Part I of this essay will examine how the interplay between philosophy and art over the past century is reflected in the aesthetic theories of four leading Twentieth century aestheticians: Walter Benjamin, Merleau-Ponty, Gilles Deleuze, Arthur Danto. The philosophers’ theories are linked to the developments in art most directly related to their respective approaches to problems in aesthetics. Part II will explore selected non-philosophical social and technological developments that are in the process of altering the course of contemporary art today. Among these are globalization, the art market, social/political issues, popular culture, virtual reality, and new manifestations of the avant-garde. Key factors that warrant consideration for future developments in aesthetics are identified in the hope that today’s and future aestheticians will begin to consider what changes are required in aesthetics to address these new developments in art.
