Nostromo

The San Tomé silver mine is Nostromo's real protagonist, in the sense that every human character's fate bends around it: Charles Gould inherits his father's ruined obsession with the mine and rebuilds it as an idealistic instrument of order and stability for Costaguana, only to watch that idealism curdle, by the novel's end, into the same possessive, amoral 'material interests' he set out to redeem the country from. Conrad's famous, bitter formulation — that material interests, once let loose, 'are given a moral cover' by whatever ideals happen to be riding on them at the time — is less a throwaway line than the whole novel's thesis, illustrated across dozens of characters who each believe their motives are separate from the silver's and are each, eventually, revealed to be instruments of it.

Nostromo himself, the 'incorruptible' Genoese sailor whose entire social value depends on other people's need for someone reliably self-sacrificing, is quietly destroyed by the one act of theft the narrative structure works hardest to obscure: entrusted to save the silver from revolutionary capture, he and Martin Decoud sink the loaded lighter offshore, and Nostromo — believing himself abandoned and unrewarded by the very oligarchs who built his reputation on his unrewarded selflessness — secretly starts drawing off the recovered treasure for himself, becoming, in private, exactly the kind of man his public reputation had always denied he could be.

Martin Decoud's suicide, alone for days on the Great Isabel with the hidden silver and no audience left to perform his skepticism for, is the novel's bleakest set piece: a man whose entire personality was constructed out of ironic detachment and an audience of Parisian salons discovers that irony has no traction against total solitude, and simply shoots himself rather than continue existing without anyone to be witty for — Conrad's harshest verdict on a certain kind of self-regarding modern intelligence.

Where Heart of Darkness compresses its critique of imperial extraction into a single claustrophobic river journey and one European's collapse, Nostromo widens the same argument into a full invented national history — political factions, revolutions, foreign capital, decades of backstory — set in the fictional South American republic of Costaguana rather than the real Congo. The panoramic scale lets Conrad trace how material interests entrench themselves at the level of an entire society's institutions rather than one man's psyche, and the two novels are worth reading against each other as the same diagnosis delivered at two radically different magnifications.
