 God has arranged matters, in human nature, so that certain thoughts in the mind are accompanied by changes in the brain, and certain motions of animal spirits trigger specific thoughts in the mind. God’s creative arrangement by which these twinned realities interact provides the ultimate explanation (if it is such) of a familiar fact of our experience. In that sense, the role of God in relation to mind-body interaction is exactly similar to God’s role in relation to body-body interactions.
