Vagueness-Induced Counterexamples to Modus Tollens

Proceedings of the Aristotelian Society, 2020
Abstract I argue that vagueness produces counterexamples to modus tollens. I begin by outlining cases where indicative and counterfactual conditionals (henceforth, natural conditionals) seem intuitively to be determinate even when their antecedents are borderline and their consequents are determinately false.

Fuzzy-Rough Modus Ponens and Modus Tollens as a Basis for Approximate Reasoning

Lecture Notes in Computer Science, 2004
We have proposed a fuzzy rough set approach without using any fuzzy logical connectives to extract gradual decision rules from decision tables. In this paper, we discuss the use of these gradual decision rules within modus ponens and modus tollens inference patterns.

Modus Tollens, Modus Shmollens: Contrapositive reasoning and the pragmatics of negation

Thinking and Reasoning, 2007
The utterance of a negative statement invites the pragmatic inference that some reason exists for the proposition it negates to be true; this pragmatic inference paves the way for the logically unexpected Modus Shmollens inference: “If p then q; not-q; therefore, p.” Experiment 1 shows that a majority of reasoners endorse Modus Shmollens from an ...

Epistemic modals and modus tollens

Philosophical Studies, 2016
Epistemic modals in consequent place of indicative conditionals give rise to apparent counterexamples to Modus Tollens. Familiar assumptions behind familiar truth conditional theories of embedded modality facilitate a prima facie explanation—viz., that the target cases harbor epistemic modal equivocations. However, this sort of explanation goes too far.
