Branching and Uncertainty
Following Lewis, it is widely held that branching worlds di¤er in important ways from diverging worlds. There is, however, a simple and natural semantics under which sentences uttered in branching worlds have much the same truth conditions as they do in diverging worlds. Under this semantics, whether branching or diverging, speakers cannot say in advance which branch or world is theirs. They ar...
متن کاملUncertainty, Belief, and Probability
We introduce a new probabilistic approach to dealing with uncertainty, based on the observation that probability theory does not require that every event be assigned a probability. For a nonmeasurable event (one to which we do not assign a probability), we can talk about only the inner measure and outer measure of the event. Thus, the measure of belief in an event can be represented by an inter...
متن کاملUncertainty and Probability
This paper examines the relationship between probability theory and reasoning in uncertainty, and argues that (contra opposing views) probability theory does have a place in reasoning in uncertainty, but that its place is more restricted than many of its advocates claim. Two major theses are argued for. (1) Reasoning from probabilities works well in domains which permit a clear analysis in term...
متن کاملFuzzy and Probability Uncertainty Logics
Probability theory and fuzzy logic have been presented as quite distinct theoretical foundations for reasoning and decision making in situations of uncertainty. This paper establishes a common basis for both forms of logic of uncertainty in which a basic uncertainty logic is defined in terms of a valuation on a lattice of propositions. The (non-truth-functional) connectives for conjunction, dis...
متن کاملNegative Probability and Uncertainty Relations
A concise derivation of all uncertainty relations is given entirely within the context of phase-space quantization, without recourse to operator methods, to the direct use of Weyl’s correspondence, or to marginal distributions of x and p. Phase-space quantization is the third autonomous and logically complete formulation of quantum mechanics beyond the conventional ones based on operators in Hi...
