Comment on The Born Probabilities

Hm, Wei_Dai(2009) seems to have a notion of rationality that is quite permissive if he's convinced by Finkelstein. If rationality isn't in fact permissive and instead stringently requires diachronic consistency (exceptionlessness, updatelessness, pre-rational priors) then I don't think Finkelstein's arguments are convincing. And there are positive arguments, e.g. by Derek Parfit, that rationality is normatively "thick".
