The Latin phrase ars gratia artis translates as $$art for art$$s sake.$$ It is a sentiment that has appeared in many discussions of art and aesthetics for hundreds of years.

It$$s a high$-$minded slogan put to bare commercial use. In our final discussion, we will return to questions of the purposes, the reasons, for art. Why do we make art? How do we define art? Why does it matter?
