David Lewis was one of the most systematic and influential philosophers of the latter half of the 20th century. His work spans an enormous range of core topics, including metaphysics, philosophy of language, logic, epistemology, philosophy of science, philosophy of mind, ethics, and aesthetics. This volume provides insight into the underlying themes and complex interconnections woven through Lewis’s work, with essays focusing on virtually all of the main themes in Lewis’s work.

In this addition to the highly regarded Companions to Philosophy series, two of the foremost Lewis scholars bring together top philosophers from diverse fields to explain, discuss, and critically extend Lewis’s work in original ways. Each chapter sets the stage for the reader, introducing the subject at hand and explaining Lewis’s treatment of the issues, while including original philosophical engagements with Lewis’s ideas. Those working in and studying the areas in which Lewis made substantial contributions will find this volume an invaluable resource.
