Was Scott responsible for the American Civil War?

Sir Walter had so large a hand in making Southern character, as it existed before the war, that he is in great measure responsible for the war. It seems a little harsh toward a dead man to say that we never should have had any war but for Sir Walter; and yet something of a plausible argument might, perhaps, be made in support of that wild proposition. The Southerner of the American revolution owned slaves; so did the Southerner of the Civil War; but the former resembles the latter as an Englishman resembles a Frenchman. The change of character can be traced rather more easily to Sir Walter's influence than to that of any other thing or person.
