My Ph.D. dissertation, completed in 1971, showed how one could develop a scientific theology. Following Henry Nelson Wieman, I offered an operational definition of “God” as “creative process.” I then showed how one could develop and test experimentally ideas about the conditions and structure of the creative process, that is ideas about God. I know this sounds strange, but it did earn me my Ph.D.
