That's interesting. Jack Donovan does input his historic and research articles in his books, so it's not just based on his uneducated opinions. Though, he has great ideas and lengthy in historic cultural examples. I did mention his previous works, which are in this orders just for reminders: "The Way of Men", "Becoming Barbarians", and this third volume: "A More Complete Beast". I have his latest book, which I will mention later; just don't remember the title right now.
