Colin Brown's Christianity Western Thought, Volume 1: From the Ancient World to the Age of Enlightenment was widely embraced as a text in philosophy and theology courses around the world. His project was continued with the same spirit, energy and design by Steve Wilkens and Alan Padgett in volume 2, which explores the main intellectual streams of the nineteenth century. This, the third and final volume, also by Wilkens and Padgett, examines philosophers, ideas and movements in the twentieth century and how they have influenced Christian thought.
