The Principles of Psychology

1890 · 19th Century · Philosophy

The Principles of Psychology is a two-volume, 1,400-page textbook that William James spent twelve years writing for Henry Holt's American Science Series. It sets out to treat psychology as a natural science of mental life, studying feelings, desires, cognitions and decisions together with their bodily conditions, while refusing to reduce the mind to physiology or to dissolve it into atoms of sensation.

The Varieties of Religious Experience

1902 · Early 20th Century · Philosophy

The Varieties of Religious Experience: A Study in Human Nature collects the twenty Gifford Lectures on Natural Religion that William James delivered at the University of Edinburgh in 1901 and 1902. Instead of studying churches, creeds or theology, James studies personal religious experience as a psychologist, drawing on a large collection of first-person documents: diaries, autobiographies, letters and replies to questionnaires.
