The sister relationship between Justine and Juliette

Justine and Juliette’s sisterly relationship begins in shared privilege, is tested by sudden poverty, and becomes the first expression of the novel’s central conflict between virtue and self-interest. When their parents’ bankruptcy leaves them orphaned and nearly penniless, Juliette treats freedom from the convent as an opportunity to pursue pleasure and security through libertinage; Justine, more sensitive to their loss and unwilling to compromise her principles, rejects her sister’s counsel. They part without promising to meet again, and that separation gives the novel’s moral opposition an intimate, familial beginning.

Identity and Background

The sisters are the daughters of a wealthy Parisian banker. They are educated together in a celebrated abbey, where they have access to instruction, books, and the accomplishments expected of young women. Juliette is three years older than Justine. At the opening of the tale, Juliette is thirty and established as Madame de Lorsange; the narrative looks back to their adolescence to explain how the sisters’ lives first diverged.

The family’s security collapses when a disastrous bankruptcy ruins their father, who dies of grief. Their mother dies a month later. Distant relatives do not take responsibility for the children: most of the inheritance is absorbed by creditors, leaving each sister only a hundred crowns. The convent opens its doors to them, gives them their small dowries, and allows them to make their own way. They have just twenty-four hours to leave and must face the world without the protection that their education and family status once seemed to promise.

Opposing Responses to Poverty

Juliette meets their release with delight. When Justine cries over their parents’ deaths and the loss of their former life, Juliette briefly tries to comfort her, then reproaches her for being too sensitive. She argues that a person should be troubled only by what affects her directly and should cultivate pleasure to blunt painful feeling. In her reasoning, survival and happiness require suppressing concern for suffering that brings no personal benefit.

Juliette turns that philosophy into practical advice. She points to a girl who has left home and is now well maintained, and argues that marriage offers no reliable happiness: it binds a woman to a husband while leaving her little pleasure. By contrast, she presents a life among lovers as a way to obtain support and protect oneself through their number. Her proposal makes material security the measure of a woman’s available choices, treating dependence on men not as a danger to avoid but as a condition to manage for advantage.

Justine is horrified. She says that she would rather die than accept what she sees as dishonor, and refuses Juliette’s repeated urgings. The disagreement is not simply a difference in temperament: it is a dispute about whether hardship licenses abandoning moral limits. Juliette sees sensibility and virtue as liabilities that can deepen suffering; Justine’s response shows that she will not accept security on those terms.

Separation and Its Immediate Consequences

Neither sister persuades the other. Juliette intends to become a woman of consequence and fears that Justine’s virtuous but socially lowly inclinations could bring her into disgrace. Justine, in turn, does not want to risk her morals in the company of someone she believes is headed toward public debauchery. Their judgments make mutual affection insufficient to keep them together: each imagines the other’s chosen life as a threat to her own prospects and principles.

They leave the convent the following day and part without exchanging a promise to meet again. The farewell is presented as an eternal one, turning a practical separation into the point of departure for two distinct lives. Juliette’s response to the rupture is consistent with the self-protective philosophy she has just preached: she does not remain with Justine or make their shared hardship the basis of a common plan. Justine, left to find assistance alone, seeks work from a woman who had known her in childhood and is turned away. The immediate rejection confirms that kinship and former affection offer little protection once she is poor and orphaned.

The Sisters Within Justine’s Recollections

Much later, Justine recounts her misfortunes to Madame de Lorsange while concealing her name and birth. She describes the circumstances of her orphanhood and hardship as the beginning of her vulnerable position, then tells of approaching Monsieur Dubourg, a wealthy tradesman, for assistance while she is not yet fourteen. His response treats her need as an opportunity to demand services rather than a reason to help her. The episode gives concrete force to the predicament over which the sisters had argued: poverty narrows Justine’s choices and exposes her to people who convert her need into leverage.

Justine also recalls that after an exploitative encounter with Dubourg, she resolves not to expose herself to a similar situation again. She leaves her lodgings, pays what she owes, and condemns the man who took advantage of her circumstances. Yet she later learns that he has received a government trusteeship that will increase his income by more than five hundred thousand pounds a year. The contrast between his advancement and her insecurity echoes the sisters’ original disagreement: Juliette’s pursuit of material advantage seems fitted to a world that rewards power, while Justine’s refusal to make wrongdoing a path to safety leaves her exposed to further hardship.

A Family Contrast and Its Social Stakes

The sisters’ separation establishes a pattern that the novel repeatedly tests: virtue does not guarantee protection, and a person’s need for support can be manipulated by those with money and influence. Justine’s experiences make clear that her vulnerability is not merely a consequence of private sensitivity. Her small inheritance, lack of employment, and dependence on strangers leave her with few secure options. In her later account, she describes a world in which poverty draws predatory attention and where the powerful may prosper after exploiting the poor.

Juliette’s early counsel and Justine’s refusal therefore frame more than a personal quarrel. They present competing responses to the same material crisis: self-interest as a means of pursuing security, and moral constancy maintained despite its costs. The sisters’ bond makes that opposition consequential from the beginning. They are not strangers divided by abstract doctrine, but daughters who share an upbringing and an abrupt fall from comfort, choosing incompatible ways to live once their family and institutional support disappear. Their parting leaves Justine to encounter the dangers Juliette’s philosophy promises to navigate, while the novel’s recurring contrast between the sisters gives those dangers a familial and moral context.
