Maybe, just maybe, this has something to do with the fact that Plato himself was no less the historical and cultural embodiment of The Gap and Rummy's Rule.What reasons might be given in support of epistemic nihilism?...First, the concept (and therefore the thing) has resisted adequate definition for over 2,000 years, ever since Plato raised the question.
Knowledge...proper? And what knowledge is improper in a world where all knowledge is suspect?We all know that true justified belief fails to add up to knowledge proper (Russell, Gettier). Even now we cannot say what knowledge is, despite our best efforts.
Knowledge: the word.The nihilist takes this to show that knowledge is nothing definable: the reason it can’t be defined is that it has no reality to be defined. No one is ever in such a state (even when the skeptic has been silenced).
Back again to the part where some insist that until a word is properly defined there's no point in taking any discussions of it down out of the technical realm. So, sure, if some claim to know that knowledge can't be defined then they can claim to know further that it doesn't exist.
Or something like that?
And then one day The Big One smashes into Earth for that final extinction event. And anything and everything about knowledge is then obliterated along with us. And if we are the only intelligent life form in the universe, it will be as though knowledge never existed at all.Second, there are deep puzzles about knowledge, also ancient: we can’t say how a priori knowledge is possible, and there are problems about the nature of empirical knowledge.
Or something like that?
