We live in a situation of environmental catastrophe, crime, bankruptcy of values, hedonistic materialism, and there is no prospect of salvation. Despair leads man to search with anguish for some guideline to assimilate this disconcerting reality. The author of the book, from a philosophical perspective, offers us an interpretation of the background of this existential drama experienced by man. The book is seductive for its critical and polemical character, for the simplicity and clarity of its style, and for the frankness with which the author sets out his postulates.
