Book excerpt: While process philosophers and theologians have written numerous essays on Buddhist-Christian dialogue, few have sought to expand the current Buddhist-Christian dialogue into a "trilogue" by bringing the natural sciences into the discussion as a third partner. This was the topic of Paul O. Ingram's previous book, Buddhist-Christian Dialogue in an Age of Science. The thesis of the present work is that Buddhist-Christian dialogue in all three of its forms - conceptual, social engagement, and interior - are interdependent processes of creative transformation. Ingram appropriates the categories of Whitehead's process metaphysics as a means of clarifying how dialogue is now mutually and creatively transforming both Buddhism and Christianity. Drawing also on the work of theologian John Hicks and philosopher of science Imre Lakatos, Ingram develops an understanding of Buddhist-Christian dialogue in the context of a religious pluralism that is both open and dynamic and methodologically rigorous. Wide-ranging and full of insight, The Process of Buddhist-Christian Dialogue will be invaluable to scholars and students of comparative religion.
