This article analyses the concept of "aesthetic emotion" in John Dewey's "Art as experience". The analysis shows that Dewey's line of investigation offers valuable insights as to the role of emotion in experience: it shows emotion as an integral part and structuring force, as a cultural and historical category. However, the notion of aesthetic emotion is characterized by a fundamental ambiguity. There is a conflict between a mechanical and an organic understanding of emotion, a confusion of emotion as structure and of emotion as process, of emotion as content and as agency. The central problem may consist of the conception of aesthetic experience as the ideal. While evil and despair are thereby excluded from the art, everyday life is left wanting, as it cannot live up to the ideal. (Contains 8 notes.)
