The concept of emergence, recently revisited in the debate on the mind-body problem, is comprehensively presented in this book with a historical and systematic approach that is unmatched in the German-speaking world and beyond. No one working in the philosophy of mind can overlook this work. Stephan offers both an invaluable overview of the emergence debate and a clear analysis of its problems and perspectives. He has set the standard against which all future works on this important topic will be measured. Stephan presents a comprehensive, well-organized, well-informed, and up-to-date overview of the development and variations of emergentism. Written in an extremely clear and accessible style, it is not only a valuable source.
