"As the psalms are a microcosm of the Old Testament, so the Expositions of the Psalms can be seen as a microcosm of Augustinian thought. In the Book of Psalms are to be found the history of the people of Israel, the theology and spirituality of the Old Covenant, and a treasury of human experience expressed in prayer and poetry. So too does the work of expounding the psalms recapitulate and focus the experiences of Augustine's personal life, his theological reflections and his pastoral concerns as Bishop of Hippo."--Publisher's website.

Harvard psychologist and philosopher William James' The Varieties of Religious Experience: A Study in Human Nature explores the nature of religion and, in James' observation, its divorce from science when studied academically. After publication in 1902 it quickly became a canonical text of philosophy and psychology, remaining in print through the entire century. "Scientific theories are organically conditioned just as much as religious emotions are; and if we only knew the facts intimately enough, we should doubtless see 'the liver' determining the dicta of the sturdy atheist as decisively as it does those of the Methodist under conviction anxious about his soul. When it alters in one way the blood that percolates it, we get the Methodist, when in another way, we get the atheist form of mind."
