The French title does not accurately reflect the content of this book (in fact composed of two tests), which deals mainly various ethical churches and "cults" Protestant, studied in 1905, which differ in their "ethos". The spirit of capitalism is treated more superficially. The style is very flexible, without the heaviness that can sometimes deplored in this type of work. Numerous examples illustrate the words of the author. Recommend especially to readers who seek to understand the Protestant ethic.
