Don't know what that means?—Well, I will tell you. You know, that, if you
      had a bent tube, one arm of which was the size of a pipe-stem, and the
      other big enough to hold the ocean, water would stand at the same height
      in one as in the other. Controversy equalizes fools and wise men in the
      same way,—and the fools know it.
