This volume contains G.K. Chesterton's 1908 book, 'Orthodoxy'. Chesterton viewed this book as a companion to his other work, 'Heretics', and it has become a seminal text in Christian apologetics. According to Chesterton, this book's purpose is to 'attempt an explanation, not of whether the Christian faith can be believed, but of how he personally has come to believe it.' The chapters of this book include: 'The Maniac', 'The Suicide of Thought', 'The Ethics of Elfland', 'The Flag of the World',
