This was written before Chesterton's conversion to Catholicism (1922). It is a response to a critique of Heretics, and in it Chesterton sets forth his beliefs, which align (maybe to his surprise) with orthodox Christianity.
"This book is meant to be a companion to 'Heretics,' and to put the positive side in addition to the negative. Many critics complained of the book called 'Heretics' because it merely criticized current philosophies without offering any alternative philosophy. This book is an attempt to answer the challenge...It is the purpose of the writer to attempt an explanation, not of whether the Christian Faith can be believed, but of how he personally has come to believe it." - from the Preface.
Gilbert Keith Chesterton (1874-1936), English journalist whose works include nearly all forms of written expression, including essays, novels, short stories, poems, plays, biography, and literary criticism. A Christian thinker, he sounded some of the earliest warnings against the tyranny of the modern state, and lamented the loss of wonder & beauty in modern life.
