I’d like to say some more about questions of doubt and certainty, which were central to my recent discussion of Wittgenstein. I explored this question at greatest length in the post called “Certain knowledge”, but the conclusions there were tentative – which is to say, not certain.

To recap a little first: This question was Descartes‘s biggest passion. He wanted one and only one Archimedean point, one firm foundation that could not be doubted, on which he could build the rest of his philosophy. And to doubt that he was doubting would be self-contradictory, so the existence of his doubt and therefore of his own existence became certain. “I think, therefore I am.”

But Descartes was wrong: the existence of the thinking self can be, and is, doubted all the time. Almost all Buddhist tradition rests on just such a doubt: the self is not real. If there is an indubitable Cartesian foundation, one must take it back to “There is thinking, therefore there is being.” But is there even this? Descartes argues that to doubt one’s own doubt (or doubt one’s own thinking) is self-contradictory. To establish this point for certain, however, does require that one accept the logic law of non-contradiction – and accept it as an absolute law, brooking no exceptions ever. Graham Priest’s dialetheist epistemology denies this very point: only by allowing that certain contradictions can be true, he says, can we successfully resolve the liar paradox or Zeno’s paradoxes.

In the previous post I noted that I am completely unimpressed by Ludwig Wittgenstein’s On Certainty. What I know of the rest of his work, at least the Philosophical Investigations, has done little to impress me either. (Most of what I read serves to convince me more strongly that he is wrong.)

I suppose I’ve long been predisposed against Wittgenstein because of the unfortunate ways his thought is used in religious studies. (continue reading…)

It is probably uncontroversial to describe Ludwig Wittgenstein as one of the twentieth century’s greatest philosophers. In my less charitable moods I’d be tempted to say that this is rather like being one of Kansas City’s tallest buildings. Still, his vast influence over the philosophies that come after him is undeniable – but I often wonder why.

I’m led to think about Wittgenstein by a few recent comments from Thill, quoting a text called On Certainty. Readers might recall that in my most extensive reading of Wittgenstein to date – looking at the Philosophical Investigations – the main effect he had on my thought was to push me away from his thought and closer to the thinkers he disliked, like Plato and Augustine. But a brief look at On Certainty does even less for my estimation of Wittgenstein as a thinker. (continue reading…)

I’ve just been reading the popular neurologist Oliver Sacks‘s piece “An Anthropologist on Mars,” from the book of the same name. It’s a short biography of Temple Grandin, a woman whose life was recently made into a movie. Grandin, an animal researcher, has Asperger’s syndrome or “high-functioning autism”; she understands science, and animals, much better than she understands the social interactions of her fellow human beings.

People describing Grandin often reach first for words like “extraordinary,” “fascinating,” “remarkable.” These are not the words that come to my mind. I say this not because I find her accomplishments limited – they are major – but because I find her story very familiar. I don’t know if I would be diagnosed with Asperger’s myself; but I do know that Asperger’s is part of a spectrum, with full-blown autism on one end. At the other end, I think, one finds the behaviour of typical science-fiction geeks and absent-minded professors, in whose company I unquestionably fall.

The central features of Asperger’s syndrome are a difficulty with social cues and a narrowness of interest; one falls far outside the normal realms of human interest and interaction. (My interests are almost opposite Grandin’s, yet this makes me sympathize with her more. Where Grandin has been obsessed with animals since her youth, my mother recalls that I was the only child to be completely uninterested when a bunny rabbit was brought into our classroom.) The subtle interplay and social niceties that come so naturally to most people, must be learned deliberately and consciously, as one learns mathematics – and learning these is often far more difficult than learning math.

There are a number of philosophical implications that the diagnosis of Asperger’s syndrome might have. In today’s post, I want to focus on its implications for the history of philosophy. (continue reading…)

The work of Harvard analytical ethicist Christine Korsgaard is justly renowned, for her clever attempt to reconstruct a Kantian ethics in the abstract terms of contemporary analytical moral philosophy, without the philosophy of religion and other elements of Kant’s philosophy that contemporary philosophers find hard to defend. She has received less attention for her interesting takes on the history of Western ethics – which suggest to me some potential problems with her overall project.

In the prologue to The Sources of Normativity, probably her most important and influential work, Korsgaard provides what she calls a “very concise history” (her emphasis) of the connections between metaphysics and ethics in Western philosophy. I noted recently that the concept of obligation is central to Korsgaard’s philosophy, as it is to Lévinas’s; this prologue provides us with historical reasons why an obligation-centred philosophy might be a worthwhile project.

Plato and Aristotle, Korsgaard notes, had a philosophy focused on excellence (aretē, often translated “virtue”) rather than obligation, as do most of those who today reject Kantian and utilitarian ethics and are therefore usually lumped into the catch-all category of “virtue ethics.” Their ethics had much more to do more with what is good, what we should care about, than with what others oblige us to do. But, Korsgaard adds, in Plato and Aristotle this account depends on metaphysics, on a view of the way things really are. (continue reading…)

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.
