Probability Logic and Logical Probability
Many writers who entertain the use of subjective probability or credal probability for, among other things, the evaluation of expected values of options in decision problems insist that such credal probability judgments should be determined by the agent’s “available evidence” or “available knowledge”. Notable 20 century examples are H. Jeffreys (1921, 1951), J.M. Keynes (1921), R. Carnap (1950,...
متن کاملFuzzy logic and probability
In this paper we deal with a new approach to probabilistic reasoning in a logical frame work. Nearly almost all logics of probabil ity that have been proposed in the litera ture are based on classical two-valued logic. After making clear the differences between fuzzy logic and probability theory, here we propose a fuzzy logic of probability for which completeness results (in a probabilistic ...
متن کاملProbability logic
Introduction Among logicians it is well-known that Leibniz was the first to conceive of a mathematical treatment of logic. Much less known, however, was his insistence that there was need for a new kind of logic that would treat of degrees of probability. Although it isn't clear what Leibniz had in mind for such a logic—understandably, since the subject of probability had just begun in his life...
متن کاملProbability, Modal Logic and Fuzzy Logic
Fuzziness is often regarded as a special form of uncertainty, possibly related to probability but not necessarily reducible to the latter. Indeed, all the mathematical techniques that have been proposed to model fuzziness are substantially different from probabilistic methods, albeit sometimes loosely similar. As shown in this paper, a particular form of fuzzy logic can be derived from probabil...
متن کاملProbability and non-classical logic
Classical tautologies have probability 1. Classical contradictions have probability 0. These familiar features reflect a connection between standard probability theory and classical logic. In contexts in which classical logic is questioned—to deal with the paradoxes of self-reference, or vague propositions, for the purposes of scientific theory or metaphysical anti-realism—we must equally quest...
