A Reconstruction of Quantum Mechanics

We show that exactly the same intuitively plausible definitions of state, observable, symmetry, dynamics, and compound systems of the classical Boolean structure of intrinsic properties of systems lead, when applied to the structure of extrinsic, relational quantum properties, to the standard quantum formalism, including the Schrodinger equation and the von Neumann-Luders Projection Rule. This approach is then applied to resolving the paradoxes and difficulties of the orthodox interpretation.
