Book of apologetics: a collection of questions and answers that young people ask the author about God, the world and men. Each question has a triple structure: it begins with the question and its ramifications; a "But" follows, usually quoting from the Bible, showing that this is not the perspective of faith; and finally the answer to the questions and objections.
Frossard is at home in the world of literature, universal history and ideas, and is familiar with the latest scientific discoveries. This fusion of human culture and a spirit of faith enables him to address doctrinal themes with the ease of the lay thinker. It is precisely this perspective that gives all its flavor and originality to this book. In the answers he gives to the 47 questions collected in this book, we can see the easiness of someone who walks on the firm ground of faith, and how is imbued with a joyful freedom of mind.
