Classical perception follows solely from the linearity of quantum mechanics with no need for decoherence or the environment
Abstract
As illustrated by Schrodingers cat, there are often several macroscopically different versions of reality simultaneously existing in the wave function. On the face of it, this would seem to imply that an observer could perceive a superposition of versions and thereby put quantum mechanics at odds with our perceptions. However one can show, without invoking decoherence or the environment, that the linearity of quantum mechanics implies we will perceive only a single, classical version of reality. Linearity also implies our perceptions will have a particle-like consistency.

Version 3, 12 pages July 2015. Makes extensive use of the linear time evolution of the states and explores more fully the way perception of the state vectors imitates a universe made of particles.Version 4, 10 pages, arguments made clearer
