A new edition of the Philosophical Gourmet Report, what has become the authoritative ranking of graduate programs in philosophy in the English-speaking world, will be out this Fall and it's fair to say that the heirarchy will certainly change. The present rankings are almost two years old and the new ones will no doubt reflect the many faculty changes that have taken place since then within departments all over the United States and beyond.
As Brian Leiter has remarked, my own department, the University of Texas, has improved dramatically since the last rankings were published. The very recent appointments of eminent philosophers Jonathan Dancy and George Bealer, with other senior appointments to follow, have arguably put it among the top 10 departments in the country.
And in fact there is a strong argument to be made for this. To start with, Texas is well represented in the world of academic journals; we have one of the past editors of the most prestigious philosophical journal in the world, Mind (Mark Sainsbury), the current editor of the leading journal in moral and political philosophy Ethics (John Deigh), and the current editor of a leading journal in ancient Greek philosophy and science, Aperion (Jim Hankinson).
The department's reputation as an international center for the study of ancient Greek philosophy is over thirty years old; we have one of the world's leading authorities on the Pre-Socratic philosophers (Alex Mourelatos), an internationally known translator and scholar of Plato (Paul Woodruff), and leading scholars of Aristotle, the Skeptics, and the Stoics (Jim Hankinson, Steve White). And coverage in the history of philosophy does not stop there: UT has possibly the most distinguished Hobbes scholar in North America (Al Martinich), a number of excellent historians of twentieth century analytic philosophy (Ed Allaire, Herb Hochberg, Mark Sainsbury), and possibly the world's authority on Existentialist philosophy (Robert C. Solomon). Texas is also probably the best place in the world to study Nietzsche (see Leiter's informative discussion of this.)
But Texas is far from a department entrenched in history: we have developed into a center for research in logic and the philosophy of language (Nicolas Asher, Rob Koons, Al Martinich, David Sosa, Dan Bonevac, Mark Sainsbury...) as well as the philosophy of mind (Michael Tye, who is one of the leading philosophers of mind at the moment, David Sosa, George Bealer, and now Adam Pautz, a recent student of Ned Block and recent junior hire). We are gaining increasing notoriety as a place for studying moral, legal, and political philosophy (John Deigh, Jonathan Dancy, Robert Kane, Sosa, and Brian Leiter). Also, don't forget the rise to prominence of the Law and Philosophy Program (see Leiter's post on this) and our strengths in philosophy of science (Sahotra Sarkar, Cory Juhl, Jim Hankinson, Bob Causey).
As if the foregoing isn't reason enough to count Texas among the very best programs in the world, another reason is that many of those departments which outranked Texas two years ago have lost or will lose some of their most distinguished faculty. UC-Berkeley has lost Donald Davidson, Richard Wollheim, and Bernard Williams, three towering figures who are not easily replaceable (to say the least); Arizona may lose David Chalmers to a long-term stay in Australia; and Notre Dame has remained basically the same over the last few years while Texas has only improved.
So I think the bottom line is that Texas Philosophy is engaged in a kind of upward mobility we rarely see of graduate programs, in any discipline (the last time this happened in philosophy was probably about 15 years ago when NYU decided to buy up a bunch of world-class philosophers and instantly became a top-5 department.) It will be exciting to see the advances the department makes in the next two years, as the past two have been extraordinary. Viva Tejas!
