 As with the deduction of taste (see  Section 2.2),  a number of commentators have looked to Kant’s doctrine of aesthetic ideas (officially part of his account of fine art) to make sense of the free play of the faculties; examples include Rueger and Evren (2005), Kalar (2006), and Chignell (2007). A particularly detailed and thorough treatment of this approach is offered in Rogerson (2008; for an earlier and briefer treatment, see Rogerson 2004).
