The Varieties of Religious Experience oleh William James

The psychology of religious belief. "If the inquiry be psychological, not religious institutions, but rather religious feelings and religious impulses must be its subject, and I must confine myself to those more developed subjective phenomena recorded in literature produced by articulate and fully self-conscious men, in works of piety and autobiography." According to Wikipedia: "William James (1842 – 1910) was a pioneering American psychologist and philosopher trained as a medical doctor. He wrote influential books on the young science of psychology, educational psychology, psychology of religious experience and mysticism, and the philosophy of pragmatism. He was the brother of novelist Henry James and of diarist Alice James. William James was born at the Astor House in New York City. He was the son of Henry James Sr., an independently wealthy and notoriously eccentric Swedenborgian theologian well acquainted with the literary and intellectual elites of his day. The intellectual brilliance of the James family milieu and the remarkable epistolary talents of several of its members have made them a subject of continuing interest to historians, biographers, and critics."
