 A second respect in which reliance on the notion of an intervention need not be thought of as introducing a vicious circularity is this: So far, I have been following Menzies and Price in assuming that there is just one causal notion or locution \((A\) causes \(B\), where \(A\) and \(B\) are types of events) that we are trying to analyze. But in fact there are many such notions. For example, among causal notions belonging to the family of so-called type causal notions (i.e., causal claims that relate types of events or variables) there is a distinction to be drawn between what we might call claims about total or net causes and claims about direct causes. Even if the notion of an intervention presupposes some causal notion such as some notion of type causation, it may be that we can use it to characterize other causal notions.
