Despite there are many university classes entitled “Psychology of art”, and a noticeable production of scientific literature accumulated over the years around psychological aspects concerning art, I argue here that psychology of art still does not exist as an independent subject of research. The main ways in which psychology addressed art are discussed, and the problems and limitations of such approaches are pointed out. An integrated approach to the foundation of psychology of art as an independent psychological science is sketched out. The reasons why it should exist, what it should focus on, and how (the methods) research should be conducted are just announced, pending an appropriate discussion with those interested in a manifesto for an independent psychology of art.
