Autonomy All the Way Down: Systems and Dynamics in Quantum Bayesianism

Quantum Bayesianism (QBism) has been put forward as an approach to quantum theory that avoids foundational problems by altogether disavowing the objective existence of quantum states. It is shown that QBism suffers its own versions of the familiar foundational problems, and that these QBist versions are illuminating not just for QBism, but for more traditional foundational approaches as well.
