Naive Modus Ponens
In his [2011], Lionel Shapiro proposes a very interesting deflationist conception of logical consequence, according to which the logical-consequence predicate applying to sentences serves as a merely expressive device allowing us to talk in a generalising way about typically non-linguistic entailment facts (just as, according to a deflationist conception of truth, the truth predicate applying t...
متن کاملInstability, Modus Ponens and Uncertainty of Deduction
Considering the instability of nonlinear dynamics, the deductive inference rule Modus ponens itself is not enough to guarantee the validness of reasoning sequence in the real physical world, and from similar cause cannot gain similar result. Some kind of stability hypothesis should be added in order to draw meaningful conclusion. So the uncertainty of deductive inference appears the same as tha...
متن کاملAre Some Modus Ponens Arguments Deductively Invalid?
This article concerns the structure of defeasible arguments like: 'if Bob has red spots, Bob has the measles; Bob has red spots; therefore Bob has the measles.' The issue is whether such arguments have the form of modus ponens or not. Either way there is a problem. If they don't have the form of modus ponens, the common opinion to the contrary taught in leading logic textbooks is wrong. But if ...
متن کاملGeneralized Modus Ponens Using Fodor's Implication and a Parametric T-norm
Using Generalized Modus Ponens reasoning, we examine the values of the inferred conclusion by using Fodor's implication in order to interpret a fuzzy if-then rule with a single input single output and the tnorm ( ) ( )( ) ( xy y x max y , x t ) λ λ − − + + = 1 1 , 1 − ≥ λ , for composition operation. This t-norm is important to use because for 1 − = λ and 0 = λ it gives the commonly used t-norm...
متن کاملOn generalized modus ponens with multiple rules and a residuated implication
We consider a multiple-rule, generalized modus ponens inference scheme, with an interpretation based on compositional rule of inference (CRI) and a residuated implication. We show that such a system is equivalent, as far as CRI is concerned, to a system that satis5es the “basic requirement for fuzzy reasoning”, proposed by Turksen and Tian (Fuzzy Sets and Systems 58 (1993) 3–40). We establish a...
