+Bayesian inference is not merely a static updating rule. It is a dynamical system that operates in belief space — the space of all possible probability distributions over hypotheses.

+In dynamical systems terms, the posterior distribution is the state of the system, and the likelihood function is the vector field that drives the system's evolution. The prior distribution sets the initial condition. The question of whether Bayesian inference converges to the truth is then a question about the stability properties of the dynamical system: does the trajectory converge to a fixed point, and is that fixed point the true hypothesis?

+The answer depends on the structure of the hypothesis space. In finite, well-specified models, Bayesian inference is consistent: as the amount of data grows, the posterior concentrates on the true hypothesis. But in infinite or misspecified models, consistency is not guaranteed. The system may converge to a false hypothesis, or it may fail to converge at all. The dynamics of Bayesian inference in complex model spaces are an active area of research in statistics and machine learning.
