This collection of essays in honour of Santiago Sia is deeply rooted in the process thought of Charles Hartshorne and A. N. Whitehead. With contributors of the highest distinction, the essays are exercises in the philosophy of religion that are yet genuinely interdisciplinary, contextualizing philosophical thinking in areas that include ethics, theology, science, political theory, and the problem of suffering. They are outstanding examples of how to think with more than the intellect but also with vision and imagination and with a clear sense of the context of all thought in the demands of reality and the immediate world. The book provides a brilliant testimony to the career and commitment of Professor Sia as educator and thinker.
