The Information in Intuitionistic Logic Johan van Benthem Abstract: Issues about information spring up wherever one scratches the surface of logic. Here is a case that raises delicate issues of ‘factual’ versus ‘procedural’ information, or ‘statics’ versus ‘dynamics’. What does *intuitionistic logic*, perhaps the earliest source of informational and procedural thinking in contemporary logic, really tell us about information? How does its view relate to its ‘cousin’ epistemic logic? We discuss connections between intuitionistic models and recent protocol models for dynamic-epistemic logic, as well as more general issues that emerge. This paper will appear in an issue of "Synthese" edited by Luciano Floridi and Sebastian Sequoiah-Grayson, following the First Oxford Workshop in the Philosophy of Information".
