It is argued here that a causal account of the behavior of quantum systems can coherently be given within the context of the Basic interpretation of quantum mechanics of Dirac and von Neumann when extended to include positive-operator-valued measures and to include effects as observables. This account is most naturally provided via the notion of probabilistic causation, in particular, as an extension of von Neumann's conception of mathematical causation in mechanics which was intended to generalize aspects of the Laplacian notion to include quantum mechanics.
