Abstract

This chapter provides an overview of those of Frege's basic contributions to a theory of meaning that are most important for an understanding of Wittgenstein's later thought. It shows that Frege was aware of the problem of how, when constructing complex expressions out of their components, to avoid coming up with a list of names rather than a sentence. This led him to his strategy of not building a sentence out of its component parts, but of getting at the parts by breaking up a whole. Wittgenstein, despite his own “synthetic” approach, did not encounter this problem, because he followed Frege's late insight to its logical conclusion, namely that the sense of an expression consists in its use as a sign.
