If we are to regain a sensitivity to the reality of non-sensory facts, including that of life after death; if we wish to escape some of the problems of dualism while affirming many of dualism’s strengths; if we want to affirm the benefits of a naturalistic view of the origin of mind from matter without rejecting the activity of God in the world or the reality of religious and paranormal phenomena; then Griffin’s model is a strong candidate to plausibly meet these needs. It is the merit of his interpretation of process thought that it rises above the extinctionist interpretation and considers the data of religious life in a non-reductionist manner.
