LTStraipsnyje analizuojama Wittgensteino privačios kalbos problema. Šios problemos užuomazgos įžvelgiamos Platono dialoge „Kratilas“ bei L.Carrollio literatūrinėje kūryboje. Drauge analizuojamas S. Kripke's siūlomas Wittgensteino privačios kalbos argumento nagrinėjimas ir daroma išvada, kad privačios kalbos būti negali. Tai išvada, deranti ir su Platono ironija, ir su groteskišku Carrollio sąmoju. Iš privačios kalbos negalimybės įrodymo plaukia, kad negali būti ir logiškai privataus pasaulio.
ENArticle is centered around the problem of "private language" as presented in Wittgenstein's philosophy. The problem is related to the same problem introduced by Plato and by the work of Lewis Carroll. Therefore the article puts forward a hypotesis about the work of Carroll as an inspiration to late Wittgenstein's work. The article also analyzes the approach of Saul Kripke to the proper understanding of Wittgensein's problem, and draws the conclusion about the impossibility of "private language". This conclusion is in agreement with the irony of Plato and the grotesque wit of Carroll. From the proof of the impossibility of "private language" it follows, that logically "private world" is also impossible.
