Ludwig Wittgenstein is one of the most important philosophers of the 20th century and particularly important is his contribution in the field of logic and philosophy of languages. The paper will analyse Wittgenstein s early phase, which is characterized by so called logical atomism and his late phase, which is valid for linguistic meanings to be formed by the specific use of a language that depends on the “rules” of the use of a language community. The key piece related to the analysis of Wittgenstein's earl y phase is his capital piece Trac t atus Logico Philosophicus . Logic is the main reference point in his understanding of the world and represents the corelation between language, thought and reality. Also important is the pragmatic character of the tractat in terms of language limitation, what we can say and when as well as why we should remain silent. Furthermore, Wittgenstein's late stage is determined by a trivial understanding of language that is so called philosophy of ordinary language . In this respect, Wittgenstein defines the meaning of the language depending on the specific use and compliance with the rules of language games . The key work that marked his late stage of creation was Philosophical Investigations . It introduces new concepts and replaces logic with grammar, which expresses the essence of objects in the world.
