The allegory of Linda is very clear here: she is the "keeper" of lawful
society. As the agent of unifying government she remains herself "above the
shames and passions" of those she governs. But her "jealousy,"
on the surface referring to Nostromo and Giselle only, grammatically can refer
to all the "passions of the earth," suggesting that repressive law,
removed as it is from all the emotions of the truly human, is jealous and "alone."
