Work and Object is a study of fundamental questions in the metaphysics of art, notably how works relate to the materials that constitute them. Issues about the creation of works, what is essential and inessential to their identity, their distinct kinds of properties, their amenability to interpretation, the conditions under which they can go out of existence, and their relation to perceptually indistinguishable doubles (e.g. forgeries and parodies), are raised and debated. A core theme is that works like paintings, music, literature, sculpture, architecture, films, photographs, and multi-media installations, have fundamental features in common, as cultural artefacts, in spite of enormous surface differences. It is their nature as distinct kinds of things, grounded in distinct ontological categories, that is the subject of this enquiry.
