What makes something art? Is aesthetic response quantifiable? For Plato, good art was art that soothed and was non-representational (or idealized), as art was a lie that inflamed the senses. For Josh Reynolds, a neo-platonist, the most important thing was to show an idealized form, representing, say, the best of all possible horses (this thinking was mocked in Candide). For Tolstoy, art should be plain, easy to understand regardless of educational level, and work to make the viewer closer to God. For the Futurists, it was something that was violent and manufactured, something that celebrated war and forward action (one of the few movements to support fascism). What is art? Can you rate it?
