"Russia is old; her literature is new. Russian history goes back to the ninth century; Russian literature, so far as it interests the world, begins in the nineteenth. Russian literature and American literature are twins. But there is this strong contrast, caused partly by the difference in the age of the two nations. In the early years of the nineteenth century, American literature sounds like a child learning to talk, and then aping its elders; Russian literature is the voice of a giant, waking from a long sleep, and becoming articulate. It is as though the world had watched this giant's deep slumber for a long time, wondering what he would say when he awakened. And what he has said has been well worth the thousand years of waiting."
