The Realm of Ends: or, Pluralism and Theism contains reprints of the Gifford Lectures that James Ward delivered at the University of St Andrews between 1907 and 1910, though Ward himself considers them to be a sequel to the lecture course he delivered at Aberdeen ten years previously. His aim in this series of lectures is ‘to ascertain what we can know, or reasonably believe, concerning the constitution of the world, interpreted throughout and strictly in terms of Mind’. The series is split into two parts, the first of which argues that the world is best conceived in pluralistic terms, though pluralism is by no means a perfect theoretical system, and the second of which introduces theism as a corrective to the gaps and difficulties inherent in the pluralistic descriptive system.
