William James (1842–1910) was an American philosopher and psychologist who taught at Harvard. There he offered the first psychology course in the United States and helped establish pragmatism as a philosophy. In his Gifford Lectures, published as The Varieties of Religious Experience (1902) and held in our library, he studied conversion, saintliness, and mysticism through individual testimonies, asking what religious experience does in a person's life.
