This volume is a continuation of our series exploring Saint Augustine's influence on later thought, this time bringing the fifth century bishop into dialogue with 19th century philosopher, theologian, social critic, and originator of Existentialism, Soren Kierkegaard. The connections, contrasts, and sometimes surprising similarities of their thought are uncovered and analyzed in topics such as exile and pilgrimage, time and restlessness, inwardness and the church, as well as suffering, evil, and humility. The implications of this analysis are profound and far-reaching for theology, ecclesiology, and ethics.

Canyons chronicles the origins, history, and structure of the world's most breathtaking gorges, from North America's spectacular Grand Canyon to western Australia's exciting Windjana Gorge, where the Leonard River snakes its way through an ancient barrier reef. This book also discusses tectonic activity, undersea canyons, liquid rock, and pinpoints recent scientific studies and modern-day ecological challenges. Full-color and black-and-white photographs and line drawings, a glossary, and listings of resources for further study amplify the text and engage readers in the topic.
