G. K. Chesterton was one of the giants of early 20th century literature. Although never a professional theologian, he was what one might call a lay theologian. This new and engaging study shows how Chesterton's "theology of wonder" not only acts as a brilliant antidote to the philosophy of nihilism, but also provides us today with that element most lacking in modern thought, namely the astonished sense of gratitude and wonder at the mystery of existence, and the joyous recognition, in particular, at the marvel of being human.
