Schlesinger on justified belief and probability
Employing (*) we find that if A is true Pr(A)=Pr(A/A)= 1. Now, whether it is justified for S to believe that A is determined by the probability of A for S (p. 61), in fact by whether Pr(A) is greater than n for some fixed number n lying between 1/2 and 1 (p. 46), so (*) entails that S is justified in believing all and only true propositions. Presumably, if rational, S subscribes to all the beliefs that it is justified for him to believe. To rationally subscribe to a true belief is to have knowledge (ibid.). Assuming George Schlesinger to be a rational person we arrive at the conclusion that he is omniscient.
