abstract: Leder and Nadal (2014, this issue) examine the current state of scientific aesthetics through the lens of a prescient psychological model proposed 10 years ago. These retrospective points to several future directions of which I touch on three: the nature of aesthetic emotions, the time course of emotions in aesthetic episodes, and the relationship of art and evolution.
