Abstract

The thesis of this paper is that the Tractatus and the Investigations can be related as follows. Wittgenstein attempted in the Tractatus to avoid the conceptual realism of Frege and Russell with respect to propositions. He solved his problem by developing the picture-theory of language. This solution assumed that the units of language are words which arc names of simple objects. Because of this assumption the solution has the undesirable consequence that examples oi genuine names, atomic facts and atomic propositions cannot be given although their existence is logically required by the solution. Wittgenstein had, therefore, eventually to examine the idea of a name. Thus the Philosophical Investigations in which this examination is conducted.
