Frege on Asserting

Summary: What distinguishes Freges approach to logic from the traditional ways of developing logical theory are its semantic features:logical phenomena are investigated against the background of our speaking about the world. This is manifested in the Fregean terminology in which concepts like those of sense and reference that describe the relations between the language and the world, and thereby the meanings of linguistic expressions, play central role. Freges semantic approach ensues from his orientation towards the notion of truth. According to him, the notion of truth is supremely fundamental and cannot be reduced to simpler notions. That is why, in order to elucidate it, Frege appeals to our practice of speaking and, more concretely, to the practice of making assertions. This gives an intriguing pragmatic nuance to his logical enterprise. After analyzing the relevant texts, we can say that by discussing the notion of truth in the context of the topic of assertion, Frege anticipates some important ideas that have been developed as late as in the middle of the 20th century by J. Austin and J. Searle within the framework of the speech act theory.
