"The best kind of critic"

“IT MAY, perhaps, be wondered whether one could possibly say a worse thing of anybody than that he has said ‘the last word’ on a subject. A man who says the last word on a subject ought to be killed. He is a murderer; he has slain a topic. The best kind of critic draws attention not to the finality of a thing, but to its infinity. Instead of closing a question, he opens a hundred.”

~G.K. Chesterton: quoted in Return to Chesterton by Maisie Ward
