Abstract | Quantum theory is contextual, but is not the most contextual point in the space of all conceivable theories. A natural question is what physical principles, if any, are responsible for the exact amount of contextuality that we observe in nature. I propose that quantum contextuality may arise from the balance between two desiderata: the requirement that every measurement can be realized from a repeatable and minimally disturbing measurement and the requirement that every state can be generated from a pure state. Both requirements are incarnations of the same overarching principle, namely that empirical observations must be compatible with a deeper level of description characterized by maximal knowledge.
