In his 2006 “The Transformation of American Philosophy” (available through the APA web site), Nicholas Rescher refers to the enormous growth in the philosophy profession:
The discipline presently has more than 8,000 members, and the comprehensive Directory of American Philosophers for 2004-05 lists some 14,000 philosophers affiliated to colleges and universities in the USA and Canada, while in the late 1930’s, on the eve of World War II, the membership of the American Philosophical Association stood at some 750.
These numbers are a bit tricky. We don’t know how large a proportion of philosophers belonged to the APA in the Thirties (I know many that don’t today), and we don’t know how many Canadian philosophers did (Rescher’s second figure includes Canadians; the number of American philosophers in 2004/5 is given by the Directory as 12,703). Moreover, strictly speaking this latter figures represent philosophers affiliated to philosophy departments in colleges and universities; there is evidence that more and more philosophers are being housed outside such departments. But the trend is clear.
Toward the end of his 2003 Philosophical Analysis in the Twentieth Century, Scott Soames makes an observation superficially similar to Rescher’s:
In my opinion, philosophy has changed substantially in the last thirty or so years. The number of philosophers has exploded, the volume of publication has swelled, and the subfields of serious philosophical investigation have multiplied. Not only is the broad field of philosophy today far too vast to be embraced by one mind, something similar is true even of many highly specialized subfields (Soames, op. cit. vol. II p. 463).
Both maintain that as one result of this increase in size, “balkanization reigns supreme” in philosophy today (Rescher’s words). One result of this, Rescher notes, is democratization within the profession. With so many more philosophers working in so many more subfields, it is becoming increasingly difficult for a few individuals and departments to dominate the whole. Another result is that American philosophers do not influence the larger society; for the Balkanization is such that they cannot even influence each other. A third result, referred to both by Rescher and Soames, is that a history of American philosophy is impossible to write. As Soames puts it, such a history
…would look, not like one linear and integrated story but like many distinct and overlapping stories…It is, I think, a mistake to look for one big picture of analytical philosophy in this era. What we need is a collection of more focused pictures, each giving a view of the major developments of related lines of work, and each drawn with an eye to illuminating the larger lessons for work in neighboring fields (Soames, vol. cit. p. 464).
Though both Rescher and Soames refer to a huge increase in the size of the philosophy profession, they date it differently. Rescher is referring to the whole 65 years from just before World War II until the 2004/5 edition of the Directory of American Philosophers. Soames is just referring to the 30 years before his writing, or 1973-2003.
Figures I have developed from the Directory of American Philosophers tell a somewhat different story than Soames’, and a more nuanced one than Rescher’s.
In 1964-5, the first year of the Directory I could get, the number of philosophy faculty members was over 4755 faculty members.
(Pause for explanations: “philosophers” is active faculty plus grad students plus emeriti. For various reasons, I believe that the Directory's category of faculty members, those holding permanent positions in philosophy departments, is a better indication of the size of the profession than is "philosophers." The Directory’s numbers, as I mentioned in a previous post, are at best approximate; it is the trends they indicate which count. Even these are not always accurate: early on, the Directory had problems getting people to return its questionnaire, which is one reason why its then-editor, Archie Bahm, was careful to say “more than 4755.” Still, 4755 is the figure we have, and the only figure we are likely to get. Same for the others)
By 1972-3, when Soames’s time period begins, faculty had risen to 6870—a 44% increase in just eight years. This presumably reflects the booming job market of the 60’s. By 2004/5, the number had increased to 8567, a further increase of 26% in 30 years. In other words, the rate of increase after 1972/3 decreased by a factor of slightly more than 5.
The enormous increase in size of the philosophy profession thus occurred before Soames dates it. Indeed, during the last ten years of Soames's thirty year period (plus one year--i.e. 1972-3 to 1994-5), the number of philosophy faculty shrank by a couple of hundred (perhaps more, depending on the identity of the 1919 “unknowns,” as noted in a previous posting). The increase in the overall number of “philosophers” from 11,184 (1994/5) to 12,703 (2004/5) occurred entirely within the ranks of emeriti and graduate students. The latter have had a particularly “explosive” 163% increase in the last ten years.
I’ll have more later, but right now I want to pose a question. In 1973, philosophy faculty amounted to 6870 tenured or tenure track professors. The discipline was unified in that there were several figures whom you had to be acquainted with in to be a credible member of it: people like Quine and Davidson, among logicians/philosophers of language; Rawls and Nozick among social philosophers. A central debate, over Kripke’s theory of reference, was rocking the entire profession; but it was conducted, in the main, by only a couple of dozen philosophers.
Can the total Balkanization which reigned by 2004/5 be assigned to the presence among the philosophy faculty of just 1697 more members—an average growth of about 57 people per year? Or is it reasonable to suspect that other factors might be in play?
