I'd sent out a query on this some years ago (in vain), but there are so many new listers now it may be worth trying again.
I recall reading, many years ago, an essay by George Orwell attacking Eliot for having declined from vibrant, living language into abstract obscurantism. (I believe the essay was written after some, but not all, of Four Quartets had been published, but I may be wrong about that.) I recall in particluar a line about Eliot's use of opposites ("what you know is what you do not know", etc.") having degenerated from fresh and new into something of "a parlor trick."
At the time, I was just getting into Eliot's later poetry and remember having a fair degree of sympathy with Orwell's view (though even then I thought it overstated.) Having come to appreciate the post-conversion work more, I would like to read the essay again and see what I think of it.
I've tried to locate it on line with some fairly extensive googling, and most of what I get is Orwell on Eliot on Kipling, or references to Eliot's decision not to publish "Animal Farm." Does anyone else recall the essay I am referring to, or know where it might be located (preferably on-line)?
