Jack Donovan from simple principles to explain what a man, referring to the structure qu'adoptait our ancestors.
No man as women would like, but man as he deals with the most natural way its place in the "clan" to the societal changes of the last century.
The main idea of Jack Donovan is that masculine identity can not be built over women, but compared to other men, in groups, in a clan where the values he holds, in namely the strength, courage, mastery, and honor.
What remains perhaps the most difficult to understand in our society (hence the comments on the aspect of "retrograde" expounded by this book) is that Jack Donovan is not interested in making men "good", but that makes them "men" within the meaning of the first "manly" without wearing any judgment on the moral level.
A book that requires thinking about what is really a man in our societies where the clan structure has disappeared, but where reflexes and archetypes are still present.
I removed one star because of certain passages a bit sanctimonious and agreed on the evils of leisure and television (and some others).
