Abstract
It is known that Wittgenstein enjoyed reading Plato; but the significance the philosopher had for him is quite underrated, and has never been properly understood. Utilizing insights by Ortega and E. Havelock, the paper argues that while the background of Plato's philosophy was the emergence of literacy, the genesis and the direction of Wittgenstein's later philosophy, by contrast, is not independent of the emergence of post-literacy (or "secondary orality", to use Walter J. Ong's term). A post-literal phenomenon clearly having specifc impact on Wittgenstein was the film: it is striking that he regularly used the film metaphor to illustrate philosophical points. Analyzing these metaphors the paper reaches the conclusion that according to Wittgenstein the carrier of uncorrupted meaning is, actually, spoken language; if we leave the rein to written language, philosophical problems will arise
