 Now, the bilking argument holds that backward causation is impossible because we can always intervene after we have observe that the alleged effect occurs and obstruct the alleged cause from occurring. Since nothing prohibits us from doing this whenever we want, it demonstrates that backward causation does not take place. Indeed, if we actually intervene and prevent \(A\) after \(B\) has occurred, then of course a particular later \(A\) (which does not exist) cannot be the cause of a particular earlier \(B\) (which exists). But in all those cases where nobody actually intervenes, events of the same type as \(A\) may be the cause of events of the same type as \(B\). This situation is not different from what may happen in some cases of forward causation. Assume that \(P\) causes \(Q\) in the relevant circumstances. We may still prevent a particular \(P\) from happening, but at the same time a particular \(Q\) may nevertheless occur because in the given circumstances it is caused by another event than \(P\).
