G. K. Chesterton was a self-described pagan at age twelve and totally agnostic by age sixteen. Yet his spiritual journey ultimately led to a personal philosophy of orthodox, biblical Christianity. In 1908, at the age of thirty-five, Chesterton published an account of his experiences. In Orthodoxy, the masterpiece of his brilliant literary career, he applies the concept of correct reasoning to his acceptance of Christian faith. Written in a down-to-earth and familiar style, this book nevertheless presents formal, scholarly arguments. Paradox and contradiction, Chesterton maintains, do not constitute barriers to belief; imagination and intuition are as relevant to the process of thought and understanding as logic and rationality. He defines his insights with thought-provoking analogies, personal anecdotes, and engaging humor, making this century-old book a work of enduring charm and persuasion.
