This article, first published in Russian in 1984 in Sign Systems Studies, introduces the concept of semiosphere and describes its principal attributes. Semiosphere is the semiotic space, outside of which semiosis cannot exist. The ensemble of semiotic formations functionally precedes the singular isolated language and becomes a condition for the existence of the latter. Without the semiosphere, language not only does not function, it does not exist. The division between the core and the periphery is a law of the internal (...) organisation of the semiosphere. There exists boundary between the semiosphere and the non- or extra-semiotic space that surrounds it. The semiotic border is represented by the sum of bilingual translatable “filters”, passing through which the text is translated into another language (or languages), situated outside the given semiosphere. The levels of the semiosphere comprise an inter-connected group of semiospheres, each of them being simultaneously both participant in the dialogue (as part of the semiosphere) and the space of dialogue (the semiosphere as a whole).
