“Ontological pluralism”

Various forms of “pluralism” are making the rounds these days.  There is, for instance, the “logical pluralism” of Beall and Restall (among others), the subject of a recent book by Stewart Shapiro, which will be discussed here at some point.  But then there is also something much vaguer and murkier called “ontological pluralism,” which, amazingly, is attributed to Carnap.  Matti Eklund, for instance, considers this question in his paper in the Metametaphysics volume.  What does he mean by it? He considers various formulations, starting with the “quantifier-variance” understanding of Hirsch, in which ontological pluralism requires the quantifiers to take on different interpretations in different languages. But Eklund thinks this is insufficiently precise, as it can seem to amount to “the thesis that a string of symbols can come out true in some languages but false in others, while meaning what it actually means.” The trouble with this, he thinks, is that it “would appear to commit the ontological pluralist to a form of relativism or idealism absent from pluralist writings.” (p. 138) Continue reading

Carnap and Husserl

A few days ago I mentioned a paper by Stone on Carnap’s and Heidegger’s responses to Husserl.  It’s an interesting paper but in one respect at least it would appear to be misinformed: its view of the role Husserl played for Carnap.  First of all, it exaggerates the extent of that role; Carnap was never a “follower” of Husserl, as Stone claims in an earlier paper.  He doesn’t, admittedly, exaggerate as grossly as Rosado Haddock (from whose book I’m glad to see Stone now carefully distances himself in a footnote).   Continue reading

How Carnap sees the task of philosophy, according to Stone

An interesting paper by Abraham D. Stone on Carnap’s and Heidegger’s different, though in some ways symmetrical responses to Husserl (still unpublished, as far as I know), concludes with some pronouncements on Carnap’s conception of the task of philosophy that appear superficially plausible but don’t in the end quite cohere: Continue reading

What is a “framework,” and why does Chalmers have an opinion about this?

A few weeks ago I argued first that Chalmers’s conception of internal and external questions bore little relation to the Carnapian one it’s supposed to explicate, then that the Chalmers version is actually incompatible with the Carnap one. Chalmers says Carnap’s internal-external distinction needs to be replaced (p. 80 of his paper in the Metametaphysics volume) because the idea of a framework is too philosophically tendentious to be allowed to burden that distinction, which must therefore also be replaced by a supposedly more neutral one. In my earlier posts, I focused on Chalmers’s replacement of the internal-external distinction, and bracketed the (in a sense more fundamental) question of his replacement for Carnap’s notion of a framework. That it needs some replacement I take to be obvious; you can’t very well have any notion of “internal” if there isn’t something for concepts or questions to be internal to, a representational medium of some sort in which questions or concepts can be stated. Carnap called that medium a (linguistic) “framework.”  Why does Chalmers consider this tendentious?  Not clear.

Howard Stein appreciation

I’m glad to see that I’m not the only one who thinks of Howard Stein as something like “the greatest living philosophical historian of science,” though he himself would certainly find such a description distasteful (not the “living philosophical historian of science” part, but the superlative preceding it).  And it’s good to see his words examined closely, whatever quarrels I may have with the conclusions reached.  Howard’s papers are very dense; there is a lot in there, much more than one can possibly take in on a first reading; putting them under a microscope can only help.

Popper and Carnap again

Anyone who’s even heard of Popper knows that he advanced his falsifiability criterion (of science) in opposition to the Vienna Circle’s verifiability criterion (of meaning). What the Popper fans seem unaware of (yes, I know, they’re no longer as numerous as in the days of Helmut Schmidt’s public endorsement) is that Carnap actually responded to this criticism by pointing out that you can’t distinguish between verification and falsification except in certain special cases, which happen not to include the laws of e.g. physics. That was in “Testability and Meaning” (1936-7), which Popper praised volubly, e.g. in his Schilpp volume. But despite the fatal consequences of Carnap’s argument for Popper’s whole edifice, Popper never responded, nor, as far as I’m aware, has any of his followers. Continue reading

Tolerance in action

[Sorry, couldn’t post these past few days as the internet connection at our new apartment here in Munich wasn’t functioning.  Welcome to super-efficient Germany!  But it’s fixed now.]

Carnap was involved in the international language movement all his life. From the age of 14 — as he himself points out, before he had encountered any logical languages — he was an Esperanto enthusiast and after 1918 went to a number of international Esperanto conferences. We know from McElvenny that — without putting Esperanto aside — he became involved in Ogden’s project of Basic English. And later, in North America, he became an active participant in the International Auxiliary Language Association (I.A.L.A.) — copious notes and comments exist in his papers about the various proposals considered by the association. But the only thing he ever published on the subject, apart from the highly abbreviated remarks in his autobiography (the original passage on this subject is roughly three times as long), Continue reading

Carnap on Value Concepts

This transcription of a shorthand text from the Carnap Papers at Pitt (Archive of Scientific Philosophy) will remain its only publication in its original “German” (actually a mishmash of German and English, in vocabulary as well as syntax and word order); the journal in which my translation of it into English and a brief introduction will appear considered the possibility of publishing the original as well, but then thought better of it.   Continue reading

Carnap and C.K. Ogden

James McElvenny (now a Humboldt Fellow at the University of Potsdam) has written a dissertation, Meaning in the Age of Modernism: C.K. Ogden and his Contemporaries — not in history but in English, if you can believe it!  There is a chapter on Ogden’s interactions with Carnap and Neurath (Chapter 4: Ogden and the Vienna Circle).  McElvenny has published some papers derived from it, which I haven’t looked at yet, but the dissertation itself is terrific.   Continue reading
