Defense of the Closure Principle

Despite the efforts of skeptics, there are no counter-examples that are sufficient in proving that the Closure Principle is invalid. This is Jonathan Vogel’s main argument in his paper, Are There Counterexamples to the Closure Principle? Vogel presents an interesting argument against counterexamples like Fred Dretske’s “Zebra Case”. He introduces a set of conditions required for such counterexamples to work, and in doing so, demonstrates why the Zebra Case is not even a genuine counterexample to the Closure Principle. In fact, Vogel’s own examples do a much better job of what the Zebra Case intended to accomplish, and even those fail. Interestingly, what accounts for the failure of both Vogel’s and Dretske’s counterexamples are what Vogel takes to be the main features of the very counterexamples that he presents. Those three main conditions have to do with non-arbitrariness, statistical probability, and abnormality. Vogel demonstrates why these counterexamples are insufficient against the Closure Principle through how these conditions are required to make a case against the principle, and how the skeptic line of questions are insufficient in dealing with the principle directly. What is most notable are the conditions put forth that constitute, what Vogel believes, are the best counterexamples against the Closure Principle. He brilliantly reveals how the epistemic weight of those features hold lightly against the Closure Principle, and heavily against the skeptic’s argument. It is this operation of Vogel’s three conditions that will be explored at length for the purpose of establishing several facts. The first is that Vogel’s three conditions adequately take away the plausibility of Dretske’s Zebra Case, and prove the validity of ... ... middle of paper ... ...ermore, the line of questions that the skeptic constantly appeals to in shown to be logically flawed in their form and through the fact that they violate the three conditions. Finally, when the skeptic attempts to sidestep these defenses by claiming they are irrelevant to what skepticism intends to prove, it is the skeptic’s argument that is shown to be irrelevant instead. This final piece of the puzzle against the skeptic’s stance against the Principle of Closure can only be upheld by Vogel’s three conditions, otherwise, it would undoubtedly lead to further random series of questions by the skeptic’s which serve no real epistemological purpose. This is how, the very conditions that hold up the most genuine counterexamples available to skeptics demonstrates both why their own argument fails and that there are no real counterexamples against the Principle of Closure.
