way i look at it, greatness quite clearly exists as a concept serving a linguistic purpose, irrespective of whether it corresponds with some transcendent and objective Greatness with a capital G. seems to me that all discussions of greatness inevitably end up discussing what qualities cause something to *pass the test of time*, and that certain people can be better at sussing out these qualities than others. this of course doesn't necessarily provide a reason for an individual to prefer whichever qualities are posited - rather, it is merely a process of describing what the majority over time (and perhaps place?) find to be of most worth.
these days i'm inclined to fight the straight up "it's all opinion" slant if only because it encourages people not to challenge themselves and look at things in different ways; if i hadn't become fascinated by an idea of greatness running through the metal community then i'd probably never have put the time and effort into, say, black metal and fallen in love with it. you get the kinds of people who don't like 'paradise lost' upon a first read, and because they aren't even the slightest bit intrigued by greatness they'll be perfectly content in never reading it again, preferring the way their initial opinion helps define them be an individual with unique tastes. problem with this is that the books that last the test of time tend to genuinely be universal, meaning that with a couple of re-reads and a bit more experience that person would more than likely have ended up really enjoying 'paradise lost'.
my attitude is that whilst i refuse to accept that something i love is bad or something i hate is great just because it has classic status, i'm also aware that some extra experience and effort will in many cases cause my opinion to change significantly, especially where classics are concerned. it's a matter of not being a dogmatic cunt about your opinions, at least until you've approached the book or poem or album in question from a number of different sides.
some new questions then:
how many chances ought a work of art be given?
if it's labelled 'great' should it be given more chances than one that isn't?
is it reasonable to say that when we pigeonhole ourselves into liking certain qualities in art and not others, we are stubbornly clinging to our identities and unnecessarily denying ourselves an array of pleasures outside our little bubbles? is there a solution to this which doesn't involve becoming totally amorphous, as in, giving things an infinite amount of chances and so never committing to a position about anything?
kind of wish id started a new thread for this now haha. maybe a mod could split it or something.
