In this paper, the possibility of private language argument in Tractatus Logico- Philosophicus is analyzed. The concept of ‘language that only I could understand” is connected to solipsism, or the impossibility to understand other people’s way of seeing the world. But all members of the same community are able to communicate using the same language, so this language is a general language, and there is no private language, just a private perception of the world. Contemporary linguistic theories of Chomsky and (...) de Saussure are close to this interpretation of private language. (shrink)
