The later Wittgenstein is widely held to be a relativist, indeed a constructivist. By contrast, this paper argues that all appearances to the contrary Wittgenstein was a realist, and that this fact becomes almost conspicuous in his late-1940s manuscripts. His realism was a common-sense one, the only kind of realism worthy of the name. Wittgenstein’s common-sense realism has unique traits: first, an uncompromising stress on deviations from ordinary language as a source of (bad) philosophy. Secondly, his awareness of the significance of the pictorial & the motor. Thirdly, his emphasis on established use, that is, on traditions. In the later Wittgenstein, philosophical realism and social conservatism converge.
