The papers at Georg Schiemer’s “Carnap on Logic” meeting in Munich a couple of summers ago are eventually going to appear as a special issue of Synthese. Actually, they are already in the process of appearing, as they dribble in to the Synthese “online early” list one by one.
The first one I’ve encountered is Peter Olen’s close study of the Iowa school’s (i.e. Bergmann’s, Hall’s, Sellars’s) reception — or rather mis-reception — of Carnap’s semantic works in the early 1940s. Perhaps I was not listening carefully enough when he gave the talk in Munich, but I have to say the published version strikes me as much more lucid and compelling. He documents in elaborate detail just what Bergmann and Hall (and then Sellars, as a result) got wrong, and why Carnap, despite some effort, was unable to set them straight. I hope people notice, because the misunderstanding in question has propagated itself pretty aggressively. If Fraser MacBride is to be believed, it was Bergmann’s student Herbert Hochberg who is to be held responsible for the “ontological turn” in analytic philosophy (not Quine, as Huw Price and others have made adequately clear) — and, it seems, largely on the basis of this very misunderstanding! Hochberg apparently had some influence on Armstrong, and thus perhaps at least indirectly also on Chalmers. So the misunderstanding Olen focusses on so minutely is worthy of the attention — it has a lot to answer for, and may even be partly responsible for our current efflorescence of metaontology and analytic metaphysics more generally.
I have to confess I have a personal axe to grind, as I wrote something on Sellars’s reception of Carnap a while ago, and no one paid much attention at the time. I argued there that Sellars’s early notion of a “pure pragmatics” (including the “material rules of inference” beloved of Brandom) derived from a misunderstanding of Carnap. Now Olen not only vindicates (part of) that claim, but shows in convincing detail where that misunderstanding came from and how Sellars arrived at it. Without that context, I have to admit, the misunderstanding seemed pretty outlandish and my appraisal of Sellars was therefore perhaps unduly harsh (which is no doubt why the Sellars-Gemeinde paid no attention).
