  Time-symmetric interpretations of quantum theory are often presented as
featuring "retrocausal" effects in addition to the usual forward notion of
causation. This paper examines the ontological implications of certain
timesymmetric theories, and finds that no dynamical notion of causation applies
to them, either forward or backward. It is concluded that such theories
actually describe a static picture, in which the notion of causation is
relegated to a descriptor of static relationships among events. In addition,
these theories lead to an epistemic rather than ontologically referring,
realist view of quantum states.
