

Really? What tests did you do on yourself to see if you love your wife and children? Hormone testing, eegs, what? Thinking about things is not “science” per se. Science is empiric investigation. Nor is the question whether “love” can be scientifically investigated, the question is whether individual scientists do it before they decide who they love.

Why should we do anything?

Possibly the biggest philosophical question on my mind is this: why should we do anything at all? Or, why should we do one thing and not another? What is it to have a reason for action, a reason to do anything? It’s difficult to have a coherent ethics without answering this question in some respect; but in some ways it’s even more difficult to answer the question itself.

There are, I think, two basic classes of answer to this question, which analytic philosophers classify as internalism and externalism with respect to ethical motivation. On an internalist view, to have a reason to do something is to have a motivation, perhaps even a desire, to do it. If you don’t at some level want to do something, or at least feel or believe that you should do it, then you shouldn’t do it. On an externalist view, by contrast, reasons are independent of us. There are things we just should do, period, whether or not we have any desire or other motivation to do them.

Each position faces wrenching difficulties. The externalist view is always subject to the laughing, scathing criticism of a Nietzsche. If you can’t tell me why I would want to do something, then bollocks to your “should.” I’ll do what I want instead. External reasons don’t feel like real reasons; Bernard Williams, indeed, has argued that they only really become reasons for action if we acquire motivations to do them. Yet the internalist view seems to collapse into relativism and conservatism. If our existing motivations are the only source of reasons for action, then how can those motivations ever be criticized? On what grounds can you tell Pol Pot he’s doing the wrong thing by killing his citizenry? You run, effectively, into the problems with classical relativism, which show up in a variety of ways, such as the political problems of postmodernism, or the problems of contradiction for spiritual growth.

Some way of reconciling internalism and externalism, without the problems of each, seems necessary. But what way?

What makes the question of ethical internalism and externalism still more intriguing is that it seems to parallel a very similar theoretical question about truth. Could there be a truth we can’t know? Say, a kind of knowledge only achievable by gods and not humans? If so, on what grounds can we say that something really is a truth, if we can’t know it? If not, do we not collapse back into the problems of relativism, where everything is subjective, since knowledge is reducible to our own minds?

Do Speculative Realists want us to be Chinese?

I’ve lately been trying to start understanding Speculative Realism, a contemporary movement within “continental” philosophy. Speculative Realism is of particular interest to me because, it seems, it is one of the first philosophical movements whose social network is focused on the Web. (One of its leading thinkers, Graham Harman, has his own regularly updated blog.) This is not yet the future I’ve been starting to imagine where the Web replaces universities and book publishing as philosophy’s institutional locus, since most if not all Speculative Realists are academics. Still, it’s an interesting first step.

Now what about the content of Speculative Realism, the ideas? It’s a difficult school of thought and I’ve only scratched the surface, by scanning of some of the websites. I am certainly not in a place to evaluate this emerging tradition’s arguments, not yet at least. But to help myself and others think through what Speculative Realism might mean, I’d like to try some preliminary comparison – what Charles Tilly would call “individualizing” comparison, the attempt to understand one phenomenon by drawing connections to others.

As I understand it so far, the most central idea in Speculative Realism is a critique of what the French Speculative Realist Quentin Meillassoux calls “correlationism.” I pinch Meillassoux’s definition of “correlationism” from Skholiast’s blog: correlationism is “the idea according to which we only ever have access to the correlation between thinking and being, and never to either term considered apart from the other.” Correlationism is an idea associated above all with Immanuel Kant’s epistemology, according to which our knowledge is limited to categories of human thought; it is thereby anthropocentric, focusing epistemology and metaphysics too much on the human subject and not enough on objects in the world. (Thus Speculative Realists like Harman often refer to their thought as “object-oriented philosophy,” a philosophy focused on the objects of knowledge, as opposed, presumably, to the “subject-oriented philosophy” of Kant.)

The first comparison that came to my mind when I read about this was one that I doubt Speculative Realists would find flattering: Ayn Rand. Continue reading →

What does postmodernism perform?

The term “postmodernism” (or “poststructuralism”) is notoriously elusive; it’s sometimes said that if you think you know what it is, you don’t. But that doesn’t stop its practitioners from talking about it, and I don’t think it should stop anyone else either. I will use “postmodernism” to refer to a set of ideas, widely held among academics in the past 30 years, which takes inspiration from Jacques Derrida and Michel Foucault, and denies the worth of claims to truth. One will frequently find postmodernists (John Caputo is one of the more explicit about this) claiming that “the truth is that there is no truth.”

The claim that there is no truth is false. It contains a contradiction that cannot be resolved unless one takes it to mean something very different from what it appears to mean. Nor is this one of that narrow group of paradoxes which could be taken as true on the grounds of Graham Priest’s dialetheism. Priest tries to argue that most of the problems with contradiction stem not from accepting some contradictions, but from accepting all; but if one accepts “there is no truth,” one comes much closer to allowing all contradictions in. Indeed postmodernists often approvingly quote the philosopher of science Paul Feyerabend in telling us that “anything goes.”

It is not true that there is no truth. What is crucial about this and other postmodern claims, however, is that its truth value is not the point. Like Stanley Fish, postmodernists shift our attention away from contradiction and truth entirely, claiming they’re not the important thing. (Caputo at one point approves one of his opponent’s moves because “it drops the stuff about contradiction and actually addresses the issues.”) Drawing on J.L. Austin’s theory of speech acts, postmodernists will argue that the reason to make such a claim against truth is its performative dimension. The point, that is, is not what the sentence says, but what it does.

It is on this last point, however, that the evidence against postmodernism seems strongest. What, exactly, has postmodernism accomplished? I have previously mentioned cognitive dissonance and spiritual transformation as reason to be concerned about contradictions. But these are typically not at the forefront of postmodern concern. Rather, most postmodern writers express some sort of concern for marginalized political groups – women, gays, transgendered people, the poorer or working classes, people in nonwhite racial groups, people from colonized societies. But what has postmodernism actually done to improve their situation?

Truth and contradiction beyond propositions

What do Augustine, Gandhi, Śaṅkara, Marx and Mao all have in common? Something quite important. But before answering this question, a brief excursus on Marx’s inspiration, G.W.F. Hegel.

In reading Graham Priest’s work, I was particularly struck by a point Priest makes at length in his Stanford Encyclopedia article: that Hegel believes there can be true contradictions, and is in that sense a dialetheist. I think Priest is technically right, but the point can be a bit misleading.

First, Hegel accepts the normative force of non-contradiction, in a way that Priest also does but tends to push to the sidelines. That is: while it’s possible for contradictions to be true, there’s also something about them that is epistemologically bad. As I noted last time, Priest accepts this point himself, so that when he says “What is so bad about contradictions? Maybe nothing,” he is effectively being disingenuous for rhetorical effect. For Priest, contradictions are epistemologically bad only in that the probability of a contradiction being true is generally low. For Hegel the problem with contradictions is something significantly bigger: a true contradiction eventually and inevitably becomes false.

This point leads into a bigger difference that goes well beyond Hegel’s and Priest’s work, which is what I really want to address today. Priest generally imagines contradictions as existing between linguistic truth-bearers of some description. He says at the beginning of the SEP entry that “we shall talk of sentences throughout this entry; but one could run the definition in terms of propositions, statements, or whatever one takes as her favourite truth-bearer: this would make little difference in the context.” But some objects taken to bear truth could, I think, change the nature of the claim significantly. Priest’s truth-bearers are statements, beliefs, propositions – all mere linguistic mental or verbal objects. But not everyone has taken truth-bearers to be of this kind. The most vivid exception may be Saint Augustine, about whom Alasdair MacIntyre put the matter beautifully:

for Augustine it is in terms of the relationships neither of statements nor of minds that truth is to be primarily characterized and understood. “Veritas,” a noun naming a substance, is a more fundamental expression than “verum,” an attribute of things, and the truth or falsity of statements is a tertiary matter. To speak truly is to speak of things as they really and truly are; and things really and truly are in virtue only of their relationship to veritas. So where Aristotle locates truth in the relationship of the mind to its objects, Augustine locates it in the source of the relationship of finite objects to that truth which is God. (Three Rival Versions of Moral Inquiry, p. 110)

Here not merely statements or beliefs but things are true – by virtue, I think, of their genuineness, their closeness to a Platonic Form of goodness which, for Augustine, turns out to be God himself. Continue reading →

Dialetheism

In response to last week’s post about contradictions, a reader who goes by “skholiast” (who has his own blog, Speculum Criticum Traditionis) pointed me to the interesting work of analytic philosopher Graham Priest, author of works with provocative titles like “What is so bad about contradictions?” Priest advocates a position that he calls dialetheism, from the Greek for “two truths,” according to which a belief or statement and its opposite can both be true – even at the same time and in the same respect, directly contradicting Aristotle’s classical law of non-contradiction. He concludes the article with this provocative claim: “So what is so bad about contradictions? Maybe nothing.”

Dialetheism is easy to mock. Indeed, the first I’d heard of it, and the only time I’d heard of it before skholiast’s post, was in two of Ryan Lake’s Chaospet comics that made fun of it. Lake’s comics note apparent problems with dialetheism: if nothing is bad about contradictions, as Priest suggests, then doesn’t that basically allow one to say anything at all? Doesn’t one then just immediately solve every hard problem without having to think about it, by saying (as Lake’s character Nester does) that “the mind both is and is not the brain”?

Stanley Fish, self-proclaimed “contemporary sophist,” recently weighed in on the “religion and science” question in the New York Times. For him, the chief problem we have in this area is that we’re too bothered by contradictions: “The potential for logical conflict, however, exists only under the assumption that all our beliefs should hang together, an assumption forced upon us not by the world, but by the polemical context of the culture wars.”

As a historical claim, the latter part of the sentence is laughable and merits no consideration: it takes very little research indeed to find that the drive for logical consistency far predates any modern culture wars. It can be found not only in Plato, its most famous advocate, but also in Augustine, in Aquinas, in Śaṅkara and Kumārila. One might be tempted to find an exception in Nāgārjuna and his Madhyamaka school, which try to avoid having any position whatsoever; but even Nāgārjuna relies in his arguments on the assumption that our positions should not contradict each other – should make logical sense. Fish is smart enough to know this point; the claim that the drive for consistency is a product of the contemporary culture wars can only be understood as a deliberate falsehood, a lie.

More interesting is the normative claim, the view that we shouldn’t be bothered by contradictions. After all, if that’s true, Fish may be entirely justified in lying. Continue reading →

One reason I turn back to premodern philosophies so much is that they often show us questions larger than those generally asked in philosophy today. Especially important among these: “what kind of life should I live?” What sorts of major life decisions should I make? It still surprises me how rarely academic philosophers concern themselves with these questions, when we spend so much time teaching people in their late teens and early twenties – for whom these questions are in the foreground.

Lately in my mind I’ve been tossing around the hypothesis that the answers to the question “What kind of life should I live?” roughly boil down to three – and that each of the three is tied to some sort of metaphysics, a theoretical as well as a practical philosophy: Continue reading →

Philosophy and science: comic takes

In light of several recent posts about philosophy and natural science, I thought I’d link to a pair of recent strips from two of my favourite webcomics, Randall Munroe’s XKCD and Ryan Lake’s Chaospet:

http://xkcd.com/675/
http://chaospet.com/2009/12/14/164-it-goes-both-ways/

The two comics together nail it all pretty well, I think. Make sure to hold your mouse cursor over each comic strip for a few seconds to get the author’s comments, too.

While I’m linking to philosophical webcomics, I should also mention Ryan North’s highly enjoyable Dinosaur Comics. Longer post coming later today.
