"Perhaps it will help you understand my state of mind if I tell you that I have lived for the most part in villages where it were better that a millstone were hanged about your neck than that you should own yourself a minor poet."
After reading that sentence, I knew I had already thought those words myself. The sentence feels like reverse plagiarism, as if Frost had to steal it from my 2011 head in order to say it in a 1913 letter.
I suppose you could see my remark as arrogant, but to me it seems to indicate a more insidious link. I've never read this biography before, nor have I read any collection of Frost's letters. So why is the man speaking what I already know by heart?
