G.K. Chesterton has been described by both his admirers and even his opponents as the "apostle of common sense" and "one of the happiest, kindest, most brilliant and witty" defenders of Christianity that ever lived. In this book, Chesterton's brilliance as a writer and thinker again shines as he explains his understanding of Catholicism and the Catholic Church, and how her appeal to reason and truth eventually won him over. For Chesterton, a man misses the point of it all unless he acts on two essetials at the heart of conversion. He describes these in his own words: "One is that he believes it to be solid objective truth, which is true whether he likes it or not; and the other is that he seeks liberation from his sins." These two reasons are why Chesterton became a Catholic, and are what he describes in his unique and colorful way in this book.
