Abstract We put forth an account for when to believe causal and evidential conditionals. The basic idea is embed a model in agent’s belief state. For the evaluation of conditionals seems be relative beliefs about both particular facts relations. Unlike other attempts using models, we show that ours can rather well not only various but also

This paper presents a new deductive argument for the strict conditional analysis of counterfactual conditionals, as against the dominant variably strict analysis due to Robert Stalnaker (1968) and David Lewis (1973). Counterfactual conditionals belong to a broader linguistic family of counterfactual modals. The argument offered here turns on facts about the logical interaction of counterfactual...

The logic of conditionals (and, especially, of subjunctive or counterfactual conditionals) is a long-standing problem for the theory of common sense reasoning and philosophical logic. In this paper, I explore commonalities between the logical accounts of the conditional involving “closeness” relations over possible worlds and work in the logic of action and change that attempts to characterize ...

A functor is constructed from the category of globular CW-complexes to that of flows. It allows to compare the S-homotopy equivalences (resp. the T-homotopy equivalences) of globular complexes with the S-homotopy equivalences (resp. the T-homotopy equivalences) of flows. Moreover, one proves that this functor induces an equivalence of categories from the localization of the category of globular...

According to some theorists, the strength of a conditional statement is determined solely by the extent to which the conditional’s antecedent is sufficient for its consequent. On this view, the strength of conditionals is independent of the degree to which the antecedent is necessary for the consequent. Data from four experiments reported here demonstrate that when people evaluate conditionals,...

In this paper we propose a hierarchy of games that allows us to make a systematic comparison of process equivalences by characterizing process equivalences as games. The well-known linear/branching time hierarchy of process equivalences can be embedded into the game hierarchy, which not only provides us with a refined analysis of process equivalences, but also offers a guidance to defining inte...

Indicative conditionals—that is, sentences typically, though not exclusively, of the form “If p, (then) q,”—belong to most puzzling phenomena language. One puzzles that has recently attracted attention psychologists reasoning stems from fact on majority accounts indicative conditionals, q” can be true, or at least highly acceptable, even when there is no meaningful connection between p and q. C...
