Great art, or, let’s just say, more modestly, original art is never created in the safe middle ground, but always at the edge. Originality is dangerous. It challenges, questions, overturns assumptions, unsettles moral codes, disrespects sacred cows or other such entities. It can be shocking, or ugly, or, to use the catch-all term so beloved of the tabloid press, controversial. And if we believe in liberty, if we want the air we breathe to remain plentiful and breathable, this is the art whose right to exist we must not only defend, but celebrate. Art is not entertainment. At its very best, it’s a revolution.
