But there is causality. The sequence of events in the movie are directly caused by the projector, but they have a causal linkage back to Alice and the part of her environment that is captured in the movie. I see no principled reason to consider only the immediate cause and not refer back further in the chain of causation. > So consciousness can never be ascribed to anything physical, Doesn't your argument imply the opposite? Consciousness can only be ascribed to physical things because consciousness is computation and computation requires causal links and causality if a physical relation.
