Bernard J.F. Lonergan presented a contemporary argument for the existence of God in his important work insight: A Study of Human Understanding. The argument proceeds from his cognitional theory and epistemology and took the following general form:
If the real is completely intelligible, then God exists.
But the real is completely intelligible.
Therefore, God exists.
Fr. Spitzer has reworked this argument so that it begins with ontological premises, but arrives at the same conclusion, namely, that a unique, unrestrictedly intelligible reality (i.e. an unrestricted act of understanding) exists, and that this reality is the ground of the intelligibility and reality of all else that is. This proof is systematically presented in Fr. Spitzer’s new book: New Proofs for the Existence of God: Contributions of Contemporary Physics and Philosophy which will be published by Eerdmans in early 2010.
BIO: Father Robert Spitzer, S.J., was President of Gonzaga University from 1998 to July 2009. He has authored five books, many scholarly articles, and journal pieces. He speaks widely to national and international audiences, has started seven academic centers, and is involved in a variety of different educational, philosophical, and scientific organizations.
Fr. Spitzer has had a long-standing interest in metaphysics, the ontology of physics, and their relationship to faith. His doctoral dissertation (entitled, A Study of Objectively Real Time – Director: Paul Weiss, reprints through University Microfilms International, Ann Arbor, Michigan) is concerned with the fundamental nature and underlying conditions of temporality. He connects this ontology of time to the special and general theories of relativity.
