Imprisonment

From the moment Pierre Aronnax, Conseil, and Ned Land are dragged into the Nautilus, they enter a state of captivity that Captain Nemo defines on his own terms. He declares that they are "prisoners of war" and that he has cared for them only because it serves his own interests, not out of any obligation to humanity. The freedom he offers is strictly circumscribed: they may come, go, see, and observe everything on board except under rare circumstances, but they must never hope to see their homeland, friends, or relatives again. This is the freedom of a prisoner pacing his cell, as Aronnax immediately recognizes. Nemo makes clear that he obeys none of society's regulations and that the three men are bound by no solemn promises—only by his superior force and the impossibility of escape from the depths of the sea.

The Terms and Conditions of Captivity

Captain Nemo imposes a single condition on his prisoners: they must give their word to submit without question if unforeseen events force him to confine them to their cabins for hours or days. He claims this shields them from complicity in actions they are not meant to see. Aronnax accepts this condition, but the arrangement is fundamentally one-sided. Nemo later reinforces the permanence of their imprisonment when Aronnax formally asks whether he intends to keep them forever. "Whomever boards the Nautilus must never leave it," Nemo replies, and when Aronnax calls this outright slavery, Nemo simply says, "Call it anything you like." He adds that every slave has the right to recover his freedom, and he has never tried to bind them with their word of honor—implying that they are free to try, but the attempt will almost certainly fail.

The Psychological Toll of Confinement

The imprisonment weighs most heavily on Ned Land, whose vigorous, freedom-loving nature cannot adapt to prolonged captivity. His mood grows gloomier by the day, and his anger builds until his eyes flicker with dark fire whenever he encounters Captain Nemo. Aronnax observes that the Canadian's love of freedom and hatred of slavery could lead to plans of vengeance, and he warns Nemo of this danger. Ned himself declares that he is suffocating and would rather jump overboard than remain. Even Aronnax, who initially finds scientific compensation for his lost freedom, eventually feels the strain. After seven months without any news from shore, he too is gripped by homesickness. Only Conseil, the stoic Flemish servant, seems able to accept the situation with equanimity, though even he notes that the monotony of life on board must be unbearable for Ned.

The Impossibility of Escape

The Nautilus's environment makes escape nearly impossible. It navigates underwater, far from land, and when it does approach shores, Captain Nemo is vigilant. In the Mediterranean, the ship travels at twenty-five miles per hour, making any attempt to use the skiff as rash as jumping from a racing train. When the Nautilus nears the coast of France or England, Nemo deliberately avoids populated areas. The only realistic opportunities for escape arise when the ship is close to land, but these are repeatedly thwarted by circumstances—a storm, a sudden dive, or Nemo's own maneuvers. Ned Land's plan to seize the skiff and unscrew its bolts is carefully prepared, but when the moment comes, the Nautilus submerges just as they are about to act, and they are once again prisoners.

Captivity as a Moral and Existential Condition

Imprisonment on the Nautilus is not merely physical but moral and existential. Aronnax becomes an unwilling eyewitness to Nemo's acts of vengeance, including the sinking of a warship with all its crew. He feels that he has been made an accomplice, or at least a spectator, to horrors he cannot condone. The captain's own life is a form of self-imposed imprisonment: he has severed all ties with humanity and lives in perpetual exile beneath the waves. His final cry—"Enough! Enough!"—suggests that even he finds his own captivity unbearable. The novel ends with the three protagonists escaping only through the chaos of the Maelstrom, and even then, Aronnax never learns whether Nemo survived or whether the Nautilus continues its lonely voyage. The state of imprisonment thus defines not only the passengers but the captain himself, and the sea becomes both a prison and a refuge from which there is no easy return.
