Beliefs and a general account for self-referential notions

Abstract: Sometimes one’s adopted beliefs can provide additional evidence that undermines their own rational adoption. Such cases bear a close relationship to the liar paradox. We propose moving to allowing one’s beliefs to be indefinite, and requiring that any definite recommendations are definite. Our account is very general and could apply to a whole range of circular, or self-dependent notions. It bears some similarity to the supervaluational Kripkean fixed-point account of truth and can immediately apply to a whole range of notions by just requiring the specification of a revision notion on the precisifications.
