First coined in modernity, the aesthetic is a vague, polysemic and contested concept whose complexities arise from the variety of the ways it has been defined in the history of its theorization, but also in its formative prehistory in theories of art and beauty that preceded its modern coinage. After noting key points of that prehistory, the article traces three major modern tendencies in construing the aesthetic: as a special mode of sensory perception or experience that is relevant to life (...) in general; as a special faculty or exercise of taste focused on judgments of beauty and related qualities such as the sublime; and as a theory of fine art. The idea of aesthetic disinterestedness is critically examined, and contrasts between the concept of art in Western modernity and in pre-modern and Asian culture are also considered. (shrink)
