This book is a scientific anthology and a text mosaic on the modern interior, its origins and its historic development. In recent years, science has increasingly focused on the subject of the interior; this book investigates the subject from different perspectives, the resumé of a symposium at the Sigmund Freud Museum in Vienna. Experts in the fields of architectural history, philosophy and psychology analyze the modern trend towards the individual design of interiors beyond fashion and good taste; the atelier and practice of Lucian and Sigmund Freud, the interiors in Proust's novels, Wittgenstein's house and Kiesler's Endless House.
