How companies form? Why do they compete? These conflicts can be avoided? Morality and religion are they only make life possible in society, or do they permit humans to exceed its natural condition and to find a solution to the violence? These are some of the questions at the heart of the Two Sources of Morality and Religion (1932), the sum of moral and political philosophy of Bergson, who was also his last great livre.Dans this text haunted by the specter of war and the development of technology, but also guided by a meditation on Christian mysticism, Bergson articulates the study of society in his philosophy of vie.Mettant his doctrine to the test, he strives to make principles of action for men become aware of the need to confront their common destiny. And while "humanity groaning, half crushed under the weight of the progress it has made," he reminds us that the future depends on it. Cover illustration: © Flammarion Virginia Berthemet
