Abstract:
    The study explores the specifics of silence at Ludwig Wittgenstein. The starting premise is that silence is a manifestation of intentional communication. If silence is intentional, however, quiet is always unintentional. Ludwig Wittgenstein discovers that reflective thinking can be expressed either by language, either by silence. He develops the thesis of linguistic silence: "Whereof one cannot speak, thereof one must be silent." Linguistic silence communication dimensions are explained.
