Idea of language as sign's system refers to limit existing between language and objective world, and all attempts to understand entity of language have results representation about language as about empty form, nonsensible form. The problem of sense which we have in logic and in philosophy is connected with definition of place where sense exists. These notions will characterise sense's way of existence which will be understood as language's activity. Thus, sense as foundation of language reality derives and proposes itself. It derives itself because sense is connected with predicated core of proposition.
Sense is active subject, setting on foundation language, which tells about itself.
