This book is a compilation of economic views on the purpose of life. It follows a unique approach, starting with propositions from diverse fields that act as governing laws of the purpose of life in economics, then guiding the reader through the physical, philosophical, and psychological views of the purpose of life, as economics and economic theories can find their roots in all these areas. The book concludes with the purpose of life presented through economic doctrines (from the pre-classical, to classical, to neo-classical schools of economic thought), through the lens of economic development, and from the perspective of several religious doctrines.
