"One day I asked what connection Prince Andrei, Natasha, and the bumbling Pierre could possibly have to their very different lives? There was, as at Newport, a moment of silence. Then three students simultaneously said the same thing: "They make us feel less lonely." Thucydides wouldn't have put it in that way, but I suspect this is what he meant when he encouraged his readers to seek "knowledge of the past as an aid to the understanding of the future, which in the course of human things must resemble if it does not reflect it." For without some sense of the past the future can be only loneliness: amnesia is a solitary affliction. But to know the past only in static terms--as moments frozen in time and space--would be almost as disabling, because we're the progeny of progressions across time and space that shift from small scales to big ones and back again. We know these through narratives, whether historical or fictional or a combination of both. Thucydides and Tolstoy are, therefore, closer than you might think, and we're fortunate to be able to attend their seminars whenever we like."
