David Kaplan's intellectual influence on 20th century analytic philosophy has been transformative. He introduced lasting innovations in the philosophy of language and philosophical logic. Just as important, however, is Kaplan's way of doing philosophy; generous but incisive, his profoundlyinteractive style mentored countless generations of students, many of whom contribute to this volume. This volume collects new, previously unpublished articles on Kaplan, analyzing a broad spectrum of topics ranging from cutting edge linguistics and the philosophy of mathematics, to metaphysics, the foundations of pragmatics, and the theory of communication. With its historical introduction and personal tributes, The Philosophy of David Kaplan also reveals much of Kaplan's life and times, highlighting the key players of analytic philosophy of the last century, and underscoring Kaplan's substantial impact on contemporary philosophy.
