Like many immigrant kids, Willem A. deVries was born in New York City.  Most of his early childhood was spent in upstate New York, but high school was in Lynchburg, VA.  He took his B.A. from Haverford College, where he worked with Richard J. Bernstein, and his M.A. and Ph.D. from the University of Pittsburgh, where Wilfrid Sellars was his Doktorvater.  He also spend two separate years at the Hegel Archives at the Ruhr Universität Bochum under the auspices of the Fulbright Program.  He has taught at Amherst College, Harvard University, Tufts University, University College Dublin, and the University of Vienna, where he was Fulbright Distinguished Lecturer.  He is a Professor of Philosophy, now Emeritus, at the University of New Hampshire. 

His books include Hegel's Theory of Mental Activity, (Ithaca, NY: Cornell University Press, 1988), Knowledge, Mind, and the Given: A Reading of Sellars’ “Empiricism and the Philosophy of Mind,”   (With Timm Triplett)  (Cambridge, MA:  Hackett Publishing, 2000), Wilfrid Sellars, Philosophy Now Series, (Chesham, Bucks: Acumen Publishing and Montreal & Kingston: McGill-Queen’s University Press, 2005) and Empiricism, Perceptual Knowledge, Normativity and Realism: Essays on Wilfrid Sellars, W. A. deVries, ed. (Oxford: Oxford University Press, 2009). 

His publications have focused principally on G. W. F. Hegel and on Wilfrid Sellars, with occasional forays into other topics.

Starting in 2012, there is a new endeavor occupying me as well:  The Routledge Studies in American Philosophy.  I co-edit this series with Henry Jackman.  We are trying to put out quality books that are either in or about American Philosophy, construed broadly.  "Construed broadly" here means that we do not identify American Philosophy solely with pragmatism, allthough we are certainly very interested in studies in and of pragmatist philosophy.  Americans have done significant work in idealistic philosophy, in new and critical realism, in phenomenology, in neo-scholasticism, and in other philosophical traditions.  We hope to publish high-quailty work across the spectrum of American Philosophy.
