Originally a lecture given at Harvard as part of the Ingersoll Lecture on Immortality, this small volume is psychologist William James’s updated second edition, which addresses criticisms levied against his original work on the nature of human immortality. James sees the individual soul as part of a greater soul, hidden behind the veil of death. And that greater soul, perhaps God, perhaps an essence that defies description, is eternal. James brings together modern science and mysticism to show his audience that the two are not as incompatible as they might have believed. Spiritual seekers, religious individuals, and even skeptics will find this discussion on the possibility of immortality thought-provoking and electric. American psychologist and philosopher WILLIAM JAMES (1842-1910), brother of novelist Henry James, was a groundbreaking researcher at Harvard University and one of the most popular thinkers of the 19th century. Among his many works are Principles of Psychology (1890) and The Varieties of Religious Experience: A Study in Human Nature (1902).
