I bought this book after reading the glowing review of Roger-Pol Droit in the World. I have not been disappointed. I myself am a vegetarian for many years and I thought well know the subject. But with this book I truly discovered the rich history of vegetarianism. Moreover, Mr. Larue can write: as a teacher, I will definitely use extracts from his book in class. PUF to thank you for giving us a reference book of this quality.
