Is it possible to live without believing in anything? What do words like spirituality, religion or non-believer mean? Are all gods comparable? Would a world without atheists or religions be better? Are there atheistic spiritualities? Is Buddhism a religion? Is indifference as reasonable a perspective as the others? Does the homeland, turned into an altar, replace the gods? Can science give meaning to people's lives? Never before have we lived in a world with so many possibilities to choose between different beliefs and, at the same time, completely lose ourselves in the confusion of terms, approaches and offers of meaning. This book aims to be like a large-scale map to guide us and organize the complexity, a map where some of the most deeply rooted atheist, indifferent, agnostic, religious and spiritual beliefs are drawn, some of the most traveled paths of humanity, highlighting above all what is most typical of each path, but also the points of contact between the most irreconcilable worldviews. The work includes an illustrative anthology of the traces left by these spiritual and philosophical traditions, which sometimes diverge and sometimes intersect and enrich each other in the groping progress of humanity since the dawn of time.
