Joyce's "Main Theorem" is that these axioms imply that if a person's credence function b does not satisfy the laws of probability Joyce's Main Theorem assumes that the set of propositions is countable. In Section 3 I show that Joyce's argument for one of his axioms is Joyce is here claiming that Weak Convexity follows from a premise that and so Joyce's argument for Weak Convexity is invalid. We have seen that Joyce's arguments for Weak Convexity and Symmetry are both unsound. Joyce's first four axioms may be stated as follows. Besides the six axioms, Joyce's argument for probabilism assumes that ./cache/work_rq43ctq6bffcnb3wkpitzamzki.pdf ./txt/work_rq43ctq6bffcnb3wkpitzamzki.txt
