Holes and Other Superficialities

This investigation on the borderlines of metaphysics, everyday geometry and the theory of perception seeks to answer two basic questions: Do holes really exist? If they do, what are they? Holes are among entities that down-to-earth philosophers would like to expel from their ontological inventory. Casati and Varzi argues in favour of holes' existence, examining their ontology of holes, their geometry, their part-whole relations, their identity, their causal role and the ways we perceive them.
