 Those philosophers, some of whom are mentioned above, who treat lived experience as legitimate descriptive and explanatory evidence are firmly committed to the validity of practice in philosophy of dance. Analytic aesthetics philosophers, however (such as D. Davies and Montero), often find it necessarily to legitimize their recourse to practice in an explicit way. D. Davies’ view is that ontologies of art should operate under a “pragmatic constraint” that tethers their views to what can be demonstrated in practice (2009). Montero’s is that there is empirical evidence to support the idea that practitioners are experts in their domain of practice (see 2012, 2013, and 2016).
