Hilary Kornblith, Susan Haack, and Richard Jeffrey were not that far off the "top 26."
As with the earlier poll on moral & political philosophers, the poll has mainly sociological--and only partly philosophical--interest. On the one hand, it seems to me clearly right that Alvin Goldman is the preeminent living epistemologist, though I, personally, would have ranked him ahead of Quine, whose strong showing can't be based on the wide influence of his conception of "naturalized epistemology" except as a target that others attack! The strong showing of Chisholm, Sellars, Sosa, Williamson, Gettier, and Dretske is also what I would have, more or less, expected. After that, I'm too uninformed to have a strong view either way.
Alas, there were some omissions from the pool. Carnap's contributions to what is now known as formal epistemology were in the post-WWII period (I failed to realize that), though in general poll responents didn't favor formal epistemology (Jeffrey got the most votes, and did not make the "top 26"). The youthful-looking John Hawthorne is, in fact, over 50, and he likely would have made the top 20 had he been included. (Yale's Keith DeRose did the best of younger philosophers over 50 included in the poll.) A couple of readers pointed out that David Lewis's "Elusive Knowledge" was an important paper in stimulating contextualism, and that he also wrote significant papers for the development of formal epistemology. This is indeed true, but it is fair to say that Lewis was not "primarily" an epistemologist, and there is always a risk that "David Lewis" (like "W.V.O. Quine" perhaps) would simply rise to the top in virtue of his singular importance in Anglophone philosophy of the post-war period.
Comments are open for comments on the sociological and philosophical aspects of the results.
