With over 20 years of experience in teaching and researching, Gao Minglu wrote the monograph Theory of Western Art History: Representationalism and the Turn of Art History, in which he systematically sorts out, reflects on and criticizes the theories of western art history from a non-western perspective, and creatively proposes that “representationalism” is the theme that runs through the development of western art history theories. Formed in the Age of Enlightenment, representationalism is the philosophical foundation of western modern art history and criticism theories. It is the continuation and inquiry of this subject-object dualism that constitute the history of western art and its theories. However, the theories of western art history have never gone beyond the thinking paradigm of dualism. Given that, the author outlines and elaborates on the development of western art theories in a distinctive fashion, interprets the correlation among various theories, sorts out and reconstructs the development of representationalism in western countries, and explores the new development direction and possibilities of art history theories in the future.
