Abstract
This article reviews the causal exclusion argument and confronts it with some recently proposed refutations based on the interventionist account of causation. I first show that there are several technical and interpretative difficulties in applying the interventionist account to the exclusion issue. Different ways of accommodating the two to one another are considered and all are shown to leave the issue without a fully satisfactory resolution. Lastly, I argue that, on the most consistent construal, the interventionist approach can provide grounds for thinking that higher-level causal notions are as legitimate as lower-level causal notions, but it does not provide grounds for postulating inter-level causal interactions
