Class difference and shared human nature

Class difference and shared human nature are joined in Martin Eden through a tension between what social position does to people and what it cannot make them cease to be. Martin sees class written in work-shaped bodies, guarded expressions, clothes, and habits of speech; he also comes to believe that people on opposite sides of the divide share fundamental bodily and emotional capacities. That recognition makes Ruth Morse seem reachable to him, but it does not dissolve the material and cultural distance that gives the relationship its force.

Class as a Visible, Embodied Difference

The idea first takes shape in a street encounter. While walking with Ruth, Martin sees Lizzie Connolly and her friend beneath the electric lights of Broadway. He lifts his hat, an act that registers his continuing connection to working-class people even as he accompanies Ruth through a different social world. Lizzie looks boldly at him, then surveys Ruth’s face, dress, and station. Ruth, in turn, notices Lizzie’s cheap finery and the distinctive hat worn by working-class girls. Their brief exchange makes class legible through appearance before either woman explains it.

Ruth calls Lizzie pretty, and Martin responds by interpreting the visible differences as consequences of lived conditions rather than innate character. He explains that years of long hours at machines can mould a young body, just as years at sea have shaped his own rolling gait. He contrasts that with the bow-leggedness he imagines would have resulted from years of cow-punching. In his account, the body records the labor it has been made to perform. Lizzie’s hard eyes, too, signify a life without shelter: Martin reasons that a girl forced to take care of herself cannot preserve the soft, gentle expression Ruth possesses. Ruth accepts the explanation and feels pity for Lizzie. The scene thus locates class not only in wealth or rank but in labor, exposure, bearing, and the conditions under which a person has had to live.

Martin’s insight is also self-directed. That night, looking at himself in the mirror, he asks where he belongs. He imagines his proper place among the people of toil, in dirty surroundings and amid the smell of rotting potatoes, and sets that identity against the books, music, paintings, and cultivated language he has begun to pursue. His desire for knowledge and beauty feels like a departure from his class origin, while his love for Ruth seems to carry him toward a world far beyond his own. The contrast makes class more than an external label: in Martin’s self-questioning, it becomes a conflict over belonging, aspiration, and whether education can alter the place assigned to him.

Shared Humanity Across the Divide

A later moment between Martin and Ruth unsettles his belief that upper-class love follows rules fundamentally different from those among working people. After Martin mentions that he loved Ruth first and speaks of other women, Ruth bursts into tears. He comforts her with kisses and caresses, and her tears and jealousy force a revision of the distinction he had drawn between women of different classes. Recalling Kipling’s line, The Colonel’s lady and Judy O’Grady are sisters under their skins, Martin decides that the novels he had read had misled him: the same bodily pressures and caresses that could win a working-class girl could affect a woman from Ruth’s social world as well.

For Martin, this is not merely a discovery about courtship. It establishes a basis for imagining intimacy across the class boundary. Ruth’s purity, culture, and beauty had seemed to place her on a height beyond his reach; her intense response makes her recognizably human to him, with capacities for love, hurt, and jealousy that he associates with people across social ranks. The recognition brings her closer in his mind and makes marriage seem possible. He reasons that class is the difference separating them, but that it is extrinsic rather than fundamental and therefore, in principle, could be cast off. His thought that a slave had risen to the Roman purple supplies an analogy for the upward passage he imagines for himself.

The Limits and Uses of Martin’s Idea

The novel’s account of common humanity does not simply cancel its account of class. In the Broadway encounter, Martin and Ruth can recognize Lizzie’s beauty and circumstances, but their different positions remain visible in their clothes, expressions, and ways of moving through the world. Martin’s own body carries the history of sea labor, while his cultivated pursuits and his love for Ruth create a painful sense that he is trying to cross away from the people among whom he believes he belongs. Shared feeling does not make those histories interchangeable.

Martin’s conclusion that class can be shaken off is therefore both an assertion of human equality and a measure of his longing to rise to Ruth. The argument gives him emotional permission to imagine a marriage that his earlier reading had made seem impossible; it also reframes his ambition as a struggle against a social distinction he regards as external to human nature. Yet the novel has just shown that class becomes embodied through work and protection, and that its signs can be read on the face and in the body. The tension between those claims gives the concept its significance: people may be sisters under their skins, while the conditions of their lives still shape how they stand, look, and belong.
