 Discussions of the metaphysics of artifacts have typically arisen only in broader investigative contexts in which they are not the primary focus of attention. In particular, the metaphysics of ordinary objects has generated a significant literature in recent years, and the puzzles about existence around which it revolves do apply to artifacts, but equally to the vast array of other ordinary objects, like stones, stars, trees, jellyfish and deer. Similarly, reflection on artifact kinds has been largely overshadowed by the vast literature on natural kinds, and discussions of artifact function exist on the periphery of the much more prominent discussions of biological function. Finally, questions about the existence of abstract artifacts have arisen in the context of investigations into the ontology of works of art. We will take up these topics in turn.
