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.
