Andreas Blank earned his Ph.D. in 1998 at the Center for Philosophy and Philosophy of Science at the University of Konstanz. Since then, he has held Visiting Lecturer positions at the Humboldt University of Berlin and the Free University of Berlin. His research interests focus on seventeenth century metaphysics and philosophy of science and on the history of early analytic philosophy. He is the author of a monograph about the logical structure of Leibniz’s metaphysics (Der logische Aufbau von Leibniz’ Metaphysik, Berlin-New York: De Gruyter, 2001), as well as numerous articles on the philosophy of Leibniz and the early Wittgenstein. His current research projects concern the role of the Stoic conception of pneuma in the development of Leibniz’s theory of matter, and the influence of the constructivism in Neo-Kantian philosophy of science on Wittgenstein’s early philosophy of logic.
