Ontological approaches to the arts have neglected art forms such as dance. This hinders analysis of the metaphysical similarities and differences between different art forms. In this paper, I develop a metaphysical realist ontological approach to dance and sport that is grounded in embodiment. I first examine the debate between descriptivism and metaontological realism in the philosophy of arts in the context of Thomasson’s descriptive approach and Dodd’s metaontological approach of folk-theoretic modesty. Following Dodd, I adopt a realist metaontological approach (...) to dance as an art form, drawing on philosophical debates within dance. I then review metaphysical approaches to sport and argue that most such approaches are based on abstract, top-down models. I therefore propose an ontological account of sport and dance based on metaontological realism and grounded in embodied movement knowledge. Drawing on Schaffer’s concept of ground functionalism, I use this approach to compare the aesthetic and bodily aspects of sport and dance in terms of elite-level movement knowledge. I describe how the embodiment of such movement knowledge through practice permits dancers and athletes to create expert movements. Drawing on findings from neuroscientific research, I argue that dancers and athletes, through the process of physiological plasticity, acquire embodied memories that are transformed into new bodily and behavioral dispositions. I believe that the metaphysical realist ontological approach presented here could help to broaden the focus in arts ontology to encompass movement disciplines such as sport and dance. This account may also engender cross-disciplinary research and encourage philosophers to explore the role of movement in arts such as music. (shrink)
