But should an author's thoughts and intentions be accorded such pre-eminence? The question comes up in the second essay on Empson, of whom Kermode says that he spent 40 years "explaining ... that the purpose of criticism was to follow the movement of the author's mind". He doesn't tell us whether he agrees with this approach, and can sound vaguely sympathetic towards the idea of replacing "the author" with Foucault's "author function". Yet, writing on the Romantics, he finds the idea that poems revised over the years might not be the products of one distinct, recognisable individual "pretty appalling", and is not afraid to introduce a wealth of biographical detail, frequently derived from acquaintance, to his own commentaries. My only complaint is that it's not clear quite what the relevance of this biography is to the textual criticism Kermode evidently favours in theory, and intermittently practises.
