    "abstract": "We consider an alternative approach to the foundations of statistical\nmechanics, in which subjective randomness, ensemble-averaging or time-averaging\nare not required. Instead, the universe (i.e. the system together with a\nsufficiently large environment) is in a quantum pure state subject to a global\nconstraint, and thermalisation results from entanglement between system and\nenvironment. We formulate and prove a \"General Canonical Principle\", which\nstates that the system will be thermalised for almost all pure states of the\nuniverse, and provide rigorous quantitative bounds using Levy\u0027s Lemma.",
