Art has a long history, and aesthetics have changed over time. Techniques like Chiaroscuro and Contrapposto come and go. Highly developed cultures usually have highly developed art and vice versa. Art is usually a balance of ideas and aesthetics. No matter the contemporary techniques, the subject matter has usually been immediately recognizable by a lay viewer, and symbology can be decoded by the specialist. For example: is there a dove flying through a window and Mary is in the picture? That means God is impregnating Mary. But even without knowing that you can still understand the picture is of Mary and is religious in nature. Post modern art is probably the most extreme example of destruction of aesthetics in the name of pure ideas. Sometimes people say modern art can express feelings that are inexpressible by language. But I argue that either 1) there was no meaning to begin with and its all self-derives and 2) it requires being a specialist to understand the art. Its the ultimate appeal to ego since no interpretation is wrong, since there was nothing really intended.
