Tawney argues rightly that there is an interaction between religion and the social/economical circumstances because 'it seems a little artificial to talk as though capitalist enterprise could not appear till religious changes had produced a capitalist spirit. It would be equally true, and equally one-sided, to say that the religious changes were purely the result of economic movements.' (p. 312)
As a matter of fact, the Christian Church itself had changed mightily in the Renaissance. It persecuted the Spiritual Franciscans who followed St Francis' rule of evangelical poverty! It was the richest company in the Western world (see 'A world lit by fire' by W. Manchester).
Tawney remarks rightly that what Calvin did for the bourgeoisie of the sixteenth century, Marx did for the proletariat of the nineteenth.
Calvin's success was firmly prepared by Puritan moralists, who stressed thrift, work as an end in itself, efficiency and rational calculation. They paved the way for a shrewd commercial and powerful middle class, which adopted the Calvinist religion and its ethic as a natural ally.
This very rich book shows the real impact of Calvinism on the whole society. One example: wages. Calvinism considered 'that high wages are not a blessing, but a misfortune, since they merely conduce to weekly debauches.' (p.267)
This is a brilliantly written, colourful, metaphorical, and yet scientific work. It should be an example for all historians and should show them how to present important historical evolutions in a comprehensive and attractive language.
This is an essential read for the understanding of our own modern society.
I would recomend this book to anyone studying polisci, history, sociology and even theology, to give a good perspective on why we think the way we do. Our western mindset is a classic example of not seeing the forest throught the trees.
