From this perspective Information, Interaction, and Agency neatly ties together classical themes such as rationality, decision making and belief revision with the game, strategies and learning in multi-agent environment. Unified by the central notion of Information, Interaction, and Agency, the essays in this book provides a refreshing methodological perspective on belief revision, epistemic logic dynamic, von Neumann's game, and the theory of evolution of the game, all of which in turn is an important approach to understanding our own rationality and other agents.
