n the face of a world crisis, which is manifestly deeper than one can imagine, many are inclined to ask: "Has Christianity failed?" Fulton Sheen's Thinking Life Through seeks to answer this critical question. The conclusions the author proposes are far-reaching and touch upon subjects as diverse as the truth and meaning of human sexuality, the purpose of life, discordant marriages, angels, alcoholism, the vocation of the soldier, materialism, parenting, and even the question of spanking children.    On the critical subject of freedom, Sheen writes, "The true definition of freedom is the right to do whatever one ought, and oughtness implies law, goals, purposes, and perfection. Freedom is a moral power and not a physical one. It revolves around what man is rather than what man does. We are more free within the law than outside of it."   Thinking Life Through also addresses the world's political climate, something that in many ways mirrors the present political discourse. Focusing on the tragic decline of post-Christian society, Sheen gives special attention to both the threat of communism and the dangers of socialism. Sheen also gives clarity to the role of the individual and the family while living in a time of moral and political uncertainty. Finally, Sheen addresses good manners and politeness as he states in his quintessential style, "Another effect of materialism is to be seen in the decline of courtesy. There is politeness and decorum and a desire to please others when it is generally recognized that every person bears within himself an image of the Divine." For anyone seeking to grow in wisdom, Thinking Life Through will be your guide.
