The presentation of the basic principles of Wittgenstein’s methodology of language research has two objectives. First, his discussion of language and meaning only becomes intelligible in a broader perspective of the assumptions adopted concerning research methodology. Second, the assumption of some propositions in contemporary theories on the categories of use or the notion of rule that involves accepting or rejecting some more general claims on language. On account of the vastness of the material, ambiguity in Wittgenstein’s thought but also the complexity of the issues, means not all the principles of Wittgenstein’s later philosophy will be investigated. Only the contexts (of grammar, use and practice) that are vital from the perspective of philosophical dissertations on language will be presented in three steps.
