The Varieties of Religious Experience

William James

The Varieties of Religious Experience: A Study in Human Nature is a book by Harvard University psychologist and philosopher William James. It comprises his edited Gifford Lectures on natural theology, which were delivered at the University of Edinburgh, Scotland between 1901 and 1902. The lectures concerned the psychological study of individual private religious experiences and mysticism, and used a range of examples to identify commonalities in religious experiences across traditions.
