Hope for a definition

Weitz looks at art the same way that Wittgenstein looks at language, that is, in terms of "family relationships."  They say that these categories have no solidly defining traits, that there is no one trait or set of traits that links the parts of these categories.  Instead, they say, the components of these categories are linked by family relationships.
I find it tempting to accept this explanation--we haven't collectively come up with a definition of art yet, and all of the different essays argue rather different and sometimes conflicting points (with varying degrees of finesse).  Maybe there isn't even one trait that all works of art share.  With all of art's categories and subcategories, it is easy to be overwhelmed.  However, it seems that art should have a definition, otherwise it becomes this unexplainable force, something practically omnipotent. 
To some, like Bell, it may well be omnipotent.  To others, like Dewey, it may be ordinary but also the work of a Creator or nature itself.  But I think that, while that art is undeniably powerful, it is not beyond our grasp. 

This post brought to you by graffiti

In the women's restroom on the lowest level of Venable, there is some somewhat unusual graffiti (along with the standard "I <3 Jim H.," etc).  On one of the walls is written the line, "To Avalon we line the streets."  I was always a bit intrigued by this, figuring it was a quote but not knowing what the quote was from.  Maybe some epic tale or poem?  No.  Not really.
It's actually from the Hanson song "Lay Me Down."
I admit, when I Googled the line, I didn't expect to come up with that.  Having spent many of my formative years listening to my parents' favorite lite rock station, I didn't know much popular music as a kid.  I didn't think this was a typical line for pop songs, though.  I have to wonder whether or not that line was an organic part of the song-writing process, or if whoever wrote the song put it in afterwards because it sounded cool.  Maybe they'd always wanted to use the line and didn't know where else they could put it.  I guess it's a silly subject for a blog post, particularly since I'm not sure where most pop music fits under the umbrella of art, but it made me think, so I thought I'd share.
