WILLIAM JAMES AS AMERICAN PLATO?

Alfred North Whitehead wrote a letter to Charles Hartshorne in 1936 in which he referred to William James as the American Plato. Especially given Whitehead's admiration of Plato, this was a high compliment to James. What was the basis for this compliment and analogy? In responding to that question beyond the partial and scattered references provided by Whitehead, this article briefly explores the following aspects of the thought of James in relation to Whitehead: the one and the many, the denial of Cartesian dualism, James's background in physiology, refutation of Zeno's paradoxes, religious experience, and other kinships. In the end, the author agrees with Robert Neville that James had seminal ideas which could correctly result in a complimentary analogy with Plato. Therefore, a greater focus on the important thought of James is a needed challenge in contemporary philosophy.
