Background
David Ray Griffin is a longtime resident of Santa Barbara, California, was a full-time academic from 1973 until April 2004. He is currently a co-director of the Center for Process Studies, and one of the foremost contemporary exponents of process theology, founded on the process philosophies of Alfred North Whitehead and Charles Hartshorne. He is also a leading exponent of theories questioning the Bush Administration's account of the September 11, 2001 attacks.

Griffin grew up in a small town in Oregon, where he was an active participant in his Disciples of Christ church. After deciding to become a minister, Griffin entered Northwest Christian College, but became disenchanted with the conservative-fundamentalist theology that was taught there. While getting his master’s degree in counseling from the University of Oregon, Griffin attended a lecture series delivered by Paul Tillich at the Graduate Theological Union in Berkeley, California. At this time, Griffin made his decision to focus on philosophical theology. He eventually attended the Claremont Graduate University, where Griffin received his Ph.D. in 1970.
