 The short answer is yes: Huber (2007 and 2020, Chapter 5) proves that obeying the normative constraints of the ranking calculus is a necessary and sufficient condition for maintaining consistency and deductive closure, both synchronically and in the face of new evidence. The latter end is, in turn, a necessary, but insufficient means to attaining the end of always having only true beliefs, and as many thereof as possible. Unlike the Dutch book arguments, this result requires no appeal to pragmatic considerations about betting behavior. Brössel, Eder &amp; Huber (2013) discuss the importance of this result as well as its Bayesian role-model, Joyce’s (1998, 2009) “non-pragmatic” vindication of probabilism.
