Libertinage

Libertinage is the novel’s name for a philosophy that treats personal pleasure and advantage as superior to conventional morality, religious belief, and obligations to others. Its proponents portray crime as a rational response to poverty and inequality, and desire as a force that neither religion nor social rules can rightfully govern. The narrative tests these arguments through Juliette’s ascent and the speeches of figures including Dubois and the Comte de Bressac, setting their confident claims against Justine’s continuing commitment to conscience and Providence. At the end, the narrator explicitly asks readers to take from the story a moral contrary to libertine doctrine: true happiness belongs to virtue, even when virtue suffers on earth.

Definition and Narrative Frame

The novel introduces Libertinage not simply as a pattern of misconduct but as an articulated challenge to the moral scheme conventional fiction usually rewards. Its preface announces an intention to present Vice triumphant and Virtue as the victim of its sacrifices, and to follow a vulnerable protagonist through repeated misfortunes rather than restore an ordinary balance by rewarding good and punishing evil. That structure gives libertine arguments room to appear persuasive within the characters’ world, even as the framing keeps their claims in contention with the narrator’s moral purpose.

The dedication calls out the “sophistries of libertinage and of irreligion” as ideas the dedicatee opposes. The narrator explains that their presence in the memoirs is necessary to the order of the characters and to the novel’s unusual moral design; portraying such doctrines is not the same as endorsing them. The preface instead treats the contrast between libertine success and virtue’s suffering as a means of provoking reflection on Providence, conduct, and the apparent injustice of worldly fortune.

Juliette’s Choice and Career

The philosophy first takes practical shape in the sisters’ separation. When the orphaned Juliette sees Justine distressed, she urges her sister to concern herself only with what affects her personally and to seek physical pleasure as a way of stifling painful moral feeling. In her account, wisdom means enlarging pleasure rather than increasing sorrow. She also argues that a woman need not expect happiness from marriage and might protect herself from dependence by choosing libertinage instead. Justine rejects both the reasoning and its proposed course, preferring hardship to what she regards as dishonor.

Juliette acts on the opposite principle. After leaving the convent, she seeks out Madame Duvergier, who takes her money under a professedly protective pretext and initiates her into a commercial sexual world. The narrative recounts this exploitation as part of Juliette’s apprenticeship, not as evidence that she began with secure power. Once she advances beyond a subordinate position, however, she adopts a deliberate ambition to commit crime on a grand scale and improve her own returns. She becomes adept at attracting wealthy men, and before reaching twenty she has ruined six whose incomes were immense. Social prestige does not restrain that success: it helps disguise her beginnings and makes her more sought after.

Marriage to the Comte de Lorsange brings Juliette an income, a house, servants, and public standing. She then conceives a plan to shorten her husband’s life so that she can enjoy wealth and status without being bound to him. Her subsequent career includes further crimes for financial gain and infanticides intended to conceal the consequences of her affairs. The narrator acknowledges the apparent prosperity these acts bring: Juliette acquires wealth, influence, and the confidence of Monsieur de Corville. Yet the narrative refuses to treat those outward rewards as proof that her philosophy has secured happiness, distinguishing visible success from inward peace and invoking the possibility of moral and divine reckoning.

Arguments from Poverty and Self-Interest

Dubois develops Libertinage as an argument about class as well as individual desire. When Justine speaks of religious principles and hopes for compensation in a better world, Dubois answers that such beliefs will leave the poor starving. She contends that the callousness of the rich helps produce the misconduct of the poor: while wealth and authority protect the privileged, the poor are asked to endure deprivation, humiliation, and punishment. In this account, crime becomes a means of correcting the inequalities imposed by the powerful and protecting a life that society otherwise makes precarious.

Dubois later gives the argument a more systematic form. She claims that a person experiences personal pleasure directly, while another person’s suffering is only an external, moral consideration; a rational egoist, she argues, will therefore choose what pleases him, even when that choice harms others. The reasoning rests on a sharp division between physical sensation and moral feeling, which Dubois dismisses as deceptive. Justine counters that this doctrine may seem to suit the powerful, but it cannot safely serve people who are weak and exposed to retaliation. She invokes the social contract and the mutual good works that sustain society: someone who offers only crimes will be opposed, whether stronger or weaker than those harmed.

The exchange makes Libertinage an argument that can be examined, rather than a self-evident truth. Dubois identifies real inequalities and the hypocrisy of those who preach restraint from positions of security; Justine answers by stressing the consequences of treating others’ interests as wholly irrelevant. Her response does not erase the danger and injustice she describes. Instead, it insists that a creed of unilateral self-interest cannot provide the vulnerable with stable protection and would undermine the social bonds on which their safety also depends.

Desire, Nature, and Irreligion

The Comte de Bressac presents Libertinage through extravagant descriptions of his sexual tastes and a wider repudiation of religion. He claims that his desires are unlike those of other men and describes them as irresistible pleasures that make moral restraint seem irrelevant. The narrative connects his pronouncements to his hostility toward his aunt, whose property he wants, and to his willingness to enlist Therese in a plan to kill her. His theories therefore emerge in scenes where philosophical argument is bound to a concrete demand that someone else participate in a crime.

Bressac’s account of religion is explicitly atheistic. He denies the existence of a Creator and appeals to Coeur-de-fer’s earlier reasoning about nature’s laws and perpetual motion. He portrays religions as instruments by which the powerful have taught the weak to accept their subjection, and he rejects religious mysteries and ceremonies as contrary to reason and nature. His later argument about killing extends the same logic: he claims that human beings cannot annihilate matter, only alter its form, and that nature is indifferent to whether matter takes one form or another. On this basis he tries to deny that killing offends nature.

The novel places those claims beside their consequences rather than leaving them as abstract speculation. Bressac’s reasoning is directed toward securing his inheritance and recruiting Therese; she refuses to assist him and retains a religious conviction that makes crime incompatible with the consolation she seeks. The contrast does not make the philosophical dispute disappear: Bressac’s arguments are given space and structure, while Therese’s answer grounds moral responsibility in her own refusal and faith. The scene exposes how a theory of nature’s indifference can be used to excuse a deliberate act against a particular person.

The Novel’s Verdict

The narrative repeatedly stages Libertinage as a powerful rhetoric of emancipation from constraints, but also as a means by which the strong rationalize using the weak. Juliette’s wealth and social elevation show that crime can prosper in worldly terms; Dubois’s speeches expose the inequalities that make her reasoning attractive to those denied ordinary security; and Bressac’s arguments translate irreligion and natural philosophy into an attempt to make murder seem permissible. These strands prevent the subject from collapsing into a simple opposition between abstract doctrine and isolated vice: the arguments are tied to poverty, privilege, desire, and the unequal distribution of consequences.

The concluding address nevertheless fixes the work’s declared moral direction. Having asked readers to witness virtue’s miseries, the narrator urges them to take from Juliette’s final change the belief that happiness is found only in virtue, and that earthly persecution may be answered by heavenly reward. Libertinage thus remains central to the novel’s design, not as a doctrine the ending confirms, but as the opposing case through which the work tests its claims about suffering, justice, and Providence.
