A small taste:
The novel is a riot of subjectivity. To Mary Garth, Fred Vincy is the central character in Middlemarch. To Ladislaw it is Dorothea. To Lydgate, it is Rosamund Vincy. To Rosamund, it is herself.
Read the whole essay. And read the book!
(I saw this first on Educating Alice, who must get to her Guardian feeds before I do!)
