This book illustrates the program of Logical-Informational Dynamics. Rational agents exploit
the information available in the world in delicate ways adopt a wide range of epistemic
attitudes and in that process constantly change the world itself. Logical-Informational
Dynamics is about logical systems putting such activities at center stage focusing on the
events by which we acquire information and change attitudes. Its contributions show many
current logics of information and change at work often in multi-agent settings where social
behavior is essential and often stressing Johan van Benthem's pioneering work in establishing
this program. However this is not a Festschrift but a rich tapestry for a field with a wealth
of strands of its own. The reader will see the state of the art in such topics as information
update belief change preference learning over time and strategic interaction in games.
Moreover no tight boundary has been enforced and some chapters add more general mathematical
or philosophical foundations or links to current trends in computer science. The theme of this
book lies at the interface of many disciplines. Logic is the main methodology but the various
chapters cross easily between mathematics computer science philosophy linguistics cognitive
and social sciences while also ranging from pure theory to empirical work. Accordingly the
authors of this book represent a wide variety of original thinkers from different research
communities. And their interconnected themes challenge at the same time how we think of logic
philosophy and computation. Thus very much in line with van Benthem's work over many decades
the volume shows how all these disciplines form a natural unity in the perspective of dynamic
logicians (broadly conceived) exploring their new themes today. And at the same time in doing
so it offers a broader conception of logic with a certain grandeur moving its horizons beyond
the traditional study of consequence relations.
