  We briefly review a number of major features of the approach to quantum
measurement theory based on environment-induced decoherence of the measuring
apparatus, and summarize our observations in the form of a couple of general
principles that, unlike the wave function collapse hypothesis, emerge as ones
consistent with the unitary Schr\"odinger evolution of wave functions. We
conclude with a few observations of a philosophical nature, to the effect that
that quantum theory does not purport to describe reality but constitutes an
{\it interpretation} of our phenomenal reality within a context -- one where
the Planck scale is not crossed. Beyond the Planck scale, a radically new
interpretation of reality is likely to emerge.
