The Introduction opens with a close reading of information proliferation and human–machine interfaces in James Joyce’s Ulysses to establish these themes as central to the book’s exploration of the emergent early-twentieth-century phenomenon Love labels “cybernetic thinking.” She traces biographical and intellectual connections between T. S. Eliot and Norbert Wiener (the “father of cybernetics”), provides an overview of the field of cybernetics and its definitional challenges, and proposes that a reconsideration of cybernetics’s cultural lineage – as evident in experimental modernist texts – will contribute a valuable new dimension to our understanding of both modernism and cybernetics. Eve Kosofsky Sedgwick and Adam Frank’s notion of the “cybernetic fold” is redeployed to describe the rich openness to data-processing-possibility that emerges during these decades, when high-speed computing is imaginable but not yet technologically realized. After contextualizing the project within existing media- and modernist-studies conversations, the Introduction culminates with a close reading of Wiener’s cybernetic approach to information that links his perspective on technical innovation to modernist aesthetics.
