The Summa of St. Thomas Aquinas, so important to Catholic thought and philosophy, has been put into straight chapters and modern idiom by Father Farrell, whose elder thinking and excellent style render valuable service to the present-day reader who might find it difficult to read the objection-and-answer form of the original. The three preceding volumes in this series were entitled The Architect of the Universe. The Pursuit of Happiness, and The Fullness of Life. This concluding volume, The of Life states the supernatural facts and traces the royal road a man's feet must walk and the goals that await him at the end of the journey.
