There are two prevalent types of graffiti:
public graffiti, which we've all seen on buildings, billboards, subways,
etc., and "latrinalia," or bathroom graffiti. There is a lot of psychology
behind these images and messages. Graffiti has actually been used
as a form of psychotherapy. Psychiatrists at St. Joseph's Hospital
in Chicago encourage patients to write graffiti on the walls to promote
communication between patients and therapists. They often
give diagnostic insights and clues about ways of relating to patients.
I'm not saying that all graffiti is good; I just think that people rarely take the time to look deeper into things that have negative societal connotations. Perhaps the presence of graffiti simply means that we are becoming more artistic, even to the point that we are running out of places to put our art. And what better place to put art than a drab, empty wall?
