There is a saying that I like: "even a stopped clock is right twice a day". Now this is usually used as a bit of a mean joke when someone gets something right when you might not expect them to. However, we can use this as an example of a 'Gettier Case' (I think it is probably my favourite one). As I alluded to at the end of the last post, Edmund Gettier was a philosopher who demolished the classical definition of knowledge (Justified true belief) with a concise paper consisting of a few examples where there is a belief that is true and justified but is quite clearly not knowledge. Why is this important? Well his observation, demonstrated through his examples, made it quite clear that we don’t really have a great way of describing why one thing would count as knowledge, and another thing would just count as fluke, or a lucky chain of events. This is an issue that can impact significantly on how confident we can be in some of the things that we ‘know’. Let’s delve a bit deeper.
