Wittgenstein’s Limits of Language and Normative Theories of Assertion: Some Comparisons

In his classic work on Wittgenstein’s Tractatus (1960) Erik Stenius described Wittgenstein’s study as a critique of pure language, thus pointing to a connection between Wittgenstein’s philosophy and Kant’s critique of pure reason. Besides similarities, there also seems be important differences between the two philosophers. In Kant’s critique, one discerns a subject who does something, namely, constructs the world of experience, while Wittgenstein draws a picture in which neither an agent nor an act is visible. Like Kant and Wittgenstein, contemporary normative theories of assertion are also interested in limits, although in limits set to assertions. They appear to pay special attention to the one who asserts and to the act of asserting. This paper is an effort to search for the traces of normative theories of assertion in Wittgenstein’s Tractatus by focusing on the one who uses language and on the limits of that use. It is shown that both in Wittgenstein and in normative theories of assertion, there is an important ethical dimension, which, however, plays different roles in the two approaches. It is argued that despite the differences in the ways of construing the limits of language, Tractatus and normative theories of assertion share similar ethical concerns.
