Karen Lang's new book, Chaos and Cosmos: On the Image in Aesthetics and Art History, is a timely intervention. Lang brings order, by way of an original synthesis, to ideas scattered in the discursive spaces of art history. Responding to a good quarter century's worth of historiographico-critical writing, she has produced a searching and insightful book, one that is historically grounded if not a history per se. Lang reveals herself to be a superlative expositor as she invites readers to re-encounter select writings by Erwin Panofsky, Immanuel Kant, Aby Warburg, Ernst Cassirer, Alois Riegl, and Walter Benjamin. The texts she treats include some of the most challenging, most resonant, most regularly revisited works in today's critical canon. Lang's book is artfully plotted, with surprising turns.- Elizabeth Sears (X-tra Contemporary Art Quarterly)
