Dennis Logue of The Elephant sez:

I just thought I’d point out that your friend’s and Dorothy Sayer’s observations about the inability of artists to articulate their visions outside of their chosen medium is one that dates back to Plato. In The Apology Socrates discusses his search for a man wiser than he. He goes to politicians, no luck. Warriors, no luck. He finally approaches artists for he is convinced that in their works they truly capture some element of truth. Sadly they can not articulate why, and they also believe that their knowledge of their particular art makes them experts at everything else. (Describe any Hollywood types you’ve heard of.)

This is proves two things first, that Plato thought and wrote just about everything first, and second, Germans love David Hasselhoff. (well maybe not the latter.)
