First published in 1931, this is an attempt by the great economist J. A. Hobson to analyse the relations between economics and religion. After considering the origins of the conflicts and compromises between God and Mammon in the life of primitive man, the author concerns himself primarily with medieval and modern Christianity and the business climate and ethos corresponding with these periods. In particular he focuses upon Catholicism and Protestantism, before considering the attitude of the church towards modern economic movements.
