Edgar Arthur Singer, Jr. (1898-1958) was an influential American philosopher and one of the founders of empirical idealism. This volume collects some of his most important essays and lectures, including the landmark work 'Mind as Behavior'. With incisive analysis and rigorous argumentation, Singer advances a materialist theory of mind that challenges traditional dualism and idealism. This book is a seminal text in the philosophy of mind and a must-read for anyone interested in the intersections of science and philosophy.
