In a world where science seems to prevail over God, millions of people continue to seek an answer to the mystery of existence through faith. Why do we keep believing? What deep-seated need sustains religious sentiment today? With the clarity and sensitivity that have made him one of the most influential voices in contemporary thought, Boris Cyrulnik explores the psychological, emotional, and cultural roots of the religious experience. The author reveals how the concept of God can emerge from early experiences of protection and love, fostered by childhood attachment figures. Thus, God becomes an extension of parental love and a powerful source of meaning and resilience in the face of pain, loss, and uncertainty--though the author also warns that when spirituality ceases to be a refuge and transforms into dogma, it gives rise to the risk of fundamentalism and the rejection of the "other".
