I choose to look at Ai Weiwei, who is a an outspoken human rights activist, and often uses sculpture as his means of communicating to the public. He even said that being an artist gives him more freedom to talk about politics, because people will accept art more than simply politics.
In one of his interviews, Ai Weiwei talks about a project which has 2000 backpacks symbolizing the 2000 students died in an earthquake. The backpacks are neatly organized in huge blocks, and a sound device reads out all the names of the students. The sculpture is called Untitled (2011), and the soundtrack is called Remembrance (2010). Through this project, Ai Weiwei is trying to convey a sense of empathy through directly viewing something that’s closely related to these students – backpacks. But I find Ai Weiwei’s work a little bit confusing, because some of them are highly repetitious, and uses ready-made materials. This is very similar to Duchamp’s works, who’s famous for the urinal. I don’t see a lot of point in art in both of the artists.
