The analysis of aesthetic phenomena using scientific methods sometimes conceals the difficulties of experimental aesthetics. In the study with Bill Viola’s videoinstallation The Greeting, the discrepancy of theoretical claim and experimental reality takes shape exemplarily. The ambitious aim of dissecting the (emotional-aesthetic) perception of The Greeting follows the standards of experimental/empirical research. The data, however, offers not only confirming correlations, but also unexpected findings and interpretive impasses that force a revision of the thesis. With a retrospective view on the completed (...) experiment, the suspicion is confirmed that proving aesthetic experience with the means of the natural sciences is informative, but also limited.
