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.<p><i>A Bradford Book</i></p>
