The book of the Buddhist monk Matthieu Ricard scientific training is undoubtedly one of the largest I've read over the last ten years in French and sciences of man and society. It focuses on a key question: empathy. I am interested in this concept a long time ago, in the 1970s, after exploring the epistolary colloquium on René Zazzo attachment. Matthieu Ricard in 2013 gives us a synthesis research on the latest work, including experimental psychology on this topic in the United States of America, Canada, England and Europe, especially in Germany. The interest of the dense and supplied book (over 900 pages) Matthieu Ricard is its multidisciplinary bias. It uses cognitive resources and scientific research in both psychology and sociology, anthropology, spirituality, neurosciences etc. But he does not forget to give his point of view ethics, from his world so close to the Dalai Lama which he is the French interpreter. The only critical thing I can do is too fast in his commentary on the Freudian psychoanalysis and especially Carl Gustav Jung (few lines). Working on yourself and the human relationship in psychoanalytic treatment is probably more complex than the interpreter. This does not, of course, to denounce the shortcomings and biases sometimes outrageous and sometimes dishonest of Freud and his followers.
