I believe one must speak, and speak truly. I believe in the power of 
language to show, to move, to heal, to build. I believe nothing is beyond 
language---or, rather, that the Nothing that is beyond language is 
containable within art. I believe that that is what art is for: to contain 
the Nothing that is beyond language. What is unsaid can be said. What is 
said can be heard... For I believe nothing is beyond knowing. I believe 
nothing is beyond saying.
