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.
