Wittgenstein und Frege über Eigennamen und das Kontextprinzip

The paper discusses the bearing of Frege's and Wittgenstein's interpretations of the Context Principle on the use of proper names. It is argued that the later Wittgenstein, unlike the author of the Tractatus, has many interesting things to say on the use of proper names that are not at variance with Frege's views. If we bear in mind the paramount importance of context in communication we may come to see Frege's and Wittgenstein's observations on the fluctuating meaning of proper names in a new perspective.
