L’être fatal de la famille

L’être fatal de la famille is Lucien de Rubempré’s name for the family member whose presence seems to bring ruin to those closest to him. The expression gives a pattern to his remorse: he believes that, despite his affection for his family, his actions repeatedly cause them harm. Its force comes from the gap between intention and consequence, and from Lucien’s conviction that this gap is part of who he is.

Origin and meaning

Lucien recalls hearing the theory at a dinner among friends at the Rocher de Cancale. A diplomat had described a young woman who remained unmarried as being made ill by her father, then broadened the example into a theory of family misfortune: without one mother, a household might have prospered; a son might ruin his father; a father might destroy his children’s future and standing. The company treated the argument as a witty paradox, but Lucien says its many examples struck him as a truth beneath the joking.

The expression therefore suggests more than bad luck. It describes harm generated within the family itself, through relationships that ought to provide support. Lucien applies the theory to his own conduct: his heart is full of tenderness, he says, yet he acts like an enemy. He sees the latest injury as the cruelest because it follows a life in which he has answered his family’s devotion with suffering.

Lucien’s self-accusation

Writing to Ève Séchard in the middle of the night, Lucien connects the expression to his recent return and to the consequences of his life in Paris. He contrasts the family’s steady, humble work toward security with his own attempt to seize fortune through pleasure and ambition. He admits that he mistook professional camaraderie for friendship, left genuine friends for people who wanted to exploit him, and remembered his family too often only when he could bring them distress.

His letter makes the diagnosis partly moral and partly temperamental. Lucien says that his ambitions are excessive, that the pleasures he has known poison the modest satisfactions within reach, and that his will operates only in bursts. He wants an easy life and fears the future; when faced with an inconvenience, he believes his cowardice may carry him very far. He also recognizes a mismatch between his desires and his capacity for sustained effort: he imagines himself a cedar when he may be only an elegant shrub. In his account, this imbalance repeatedly cancels his attempts to succeed and makes even good intentions dangerous.

Lucien extends the diagnosis to his dependence on other people. He imagines that a strong, merciless will could have directed him, and says that Madame de Bargeton might have been the right wife for him had he not failed to leave Coralie. He acknowledges that David Séchard and Ève Séchard could have served as pilots, but considers them unable to master a weakness that evades control. The family is thus both the source of the devotion he longs for and, in his judgment, unable to protect itself from him.

Family judgment and significance

The letter is a final act of self-condemnation as well as a farewell. Lucien tells Ève not to search for him or his fate, and frames his decision as a rejection of a future he cannot bear. His claim to be the family’s fatal member gives private guilt the shape of an inherited social pattern: one person’s weakness can damage a household’s prospects, just as the diplomat’s examples described. Lucien’s language is not an impartial verdict on his character; it is the desperate self-judgment of a man who sees his failings as both repeated and irreversible.

The phrase returns in Madame Chardon’s later lament that her son will remain fatal even when doing good. That echo broadens its meaning beyond Lucien’s own letter. What begins as a theory he adopts to explain his injuries to the family becomes, for his mother, a name for the continuing contradiction between his intentions and the harm that follows. The expression binds remorse to consequence: affection does not undo damage, and good intentions do not guarantee that a family will be spared.
