Faced with the major challenges facing the world's societies in the future, Spiritism can shed a particular light on a new vision that brings spirituality into play. There are, of course, many humanist struggles which, from an ethical point of view, are no different from Spiritist options, and this is where all people of goodwill come together, whatever their philosophical convictions. The laws revealed by the spirit world are natural principles emanating from a transcendent power of creation and infinite love. The existence of God explains the facts of life, the continuity of the spirit beyond death and the intellectual and moral evolution of the soul through the law of reincarnation. On this basis, it becomes possible to approach the major issues of civilisation and society in a way that is not based on the arguments of philosophical materialism. This is what is explored in this book, in the light of messages from the beyond and based on a reflection that takes into account the major principles of spiritualist philosophy. The co-authors of this book are the representatives and leaders of three branches of the Cercle Spirite Allan Kardec, Colombe Jacquin in Lyon, Jacques Peccatte in Paris and Luc Gruntz in Belfort.
