 First, one may hold that it is not a problem for our notion of backward causation that we can in principle intervene in the course of the events. Usually, we find out whether two events are causally connected trough manipulation and intervention. In case we can produce one event \(Q\) by bringing about another \(P\), or we can obstruct one event \(Q\) by preventing another \(P\), we think that \(P\) is the cause of (\(Q\). Likewise, we believe that if \(P\) causes \(Q\) in the relevant circumstances, we may be able to prevent \(Q\) from happening if we intervene in the causal order after \(P\) occurs by changing some of these circumstances, which make \(P\) causing \(Q\). Should \(Q\) occurs in spite of this intervention, there must under the new circumstances be another event \(X\) rather than \(P\) that causes \(Q\).
