In his magnum opus, Process and Reality, Alfred North Whitehead claims a special affinity to Oxford philosopher Francis Herbert Bradley. McHenry clarifies exactly how much of Whitehead's metaphysics is influenced by and accords with the main principles of Bradley's absolute idealism. He argues that many of Whitehead's doctrines cannot be understood without an adequate understanding of Bradley, in terms of both affinities and contrasts. He evaluates the arguments between them and explores several important connections with William James, Josiah Royce, George Santayana, Bertrand Russell, and Charles Hartshorne.
