Epistemology: The Paradox of the Ravens
Published on Jul 24, 2015
In this video, Marc Lange (UNC-Chapel Hill) introduces the paradox of confirmation, one that arises from instance confirmation, the equivalence condition, and common inference rules of logic.
This was solved by Popper: You don’t look for confirming evidence. You look for DIS-confirming evidence, and hold your hypothesis tentatively.The use of the word “confirmation” is what’s not sound. Sure, you can apply the evidence; your chair without ballet shoes does indeed lend evidence that all ravens wear ballet shoes. See, that one piece of evidence is in support of all ravens being black, but it isn’t enough evidence to completely confirm it. now if you find every non-black thing and there isn’t a single raven among them: you’ll know that every raven is black.
