"This is an exciting epistemological experiment. It is wonderful to see how intelligent philosophers can take a modest concept, such as that of the hole, as a starting point for an immense and brilliant exercise.... The writing is delightful." -- Valentino Braitenberg, Director, Max-Planck-Institut fü r Biologische Kybernetick "The idea of "Holes and Other Superficialities" is wonderfully counterintuitive: The authors want us to think of absences as full-fledged cognitive entities. The book describes a grand variety of holes -- holes in doughnuts, tunnels through blocks, flowing gaps in regularly-spaced flowerbed, and hundreds more. There are an enormous number of beautifully-rendered illustrations of every imaginable (and often never-before-imagined) type of hole....The overlap with philosophical issues of every sort is marvelous, and the authors have a delightful sense of humor." -- Douglas Hofstadter, author of "Gö del, Escher, Bach" This fascinating investigation on the borderlines of metaphysics, everyday geometry, and the theory of perception seeks to answer two basic questions: Do holes really exist? And if so, what are they? Holes are among entities that down-to-earth philosophers would like to expel from their ontological inventory. Casati and Varzi argue in favor of their existence and explore the consequences of this unorthodox approach -- odd as these might appear. They examine the ontology of holes, their geometry, their part-whole relations, their identity, their causal role, and the ways we perceive them. A Bradford Book
