\section{Bayesian Inference}  One very natural way of representing beliefs $b$ and $\phi$ mathematically is as subjective probability functions. In this case, we may restrict our theories of rationality to those which are consistent with Bayesian inference.  Assume that a belief $b$ actually corresponds to a probability function $\mathbb{B}$ representing a belief about the instantaneous state $Z_t$ of a ``phenomenal world'' variable $Z$, and how the world's next state $Z_{t+1}$ is co-distributed with instantaneous action $a_t$ and sensation $s_{t+1}$.  \[ \mathbb{B} : (Z \times Z \times A \times S) \to \mathbb{R} \]
