Here is me discussing Wittgenstein's private language argument, Wittgenstein on the standard metre, naturalism, evil, God, and Jeremy Corbyn! Link.
(Published in Faith and Philosophy 2011. Volume 28, Issue 2, April 2011. Stephen Law. Pages 129-151) EVIDENCE, MIRACLES AND THE EXISTENCE OF JESUS Stephen Law Abstract The vast majority of Biblical historians believe there is evidence sufficient to place Jesus’ existence beyond reasonable doubt. Many believe the New Testament documents alone suffice firmly to establish Jesus as an actual, historical figure. I question these views. In particular, I argue (i) that the three most popular criteria by which various non-miraculous New Testament claims made about Jesus are supposedly corroborated are not sufficient, either singly or jointly, to place his existence beyond reasonable doubt, and (ii) that a prima facie plausible principle concerning how evidence should be assessed – a principle I call the contamination principle – entails that, given the large proportion of uncorroborated miracle claims made about Jesus in the New Testament documents, we should, in the absence of indepen

Humans were speaking long before they could write, so it's plausible to suggest that the transition to writing involved a cognitive shift that may have given rise to some of the problems discussed by Wittgenstein. For example, it is arguable that in an oral culture, the idea of 'knowledge' as a set of 'facts' simply didn't exist. 'Knowledge' was inseparable from knowers and their practical expertise. Problems in epistemology about 'knowledge' and 'truth' may not have arisen in oral cultures. So perhaps it isn't 'bewitchment by language' as Wittgenstein puts it, but 'bewitchment by literacy'.
Some researchers have argued that even before orality, language began as sign-language, and this may have also left cognitive artefacts that contributed to philosophical problems. I discussed this possibility in my working paper: http://www.academia.edu/15207149/The_Gestural_Theory_of_Language_Origin_Philosophical_Implications
