n.
Type of mind-body dualism that maintains that apparent interactions between mental and physical events are in reality the result of God's constant causal action.
Starting from Descartes's mind-body dualism , the occasionalists, whose most prominent exponents were Nicolas de Malebranche and Arnold Geulincx , drew the conclusions that there can be no interaction between mind and body, and that all causality is immanent, within one order or the other, and any appearance of mind affecting body or of body affecting mind must be explained as the result of a special intervention by God, who, on the occasion of changes in one substance, produces corresponding changes in the other.
