It is a great honor to be a focus for the group of authors assembled here. Though public mirrors seldom reflect self- images, we learn most about people, not only by their own words, but also by the company they keep. But enough said about people, let me turn to the topic. This book is about logical dynamics, a bundle of interests and a program that may not cover my whole work, but that definitely constitutes the largest chunk of what I have done over the last decades. Let me explain what it means to me. You may find what follows ideological, some people prefer context-free theorems—but I need such broader perspectives even for myself, to remind me of why I do the things I do—or even, why I do research at all. The main idea of logical dynamics is the pervasive duality between informa- tion-related actions and their products. Standard logical systems emphasize notions like formula or proof in the sense of static objects that can be viewed or even manipulated externally. But these objects are produced in activities of commu- nicating statements, engaging in reasoning, and many other intellectual skills. Interestingly, our natural language is often ambiguous in this respect between verbs or other activity-related expressions and static nouns. A dance is an activity I can engage in, but also an object that can be produced by dancing—and the same duality holds for many logical terms, like ‘‘statement’’ or ‘‘argument.’’ The idea of logical dynamics is to take this duality seriously, and bring the core logical activities explicitly into formal systems that satisfy the same standards of rigor as the ones that we know and love. This is possible, since activities and events, too, have a formal structure that lends itself to logical analysis. In this way, to borrow a happy phrase, ‘‘logic can be more than it is.’’ Over time, my view of what are logical core activities has evolved from single- agent acts of inference and observation to social scenarios involving more agents, with asking a question, perhaps, as the major instance of a basic logical act. This took some time, since this social turn went against central tenets of my upbringing. ix x Preface by Johan van Benthem Dutch Calvinists like me were raised with the idea that there are two modes of life. The horizontal mode looks at other people and what they think, the vertical one
