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."
With a new afterword by the author, this classic analysis of Western liberal capitalist society contends that capitalism—and the culture it creates—harbors the seeds of its own downfall by creating a need among successful people for personal gratification—a need that corrodes the work ethic that led to their success in the first place. With the end of the Cold War and the emergence of a new world order, this provocative manifesto is more relevant than ever.
