A few months ago, I noticed an interesting and telling interaction between a group of academic philosophers. A Facebook friend posted a little note about how one of her students had written to her about having encountered a so-called "Gettier case" i.e., she had acquired a true belief for invalid reasons. In the email, the student described how he/she had been told the 'right time' by a broken clock. The brief discussion that broke out in response to my friend's note featured a comment from someone noting that the broken clock example is originally due to Bertrand Russell. A little later, a participant in the discussion offered the following comment:
Even though the clock case is due to Russell, it's worth noting that "Gettier" cases were present in Nyāya philosophy in India well before Russell, for instance in the work of Gaṅgeśa, circa 1325 CE. The example is of someone inferring that there is fire on a faraway mountain based on the presence of smoke (a standard case of inference in Indian philosophy), but the smoke is actually dust. As it turns out, though, there is a fire on the mountain. See the Tattva-cintā-maṇi or "Jewel of Reflection on the Truth of Epistemology." [links added]
