چکیده
Probabilism is committed to two theses: 1) Opinion comes in degrees—call them degrees of belief, or credences. 2) The degrees of belief of a rational agent obey the probability calculus. Correspondingly, a natural way to argue for probabilism is: i) to give an account of what degrees of belief are,

متن کاملWhat Are Degrees of Belief?
Probabilism is committed to two theses: 1) Opinion comes in degrees—call them degrees of belief, or credences. 2) The degrees of belief of a rational agent obey the probability calculus. Correspondingly, a natural way to argue for probabilism is: i) to give an account of what degrees of belief are, and then ii) to show that those things should be probabilities, on pain of irrationality. Most of...
متن کاملTen claims about fuzzy logic
3. Distinguish between fuzziness as impreciseness (vagueness) and uncertainty as beliefs. The former deals with degrees of truth, the latter with degrees of (un) certainty. The main reason consists in the following: FL may be (and mostly is) truthfunctional; logics of belief are not. FL is a many-valued logic, logic of belief is a kind of modal logic. Caution: non-truth functional FLn is also p...
متن کاملFrom Degrees of Belief to Beliefs: Lessons from Judgment-Aggregation Theory
What is the relationship between degrees of belief and (all-or-nothing) beliefs? Can the latter be expressed as a function of the former, without running into paradoxes? We reassess this “belief-binarization” problem from the perspective of judgmentaggregation theory. Although some similarities between belief binarization and judgment aggregation have been noted before, the literature contains ...
متن کاملA Co-inductive Language and Truth Degrees
We investigate what happens if PA LTr2, a co-inductive language, formalizes itself. We analyze the truth concept in fuzzy logics by formalizing truth degree theory in the framework of truth theories in fuzzy logics. Hájek-Paris-Shepherdson’s paradox [HPS00] involves that so called truth degrees do not represent the degrees of truthhood (defined by the truth predicate) correctly in Lukasiewicz i...
