Either criticism is no good at all (a very defensible position) or else criticism means saying about an author the very things that would have made him jump out of his boots.

Criticism does not exist to say about authors the things that they knew themselves. It exists to say the things about them which they did not know themselves. If a critic says that the Iliad has a pagan rather than a Christian pity, or that it is full of pictures made by one epithet, of course he does not mean that Homer could have said that. If Homer could have said that the critic would leave Homer to say it. The function of criticism, if it has a legitimate function at all, can only be one function—that of dealing with the subconscious part of the author’s mind which only the critic can express, and not with the conscious part of the author’s mind, which the author himself can express. Either criticism is no good at all (a very defensible position) or else criticism means saying about an author the very things that would have made him jump out of his boots.
-G.K. Chesterton, from his criticism of Dickens' The Old Curiosity Shop.
