This essay situates Wittgenstein's Tractatus and other writings of the Vienna Circle in the context of various political and artistic avant-garde movements of the early twentieth century. Despite the Circle's emphasis on logical analysis, its writings were drawn into the polemics that characterized avant-garde groups, in particular their reliance on manifestos. The essay uses the manifestos of the Vienna Circle as a lens through which to uncover the polemical and performative nature of central texts of logical positivism, including the Tractatus, (...) whose condensed, numbered, and pointed sentences echo central features of twentieth-century manifestos.
