Read it through once

Then comes Sir Walter Scott with his enchantments, and by his single might checks this wave of progress, and even turns it back; sets the world in love with dreams and phantoms; with decayed and swinish forms of religion; with decayed and degraded systems of government; with the sillinesses and emptinesses, sham grandeurs, sham gauds, and sham chivalries of a brainless and worthless long-vanished society. He did measureless harm; more real and lasting harm, perhaps, than any other individual that ever wrote. Most of the world has now outlived good part of these harms, though by no means all of them; but in our South they flourish pretty forcefully still. Not so forcefully as half a generation ago, perhaps, but still forcefully. There, the genuine and wholesome civilization of the nineteenth century is curiously confused and commingled with the Walter Scott Middle-Age sham civilization; and so you have practical, common-sense, progressive ideas, and progressive works; mixed up with the duel, the inflated speech, and the jejune romanticism of an absurd past that is dead, and out of charity ought to be buried. But for the Sir Walter disease, the character of the Southerner--or Southron, according to Sir Walter's starchier way of phrasing it--would be wholly modern, in place of modern and medieval mixed, and the South would be fully a generation further advanced than it is. It was Sir Walter that made every gentleman in the South a Major or a Colonel, or a General or a Judge, before the war; and it was he, also, that made these gentlemen value these bogus decorations. For it was he that created rank and caste down there, and also reverence for rank and caste, and pride and pleasure in them. Enough is laid on slavery, without fathering upon it these creations and contributions of Sir Walter.
