 There has been considerable discussion recently both about the extent to which fundamental physics is causal and about what interventionist frameworks imply about the status of causal claims in physics. A number of the essays in Price and Corry 2007 (Price 2007; Hitchcock 2007b; Woodward 2007) express varying degrees of skepticism about the applicability of causal notions in portions of physics, in part on the basis of interventionist considerations. By contrast, Frisch (2014) argues vigorously that many physical theories, at least in classical physics, such as classical electromagnetism, make extensive use of causal concepts and that the relevant notion of cause is captured by the interventionist framework and associated technical ideas (such as structural equations and directed graphs). He suggests that writers like Price, Hitchcock, and Woodward underestimate the degree to which interventionist ideas of causation are applicable to such contexts. Of course it is also possible, consistently, with the views of both Frisch and these other writers, that causal notions, understood along possibility constrained interventionist lines, are important in many areas of physics but that there are other physical theories that are not fruitfully interpreted as making causal claims, whether understood along interventionist or other lines. In any case, the question of the scope of interventionist theories and their implications for causal claims in fundamental physics is an important and at present unresolved  issue.[6]
