By reason of the author's reputation and the general nature of some of his material, this volume of reflective essays of an apologetical, moral and spiritual nature will probably reach a wider market than just the Catholic reading public. It seems intended principally, however, for lukewarm Catholics, as a forceful reminder, in the present age of materialism and unbelief, that the Christian life is totally at variance, as regards both end and means, with the spirit of the world. A suasive account is given of the reasonability, necessity and unique value of Christian faith and the life of grace, prayer, self-denial and supernatural morality. Appeal is made simultaneously to mind and heart. The demands of a truly Christian life are not softened or interpreted in terms of a psychological panacea. The author's talents for clear, arresting and persuasive exposition are employed here to their full extent. The book is replete with apt comparisons, pointed sayings and concrete examples. Readers accustomed to the author's television talks will be surprised to find in this volume more logic than rhetoric and real depth of thought and feeling. In many places in the present volume, the material and style measure up to those of Ronald Knox or Thomas Merton. The reading of this book could have the effect associated with a good retreat among Catholics, and could do much to persuade the modern reader of any or no creed of the reasonableness and unique meaningfulness of surrendering to Christ as such a conversion is understood in Catholic terms.
