A wonderful, multidimensional book represents a significant contribution to a paradigm shift, change our society so desperately needs facing the systemic crisis, economic, social, ecological, psychological and spiritual of our time. The author in fact shows how our society is permeated by a whole current Western thought over centuries based on the idea that humans are inherently selfish and that the whole nature is governed by a process of evolution and Selection based on individual competitiveness and the fight for survival philosophy that eventually lead to a valuation of selfishness at the expense of altruism, compassion and brotherhood. Faced with this, Matthieu Ricard -alliant his experience and wisdom Buddhist monk engaged in a practice founded on altruism to scientific rigor acquired in his studies- shows based on numerous scientific studies that this view is wrong and false, and that, without denying the root causes of violence, genocide and cruelty that humans can commit, the profound nature of the human being is goodness and kindness. Moreover, this altruism faculty may be cultivated and made to serve in many sectors of our society, in the areas of education, economy and ecology to build a better world based on the recognition of the interdependence of all beings and phenomena.
