Which aspect of occasionalism argues that if a person has an itch, it is God that moves their arm to scratch it?

The aspect of occasionalism that posits that it is God who moves a person’s arm to scratch an itch is best captured by the concept of God-mediated communication. Occasionalism is a philosophical theory that suggests that God is the direct cause of all events in the world, and that what we perceive as cause and effect is actually God intervening in the situation.

In this view, when someone feels an itch, rather than the person’s desire or physical action being the cause of scratching, it is God who directly causes the arm to move. This underscores the belief that all action requires divine intervention; in other words, the person does not act independently but is instead a conduit for God's will. This is crucial to understanding occasionalism, as it places God's role at the center of every human experience or physical action, framing all instances of perceived causality as manifestations of divine will rather than independent occurrences.

Other concepts, such as Divine Providence or Pre-established Harmony, approach the idea of God's influence differently and do not convey the direct and immediate involvement of God in every individual action.
