What's to say that someone with an amazing gift for words couldn't put into words an artist's ideas better than the artist could? Is it not the point of most art to convey an idea or expression? And if the art is purely to evoke emotion, it is almost impossible to convey an emotion in art that you could not put into words with a skilled hand. I think you put too little faith in the power of language and how it can be woven into intricate and amazing ideas. If it were not for language, civilization would never have developed or flourished, and is the essential mortar keeping it together because it keeps us all connected.
