  The Debunker, by contrast, rejects the idea that one of the many argument forms \(\refp{firefighter}\) instantiates should be privileged as the logical form of \(\refp{firefighter}\). On the Debunker’s view, counterexamples never show anything about a particular argument. All they show is that a form is invalid (that is, that it has invalid instances). To show that a particular argument is invalid, one sort of Debunker holds, one needs to describe a possible situation in which the premises would be true and the conclusion false, and to give a formal counterexample is not to do that.
