Abstract. Some argue for materialism claiming that a physical event cannot have a non-physical cause, or by claiming the ‘Principle of Causal Closure’ to be true. This I call a ‘Sweeping Naturalistic Argument’. This article argues against this. It describes what it would be for a material event to have an immaterial cause.
