Odds and Ends

When setting up my “Lewis blog”:http://lewisblog.weatherson.org, I should have noted that there’s already a very good weblog devoted largely to David Lewis’s philosophy, namely “Wo’s weblog”:http://www.umsu.de/wo/. Wo himself left a very clever suggestion on my Lewis blog for how to solve the puzzle about defining theoretical terms I wrote about yesterday. I think that he nicely solves the problem I thought I’d found for Lewis.

Barry Loewer wrote in to tell me about a summer course that is being run next July in Budapest on “Descrying the World in Physics”:http://www.ceu.hu/sun/SUN_2006/brief_course_descriptions.htm#Philosophy%20and%20Physics. It features Barry, David Albert, Tim Maudlin, Katalin Balog Carl Hoefer and David Papineau. It looks extremely interesting, and you get to spend time in Budapest while attending it. Here’s a brief description.

bq. There is a tradition within the history of physics that proposes that our world may have a complete fundamental physical theory. The course will examine this tradition and especially its prospects in view of foundational issues raised by quantum mechanics and statistical mechanics. We will be especially interested in the problem of “descrying” (that is locating and explaining) various features of the macroscopic world, especially the special sciences and features of human mentality and agency within the ontology and laws of fundamental physics.

Some of the time, perhaps most of the time, I think this is the single most important philosophical problem.

Finally, two more links to papers on Scott Soames’s book.

Defending Functionalism

Over at the new “Fake Barn Country”:http://blogs.brown.edu/other/philosophy/ (now with _real_ fake barns!) Jonathan Ichikawa “argues against functionalism about belief”:http://blogs.brown.edu/other/philosophy/2005/10/against_beliefdesire_functiona.html. I’m always up for defening functionalism, so I want to resist.

Summer in Vienna?

For those of you who like slightly longer than usual conferences, the Vienna Circle runs two week summer institutes every year. Next year’s features ANU’s own Geoffrey Brennan, along with Hartmut Kliemt, on philosophy and economics. Details “here”:http://www.univie.ac.at/ivc/VISU/.

A Puzzle About Defining Theoretical Terms

There seems to be a fairly serious problem with the theory set out in Lewis’s “How to Define Theoretical Terms”, which I’ll set out here. I might be misinterpreting Lewis, and if so I’d like to know. And I’m probably just be repeating something that has been said elsewhere already, and if that’s so I’d really like to know. So comments from Lewis(iana) experts much appreciated.

Lewis Blog Updates

After some technical glitches came up, I moved the Lewis blog to a new site. The new address is:

bq. “http://lewisblog.weatherson.org”:http://lewisblog.weatherson.org

That address is still propagating through the internet, so if it doesn’t work for the next few hours, don’t panic!

I’ve also moved and improved the RSS feed.

bq. “RSS Feed for Lewis Blog”:http://lewisblog.weatherson.org/index.rdf

It should now have full entries in the RSS feed.

I realised while doing this that I might now have full entries in the RSS feed enabled for TAR. If anyone is reading this using an RSS reader and has noticed that they aren’t getting full entries (not that I use extended entries on TAR very often) could you let me know and I’ll try and fix the problem. For example, this entry should have a Lewis quote at the end. If it doesn’t, you aren’t seeing the full entry.

Lewis Blog

In the spring I’ll be teaching a seminar on Lewis at Cornell. I’m hoping to write extensive lecture notes for each week and post them to the website, with the thought that the notes collectively will form a worthwhile extensive work on some core features of Lewis’s philosophy. As part of the process of doing this I’ve set up a sub-blog to record my draft lelcture notes, reading notes, and assorted Lewis thoughts.

bq. “Lewis Blog”:http://tar.weatherson.org/notes/
“RSS feed”:http://tar.weatherson.org/notes/index.rdf

I might cross post some stuff here, or perhaps link in the sidebar to posts there, but it would overwhelm TAR to have 2000 words a day of Lewisiana appearing. There are three kinds of posts there: drafts of the lecture notes (inc. perhaps final drafts), notes on particular papers, and assorted comments working out or defending something to be said in the other sections. There is one of each so far in the blog. There will be plenty of overlap between posts – the lecture notes may be cut and paste in part from other posts. But I’d be very interested in feedback people have. Hopefully there will be lots interesting appearing there – and I’ll have a course ready to run by the start of next term!

For the Record…

Just in case “anyone was confused”:http://leiterreports.typepad.com/blog/2005/10/ask_a_philosoph.html, the following two sites are distinct.

“Ask a Philosopher”:http://go.to/ask-a-philosopher is a service run out of Sheffield that has been in operation for years. Its purpose is to solicit questions from the public of a broadly philosophical nature and have professional philosophers answer them.

“Ask Philosophers”:http://www.amherst.edu/askphilosophers/ is a service run out of Amherst that has been in operation for weeks. Its purpose is to solicit questions from the public of a broadly philosophical nature and have professional philosophers answer them.

I was told by a former graduate student at a leading philosophy program that there is some professional tension between the sites. There certainly is a notable lack of linkage between the two sites, despite their apparently complementary aims. Anyway, feel free to peruse, or contribute to, either site.

Soames on History

In the “thread below”:http://tar.weatherson.org/archives/004533.html on Michael Kremer’s review of Scott Soames’s history of the 20th century, Soames has left an interesting comment which I’d recommend readers look at. One thing I especially wanted to highlight is that he has posted his reply to _Philosophical Studies_ symposiumists on volume 1 on “his website”:http://www-rcf.usc.edu/~soames/, which as “Dave”:http://fragments.consc.net/djc/2005/10/more_online_pap.html notes contains a large crop of papers. The reply is “here”:http://www-rcf.usc.edu/~soames/replies/What_Hist_for.doc (Word). [Just as I wrote this I noticed Ian Proops’s comment that his paper is also online – it is “here”:http://www-personal.umich.edu/~iproops/practice/ProopsonSoames3.pdf (PDF).]

Here are a few extended quotes from the introduction to Soames’s paper and the introduction to the response to Proops.

bq. I will begin by replying to the constructive, substantive criticism of Stoljar and Burgess. After that, I will take up the harsher criticism focused on matters of historical scholarship presented by Proops and Sainsbury. In addition to setting the historical record straight, I will locate the roots of the dispute in a conflict between the history-for-history’s-sake conception implicitly advocated by Proops and Sainsbury and my own philosophically and pedagogically motivated approach to the history of the subject. In doing so, I will articulate and defend the goals of philosophically oriented history, and use the resulting conception both to illuminate my discussions of individual philosophers, and to clarify how they contribute to what I take to be the leading achievements of the analytic tradition.

bq. …

bq. We now turn to less philosophically, and more historically, focused criticism – which, as I shall argue, raises fundamental questions about the proper aims of work done by philosophers, for philosophers, in the history of their subject. Ian Proops’s critique of my treatment of the metaphysics and epistemology of Moore and Russell is of this sort. He beings with what he labels a conundrum – Did I take myself to be doing history of philosophy, and so to be making claims about what the philosophers said and meant, or was I merely using their writings pedagogically? Of course, I took myself to be doing both. The fact that Proops sees a chasm between these two aspects of the same enterprise is, in my opinion, indicative of a larger failure of perspective that informs his remarks. My task was to extract from the voluminous writings of the philosophers covered, done throughout their entire careers, those lessons that every analytic philosopher today, and every student, should be aware of. Doing this required making their major achievements and failures as clear and comprehensible as possible, but it did not require – or allow – following every twist and turn in the development of their thoughts. Nor did it mean, in every case, reproducing the exact route to a philosopher’s most important results, if simpler and more comprehensible routes were available that preserved the philosopher’s central insights.

bq. This is the strategy routinely used to introduce students to historical achievements in logic, like Gödel’s incompleteness and Tarski’s indefinability theorems. Our confidence in what constitutes progress underwrites our judgments of what was essential and what inessential in the texts of great logicians. The same is true in philosophy. It is because philosophy has progressed, and we know more now, that we can separate the essential from the inessential in presenting the contributions of a philosopher like Russell. That is the spirit in which I approach the task. The opposing spirit denies philosophical progress, or at best adopts a value-neutral stance, and as a result takes the historical enterprise to consist simply in elucidations of all the different strands of past philosophical thought, and identification of lines of influence. There are, of course, other less tendentious routes to this antiquarian conception of the history of philosophy, but they are beside the point. My aim was to present an historically accurate picture of the main lines of progress in the analytic tradition.

I’m mostly posting this here because I think it would be a useful topic to debate. I’m fairly sympathetic to the idea that we can write histories of philosophy that are useful for teaching the students what has been gained through philosophical work, and that this is worth doing even at the cost of eliding some details. As Soames notes in his reply to Sainsbury, in this kind of history, if a philosopher says “I’m pretty confident that p, but there are concerns about how p could be true in areas A, B and C that I’m not 100% sure how to address and can only gesture at D, E and F in response”, often the best way to summarise this in a thematic history book is as “p”. So I’m perfectly happy to grant Soames the appropriateness of his approach.

There is one thing I find rather puzzling though about this line of defence of his books. If the point is to “present an historically accurate picture of the main lines of progress in the analytic tradition”, one might have hoped for a little more _breadth_ of coverage. Soames spends a lot of his time in this response defending himself against the claim that he should have spent more time on the details of, especially, Russell’s views. But I think in many ways, especially given the stated aims, he should have spent quite a bit _less_ time on the authors he actually covered and covered quite a few _more_ philosophers.

Possibly for any century before the 20th, the best way to present its history would be to focus on the works of the greatest philosophers. But surely that’s not the way to present the 20th century. There were so many philosophers making so many contributions, be they positive or negative, that Soames’s almost exclusive focus on the greats ends up distorting the picture.

So, for example, we get a rather detailed study of _The Concept of Mind_, with some fairly trenchant criticisms. There’s a lot there that’s valuable. But wouldn’t the student have got a better guide to analytic progress with a chapter that started with a brief discussion of Ryle and his perceived errors, then went on to say how Smart, Armstrong and Lewis proposed theories that built on Ryle’s virtues while attempting in their own ways to correct the (quasi-)behaviourist excesses? Or instead of going over the back-and-forth between Austin and Ayer about sense data in quite so much detail, simply introduce their positions and their most important innovations and then discuss the most important contemporary work on either side of that debate?

We don’t, or at least I don’t, teach logical results by looking at the work of the original logicians. And much of the history of philosophy could be done the same way. We could, for instance, teach Godel’s completeness theorem by name-checking him and then working through the details of Henkin’s proof. And we can teach at least some aspects of history of philosophy the same way. But Soames sticks to the canonical writers. So we’re left, by necessity of space, with not quite enough _depth_ for a dedicated historical work on the authors covered, but without the breadth of coverage needed for a genuine survey of the important trends in the first full century of analytic philosophy.

Having said all that, this is probably as good a time as any to post my contribution to the other part of the _Philosophical Studies_ symposium. My job was to write on the Wittgenstein to Grice part of the book, and it’s here.

bq. “Doing Philosophy With Words”:http://brian.weatherson.org/dpww.pdf
(The link now works – thanks to Michael Kremer in comments.)

I should say that I now think there is a somewhat serious mistake in the second last sentence of the section on Ryle. I think I managed to totally muddle the story of the battle between the Cartesians and the materialists that Ryle closes _The Concept of Mind_ with, and so my appeal to that story in defending the claim that Ryle wasn’t as much of a behaviourist as Soames suggests is probably a blunder. The story still suggests that Ryle’s position is quite different from the simple behaviourism that Soames attributes to him, but it’s not the evidence for my interpretation that I say there. _C’est la vie_.

Given what I said above, I should stress that my complaint about Soames’s interpretation of Ryle isn’t that he simplified Ryle’s view. That’s a necessary evil of the kind of book he’s writing. It’s that by simplifying in the way he does, in the direction of behaviourism rather than dispositionalism, he’s blocked himself off from telling an interesting story that the well-informed student should know about the importance of Ryle to the development of modern functionalist theories of mind.

Puzzle Blogging

I was looking back over old Mathematical Olympiad questions, and I came across this question which seems to require very little mathematical insight as such to solve. It’s a very hard puzzle, but the skills needed to solve it aren’t that much different from the skills needed to solve the puzzles in the weekend newspapers. The puzzle is from day 1 of the 1989 Olympiad, and I’ve reworded it so as to make the terminology a little easier to follow.

Divide the numbers 1, 2, 3, …, 1988, 1989 into 117 sets of 17 numbers such that (a) each number appears in exactly one set and (b) the sum of the numbers in each set is the same.
