In over 150 entries, this dictionary covers technical terms which Wittgenstein introduced into the philosophical debate or transformed substantially (state of affairs, picture-theory of proposition, object, language-game, criteria, form of life) and also topics which play a central role in his work (understanding, thinking, mathematical proof); it indicates his line of argument, its strength and problems; and sheds light on fundamental exegetical and substantial controversies. The dictionary also - in addition to a short biographical sketch and the entries themselves - contains a short essay attempting to identify and link the basic themes of the early and later philosophy. It focuses on the idea that Wittgenstein's master-problem was the attempt to clarify the nature of philosphy itself and to introduce and demonstrate a new philosophical method.
