What value does philosophizing and the art of teaching it hold? This anthology attempts to provide a comprehensive answer: the first part presents classical reflections on the topic from texts by, among others, Plato, Kant, Nietzsche, and Russell. The second part gathers studies specifically written for this volume by renowned experts, such as Ekkehard Martens' "Why Philosophize in School?", Holm Tetens' "Teaching Argumentation", Dieter Birnbacher's "School of Independent Thinking - the Socratic Dialogue", and Johannes Rohbeck's "Methods of Philosophy Teaching". In this way, it becomes an indispensable resource for any form of teaching philosophy, whether in schools, universities, or adult education.
