I have a friend who has a passion for black and white photos of steel mills. This is beauty to him and indeed the photograhpy one would find in a book on furnaces is excellent work. And there is beauty in a steel mill when the culture of the day and history of a people is taken into consideration. I would agrue against beauty in a picture of a garbage can no matter who took the picture.
Today there is a debate in some circles on what is art, what is beauty.
Yoko One's songs might be an example here. Is it cacaphony or is it good music. We are talking postmodernism here. The mindset of the day simply cannot have the audacity to say that one art form is good and another bad. I believe that this is a masterwork on the Christian lfe.
