    "abstract": "The space P of pure states of any physical system, classical or quantum, is\nidentified as a Poisson space with a transition probability. The latter is a\nfunction p: PxP -\u003e [0,1]; in addition, a Poisson bracket is defined for\nfunctions on P. These two structures are connected through unitarity. Classical\nand quantum mechanics are each characterized by a simple axiom on the\ntransition probability p. Unitarity then determines the Poisson bracket of\nquantum mechanics up to a multiplicative constant (identified with Planck\u0027s\nconstant). Superselection rules are naturally incorporated.",
