Yesterday, while browsing through the Wikipedia page on epistemology I came across the following excerpt:
Edmund Gettier is best known for his 1963 paper entitled “Is Justified True Belief Knowledge?”, which called into question the theory of knowledge that had been dominant among philosophers for thousands of years. This, in turn, called into question the actual value of philosophy if such an obvious and easy counterexample to a major theory could exist without anyone noticing it for thousands of years.
I did not know anything about either Edmund Gettier or the referred paper, but the way this paragraph attacked not only all philosophers but philosophy as a discipline left me infuriated, so without doing much research, I deleted it from the article, stating that “you can easily see many examples of philosophers claiming similar issues”. If I wanted to get into more detail, I would have added that I don’t think that there is such thing as a “dominant theory” in philosophy and especially such that has no counterexamples - philosophy, after all, is about arguments, so you really want to you can always construct arguments to support even the stupidest thesis (which was what I was planning to do if someone attacked me for messing with Wikipedia’s epistemology page).
