Original sentence: However, long ago, Ian Hacking noted that traditional Dutch book arguments did not specify Bayesian updating---they left open the possiblity that non-Bayesian updating rules could avoid Dutch books.If a bookmaker follows the rules of the Bayesian calculus in the construction of his odds, then a Dutch book cannot be made.In fact, there are non-Bayesian updating rules that also avoid Dutch books (as discussed in the literature on "probability kinematics" following the publication of Richard C.Indeed, non-Bayesian agents have no more need to gamble with Dutch bookies than they have to indulge in other problem gambling.Jeffrey's rule).The additional hypotheses sufficient to specify (uniquely) Bayesian updating are substantial, complicated, and unsatisfactory, according to Bas van Fraassen's Laws and Symmetries.Wald's result also established the Bayesian formalism as a fundamental technique in frequentist statistics
