Congratulations, Steffi Lewis! Just out — the announcement about your donating David’s papers to Princeton University Library. The photo was taken in Cambridge, the year that he died, when he received an honorary D. Litt. degree from the University of Cambridge.

“He is widely regarded as one of the most important analytic philosophers of the twentieth century. He made significant contributions to philosophy of mind, philosophical logic, philosophy of language, philosophy of science, philosophy of mathematics, epistemology, and metaphysics. His impact and influence was due not merely to the doctrines he defended, but also to the way he framed the philosophical debates in which he engaged. Lewis’s work continues to be widely discussed and remains a central part of contemporary philosophy.”
