| Dec 16, 2014 at 21:33 | comment | added | Mark Mitchison | Do you know what a Poisson bracket is? The operator representation of variables with a classical limit are found by demanding that their commutator is given by $i\hbar$ times the classical Poisson bracket. Spin operators can be derived by self-consistency arguments and some minimal physical input, see Dirac's Principles of Quantum Mechanics. | |
