 Glanville’s work in cybernetics covered a wide range, in part because his approach was to abstract and distill but also because of the opportunities that arose in writing his regular column.Special areas of interest included his “Theory of Objects”—a theory he argued, second-order cybernetics cannot properly work without—and Black Box Theory.He developed connections between cybernetics and design, being credited by some with the creation of a new (sub-)field.
