We assume the standard decoherent (or consistent) histories formulation of quantum mechanics for closed systems. Notions of environment and records emerge automatically from a specification of the coarse graining, not as separate postulates of quantum mechanics. Anthropic reasoning is also automatic for probabilties for observations.

A striking feature of our quantum universe is the wide range of time, place, and scale on which the laws of classical physics hold to an excellent approximation. Such a realm of classical predictability does not emerge generally in any quantum universe but is a consequence of the specific quantum state of ours. We sketch the origin of the quasiclassical realm stressing the importance of classical spacetime. In particular we show how the variables of classical physics are singled out.

We describe a program of finding a complexity based measure of classicality on sets of decoherent histories in variables other than the usual classical ones. That could help answer the question of whether the classical realm is unique in its high level of predictability, simplicity, and interest.
