In this engaging study Professor Clark sets out to show that there are good philosophical reasons for theism, and Christian theism in particular. He travels the breadth of our intellectual engagement with the world, from ethics to scientific knowledge, and his journey is vigorously argued, fresh, lively and readable. He explores the assumptions which underpin our philosophical and everyday thinking alike, examines the construction of the arguments used to support them, and tests the sturdiness and the makeup of their props and foundations.
