 Some have argued that what aesthetic properties depend on (their “dependence base”) extends beyond the intrinsic physical and sensory features of the object of aesthetic assessment (Walton 1970), who follows Gombrich 1959, especially p. 313). The nonaesthetic dependence base, Walton thinks, always includes “contextual properties”—matters to do with the origin of the work of art, or other works of art. Others dispute this (Zangwill 1999). This is one aspect of debates over formalism in many domains. These issues are important and they are a matter of substantive aesthetic differences in the approach to making and appreciating various arts, and also in the aesthetics of nature. But such debates all presuppose that some dependence thesis holds. The controversial questions are about the extent of the dependence base of aesthetic properties, not whether aesthetic properties have some nonaesthetic dependence base.
