Book excerpt: The contributors to Nervous Systems reassess contemporary artists' and critics' engagement with social, political, biological, and other systems as a set of complex and relational parts: an approach commonly known as systems thinking. Demonstrating the continuing relevance of systems aesthetics within contemporary art, the contributors highlight the ways that artists adopt systems thinking to address political, social, and ecological anxieties. They cover a wide range of artists and topics, from the performances of the Argentinian collective the Rosario Group and the grid drawings of Charles Gaines to the video art of Singaporean artist Charles Lim and the mapping of global logistics infrastructures by contemporary artists like Hito Steyerl and Christoph Büchel. Together, the essays offer an expanded understanding of systems aesthetics in ways that affirm its importance beyond technological applications detached from cultural contexts. Contributors.
