Siri Hustvedt, the author of international bestsellers such as "What I Loved" and "The Summer Without Men," has always been fascinated by biology and the theory of human perception. She loves both art and the humanities and natural sciences equally. She is a novelist and a feminist. The essays collected in this volume, which are both insightful and radical, impressively testify to her diverse talents. The first part examines the questions that influence how we see and judge art and the world in general: questions of perception and questions of gender. The foundations of this discussion include works by Picasso, de Kooning, Jeff Koons, Louise Bourgeois, Anselm Kiefer, Robert Mapplethorpe, Susan Sontag, and Karl Ove Knausgard. The second part deals with neurological disorders and, among other things, with the mysteries surrounding them.
