This is one case where the novel does not decoy us with a surface explanation,
and we are left to puzzle out the meaning of the line. The lesson, I take it,
that should be drawn from the War of Separation is -- Separation. I.e., knowledge
of the fundamental Separation between human souls and individual motives, which
was painfully driven home to Mrs Gould in Chapters 2-4 through 2-6, and which
has been forgotten in the blithe, triumphant unity of the new Sulaco.
