Of course surgeons aren't crying over the beautiful body they have to cut open, and thank goodness for that, otherwise a lot of us would be dead.
No one has explained where the 'objective' element comes into literary criticism.
A surgeon has to cut open flesh to cure. He/she has to know where to cut and what bits to cut out. There is little room for debate about that.
A book can be read and interpreted in a thousand different ways. Yes, I am sure I can learn a lot about a narrow strata of upper middle class society from reading Jane Austen but to say that reading the novels of authors of the time is more than just adding colour to a historical analysis of conditions at the time is just bonkers. It is a frequent criticism of Austen that she is so narrow - no discussion of all the horrible wars going on at the time etc.
I care little for that because I don't read her to understand the political/social/economic situation of England in late 18th century. I read and enjoy her for her treatment of universal themes of love, loss and compromise.
My life would not be enriched one iota by reading what somebody else thought about her work. I am simply not interested. If someone else tells me Jane Austen is crap - as did Mark Twain who I greatly admire - that is their opinion. I don't agree with it, they are entitled to have it and it doesn't greatly interest me because it is all wholly subjective.
Of course, others may not agree with me and may find that ploughing through essays of literary criticism is what makes their day. Well, good for them.
But this thread addresses another point; this isn't a battle between arts and sciences and which is 'best', we aren 't talking about that. (But I would say it is probably the biggest problem our country has that for so long we were in the grip of an elite who despised science and thought only Latin and Greek were fit topics of study)
We are talking about the depressingly practical point of the path our children are to take in terms of higher education, now that it is no longer free.
So I stand by what I say; if you want to spend your time talking about what other people create, think long and hard about the institution you go to. If what you want to do is of limited use or enjoyment to the vast majority of people so you will NEED the credibility of a very good university, unless you want to risk chucking your tuition fees down the drain.
