Title: Justified True Belief: Plato, Gettier and Turing.
Abstract:
We examine the relationship between the justified true belief (JTB) account of knowledge and Plato’s theory about it as expounded in the Theaetetus. Considering Socrates’ remarks in the Theaetetus brings us to some concerns raised by Turing and to Wittgenstein’s famous comment explanations come to an end somewhere. We present two simple technical results which bear on the question. And finally, we look at the pragmatic aspects of knowledge.
