Book Project: Interactive Rationality. I am working with Eric Pacuit on a book on the theory of rational decision making in interaction. Our aim is to highlight the foundational/philosophical issues that are coming up in contemporary "interactive epistemology," an emerging field at the intersection of game theory, logic, computer science and philosophy.
We will put online the various drafts of the chapters as they are ready. Comments are welcome!

Chapter 1: General Introduction.
Chapter 2: Mutual and higher-order expectations. Models of soft and hard information in interaction, both in qualitative and probabilistic form.
Chapter 3 - 4: Interactive Rationality and the Dynamics of Reasons. Choice rules (dominance, admissibility) and solution concepts (best response and Nash eq.) as normative sources, reasons for actions, and their dynamic behavior. Paper Version
Chapter 5: The Dynamics of Interactive Rationality (paper version). Reasoning to a proper informational context, general categorizations of strategies, overriding and remembering reasons, applications to admissibility.
Chapter 6: Collective rationality.

This is my personal home page. My official page at the Munich Center for Mathematical Philosophy is: http://www.philosophie.uni-muenchen.de/lehreinheiten/logik_sprachphil/personen/olivier_roy/index.html I am not one of these Olivier Roy! I am assistant at the Munich Center for Mathematical Philosophy. Before that I worked for three years as postdoctoral researcher at Rijksuniversiteit Groningen in the Faculty of Philosophy. I have completed by PhD in February 2008 at the Institute for Logic, Language and Computation in Amsterdam, under the supervision of Johan van Benthem (Amsterdam and Stanford) and Martin van Hees (Groningen). I am also associate editor of Erkenntnis, Topoi, Theory and Decision Library Series A, and Section Editor for the "Logic, Computation and Agency" Section of the Stanford Encyclopedia of Philosophy (the latter together with Eric Pacuit and Johan van Benthem).
