William James (1842 - 1910) is considered one of the fathers of modern psychology. His The Principles of Psychology was published by Holt in 1890.[1] One of his most famous works is The Varieties of Religious Experience, published in 1902. He was the brother of the author Henry James. He is also known as one of the great three classic American pragmatists.

Often overlooked, radical empiricism is school of thought that is a continuation of James's ideas. Later Jamesian scholars include the liberal theologians Henry Nelson Wieman and Bernard Eugene Meland.
