  A new interpretation of quantum mechanics, similar to the Copenhagen
interpretation, is developed from time-symmetry arguments and commonly held
principles concerning time and causality. These principles, which are grounded
in ideas outside of quantum mechanics, suggest that the strange features and
paradoxes of quantum mechanics come from backward causation, in which future
events can change the past. Using these principles this paper gives a better
understanding of (and reasons for) stationary states, tunneling, wave-particle
duality, the measurement problem with the collapse of the state vector, Hardy's
paradox, non-locality, and the EPR paradox. These are only a few of the
interpretational successes, and the model will be contrasted to other popular
and/or recent interpretations. Unfortunately, this model is metaphysical,
without any predictive power.
