 There are other contemporary dance philosophers, some working within the analytic tradition and some not, who treat the minded agency and action involved in either choreography, performing dance, or both, as primary areas of dance interest as well. Often these are connected to normative, epistemic and ontological commitments about what dance is and why it matters (David Davies (2004), for example, treats all art, including dance art, as performance). Many of these philosophers (such as Bresnahan 2014a, 2017a, and 2019b; Merritt 2015; and Montero 2016) use both traditional philosophy, in the forms of analytic philosophy and phenomenological philosophy, and insights from research in the cognitive sciences as aids in their analysis. (For more on dance philosophy and its connections to cognitive science see  Section 4.  See also  Section 3.3 for a discussion of dance as expertise.)
