  We investigate the idea that different interpretations of quantum mechanics
can be seen as restrictions of the consistent (or decoherent) histories quantum
mechanics of closed systems to particular classes of histories,together with
the approximations and descriptions of these histories that the restrictions
permit. (Talk at the the workshop Quo Vadis Quantum Mechanics, Center for
Frontier Sciences, Temple University, Philadelphia, PA, September 24--27,
2002.)
