The emphasis on God in American psychology of religion generates the problem of explaining divine-versus-natural causality in “spiritual experiences.” Especially “theistic psychology” champions divine involvement. However, its argument exposes a methodological error: to pit popular religious opinions against technical scientific conclusions. Countering such homogenizing “postmodern agnosticism,” Bernard Lonergan explained these two as different modes of thinking: “common sense” and “theory”—which resolves the problem: When theoretical science is matched with theoretical theology, “the God-hypothesis” explains the existence of things whereas science explains (...) their natures; and, barring miracles, God is irrelevant to natural science. A review of the field shows that the problem is pervasive; attention to “miracles”—popularly so-named versus technically—focuses the claims of divine-versus-natural causality; and specifications of the meaning of spiritual, spirituality, science, worldview, and meaning itself offer further clarity. The problem is not naturalism versus theism, but commonsensical versus theoretical thinking. This solution demands “hard” social science. (shrink)
