Duc de Guermantes

The Duc de Guermantes is a prominent aristocrat whose changing response to the Dreyfus Affair exposes the instability beneath the authority of social rank. First presented as a forceful anti-Dreyfusard, he later returns from a spa as a supporter of a retrial and Dreyfus’s acquittal. The reversal connects his political opinions to the people around him, while his relations with his brother, M. de Charlus, reveal the novel’s interest in family resemblance and the limits of social knowledge.

Identity and Family

The Duke belongs to the Guermantes family and is M. de Charlus’s brother. That connection is not immediately legible to Madame Verdurin: when Charlus casually identifies the Duke as his brother, she is left uncertain whether he is joking or referring to some less direct family tie. The exchange makes visible the distance between aristocratic familiarity with family titles and the assumptions of outsiders.

The narrator also places the brothers in contrast. Charlus shares his brother’s family identity and, at times, his manner of speaking, but the narrator associates Charlus’s different desires and nervous temperament with artistic gifts the Duke does not display in the same way. Charlus is described as an accomplished pianist, an amateur painter with taste, and an eloquent speaker; the contrast complicates any simple equation between inherited family likeness and shared character.

Political Position and Reversal

The Duke’s politics initially align with the anti-Dreyfusard camp. As the controversy intensifies, he treats Swann’s support for Dreyfus as a grave error by a respected man, and sees it not merely as a political disagreement but as a threat to social and patriotic solidarity. He argues that Swann’s position will encourage the belief that Jews act collectively in support of their own, turning one man’s stance into an accusation against an entire group.

The Duke’s judgment of Swann is shaped by the period’s widening divisions. The narrator notes that opposition to Dreyfus has grown more violent and has expanded from politics into social life, with patriotism and militarism among the issues inflaming public feeling. The Duke’s indignation therefore reflects more than a private quarrel: it registers the way political loyalties become tests of belonging in aristocratic society.

His own position changes after he brings forward a planned spa cure. There he meets an Italian princess and her two sisters-in-law, whose conversation and arguments persuade him that Dreyfus should be retried and acquitted. At first he is startled by their certainty and tries to answer their case with reports he considers damaging. They rebut his arguments, and he eventually returns to Paris a convinced Dreyfusard. The episode presents persuasion as a social process: the women’s intelligence, confidence, and sustained engagement matter alongside the Duke’s exposure to new arguments.

Social Influence and Characterization

The Duke’s conversion is not represented as an isolated intellectual discovery. The narrator sets it beside a recurring pattern in which a person who has held a sincere conviction is won over, over a period of months, by an intelligent couple or even a charming woman. The Duke’s reversal thus forms part of a broader observation about how personal encounters can reorganize political belief. The account does not reduce the women’s arguments to social charm; it explicitly leaves open that they are bearers of truth, while emphasizing the human circumstances through which the Duke comes to accept it.

His susceptibility also contrasts with the certainty of his earlier denunciations. At the spa he begins from the expectation that he will persuade the women, only to find that they repeatedly unsettle his case. What changes is not simply the conclusion he voices: the social confidence with which he had treated anti-Dreyfusism as settled gives way to a position formed through conversation and correction. His reversal makes political conviction appear durable enough to shape public identity, yet vulnerable to the pressures and insights of new relationships.

Narrative Significance

The Duke’s changing allegiance belongs to the novel’s larger portrayal of political division as something lived through families, friendships, and social circles rather than as an abstract contest of principles. His earlier condemnation of Swann and later defense of a retrial place him on opposite sides of the same public crisis. That sequence also offers a pointed contrast with his response to younger relatives: Saint-Loup’s Dreyfusard position had not surprised him as much, since he regarded his nephew as a young man who had gone astray, whereas Swann had seemed to him an established, level-headed figure.

The Duke’s account therefore links political judgment to social expectation. Swann’s respected standing makes his support for Dreyfus seem especially consequential to the Duke; the spa encounter, in turn, gives the Duke new company and new arguments through which to revise his own stance. His character is significant less as a consistent political spokesman than as an example of how the social world that hardens a conviction can also undo it.
