- Title
Chancy Modus Ponens.
- Authors
Neth, Sven
- Abstract
Chancy modus ponens is the following inference scheme: ' probably φ ', 'if φ , then ψ', therefore, 'probably ψ ' (Yalcin 2010, Moss 2015). I argue that Chancy modus ponens is invalid in general. I further argue that the invalidity of Chancy modus ponens sheds new light on the alleged counterexample to modus ponens presented by McGee (1985). I close by observing that, although Chancy modus ponens is invalid in general, we can recover a restricted sense in which this scheme of inference is valid.
