‪This article examines Ludwig Harig’s “novel” Sprechstunden für die deutsch-französische Verständigung und die Mitglieder des gemeinsamen Marktes, ein Familienroman in the context of the historically symptomatic reception of Wittgenstein, that implicitly or explicitly manifests in many texts of the German and Austrian post-war avant-gardes. The focus will lie on the literary adoption of Wittgenstein’s theory of utterance and his concept of language-game. The literary appropriation of these figures of thought will be examined and retraced throughout the formal and procedural stage of the text. At the same time, a perspective on Wittgenstein’s reception by the Wiener Gruppe (Vienna Group) and Oswald Wiener’s critique of Wittgenstein in that context will be outlined. This position will be subsequently placed in relation to Harig’s view, scrutinizing different paths of neo-avant-garde language reflection and language criticism – always with Wittgenstein as point of reference.‪
