in Aristote au Mont-Saint-Michel, Sylvain Gouguenheim purports to refute what he calls a vulgate: the role of Arabs in shaping Latin Europe. She received Greek thoughts from Eastern Christians and then Greek-Latin translators. This book brings the medievists to question the historical method and ethics of historians, taking different points of view: history of philosophy and science, social history, codicology (Jacques de Venice)... Aristote is a remarkable connorer of Aristotle; AVICENNE has achieved a decisive metaphysical breakthrough through the distinction between petrol and existence; in mathematics and physical sciences, the creativity of Arabic authors is indisputable for specialists. As for the role of intermediary given to Mont-Saint-Michel, this is a fable role: Gouguenheim ignores the production and circulation of manuscriptions.When a prestigious publisher published such a book, the medievists wonder about the training and dissemination of their knowledge: they whose research is publicly funded must be heard as soon as one of their divagues.This book introduces rationality and serenity into intercultural debates. It is addressed to those interested in the dialogue of cultures, to secondary school teachers who have been in charge of teaching on this topic and who have been disconcerted.
