Catherine and Heathcliff's unity

Catherine and Heathcliff's unity is the metaphysical engine of Wuthering Heights, a claim of absolute, soul-level identity that transcends social position, marriage, and even death. It is articulated most famously in Catherine's declaration to Ellen Dean, 'I am Heathcliff,' and in her assertion that 'whatever our souls are made of, his and mine are the same.' This unity is not merely a romantic attachment but a statement of ontological fact: Catherine and Heathcliff are, in her own account, not two beings who love each other but two beings who constitute a single self. The novel's entire tragic machinery—Catherine's fatal marriage to Edgar Linton, Heathcliff's decades-long revenge, and the haunting that follows Catherine's death—flows from this foundational claim of identity, which is at once a source of transcendent meaning and of profound destruction.

The Declaration of Identity

The fullest articulation of Catherine and Heathcliff's unity comes in Catherine's confession to Ellen Dean, a speech that is both a declaration of love and a theological meditation on the nature of her own being. Catherine explains that heaven did not seem to be her home, that she broke her heart weeping to come back to earth, and that the angels flung her out into the middle of the heath on the top of Wuthering Heights, where she woke sobbing for joy. This dream of exile from heaven serves as her explanation of her secret: she has no more business marrying Edgar Linton than she has to be in heaven. The reason is not that Heathcliff is handsome, she insists, but that 'he's more myself than I am.' She then delivers the novel's central metaphysical claim: 'Whatever our souls are made of, his and mine are the same; and Linton's is as different as a moonbeam from lightning, or frost from fire.' The comparison is not merely of degree but of kind: Heathcliff and Catherine share a substance, while Edgar Linton belongs to an entirely different order of being.

Catherine elaborates this identity in terms that make it a condition of her very existence. She tells Ellen that her great miseries in this world have been Heathcliff's miseries, that she watched and felt each from the beginning, and that her great thought in living is himself. Her most extreme formulation is conditional and cosmic: 'If all else perished, and he remained, I should still continue to be; and if all else remained, and he were annihilated, the universe would turn to a mighty stranger: I should not seem a part of it.' Her love for Linton, she says, is like the foliage in the woods, which time will change as winter changes the trees; but her love for Heathcliff 'resembles the eternal rocks beneath: a source of little visible delight, but necessary.' The speech culminates in the direct assertion, 'Nelly, I am Heathcliff!'—a statement that collapses the distinction between lover and beloved, self and other, into a single identity.

The Fatal Choice and Its Consequences

Catherine's declaration of unity is immediately followed by a decision that betrays it. Having told Ellen that she is Heathcliff, she nonetheless resolves to marry Edgar Linton, and her reasoning reveals the social and economic logic that the unity cannot overcome. She argues that if she and Heathcliff married, they would be beggars, whereas if she marries Linton she can aid Heathcliff to rise and place him out of her brother's power. Ellen Dean is quick to condemn this as the worst motive yet given for becoming the wife of young Linton, but Catherine defends it as the best: the others were the satisfaction of her whims, while this is for the sake of one who comprehends in his person her feelings to Edgar and herself. The irony is devastating: Catherine's plan to use Edgar's money to raise Heathcliff is precisely what destroys the unity she proclaims. Heathcliff, who has been listening from behind the settle, hears only that it would degrade Catherine to marry him, and he leaves before she can finish her declaration of identity. This overheard fragment becomes the seed of his revenge.

Heathcliff's response to Catherine's betrayal is not merely anger but a redefinition of their unity as a bond of mutual destruction. When Catherine later tells him that she has treated him infernally, he acknowledges it and promises revenge, but he also clarifies that he seeks no revenge on her: 'That's not the plan.' His language of grinding and crushing—'I have no pity! I have no pity! The more the worms writhe, the more I yearn to crush out their entrails!'—is directed at the world that separated them, not at Catherine herself. Even in his cruelty, Heathcliff maintains the logic of unity: Catherine is part of himself, and he cannot revenge himself on himself. The tyrant grinds down his slaves, he says, and they crush those beneath them; Catherine is welcome to torture him to death for her amusement, only allow him to amuse himself a little in the same style. The unity persists even as it becomes a mutual torture.

The Unity Beyond Death

Catherine's death does not end the unity; it transforms it into haunting. When Ellen Dean tells Heathcliff that Catherine's senses never returned, that she recognized nobody from the time he left her, and that she lies with a sweet smile on her face, Heathcliff responds with a curse that is also a prayer: 'Catherine Earnshaw, may you not rest as long as I am living; you said I killed you—haunt me, then!' He invokes the murdered haunting their murderers and begs her to be with him always, to take any form, to drive him mad, only not to leave him in the abyss where he cannot find her. His cry, 'I cannot live without my life! I cannot live without my soul!' is the inverse of Catherine's 'I am Heathcliff': if she is his soul, then her death is his annihilation. He dashes his head against a knotted trunk and howls like a savage beast, and Ellen observes splashes of blood on the bark, suggesting this was a repetition of scenes acted during the night.

Heathcliff's experience of Catherine's haunting is described in terms that literalize the unity. He tells Ellen that when he slept in her chamber he was beaten out of it: the moment he closed his eyes, she was either outside the window, or sliding back the panels, or entering the room, or even resting her darling head on the same pillow as she did when a child. He opened and closed his eyes a hundred times a night, to be always disappointed. He describes this as 'a strange way of killing: not by inches, but by fractions of hairbreadths, to beguile me with the spectre of a hope through eighteen years.' The unity that was once a source of identity has become a source of torture, yet Heathcliff cannot and will not escape it. He tells Ellen that the entire world is 'a dreadful collection of memoranda that she did exist, and that I have lost her,' and that he cannot look down at the floor without her features shaped in the flags, in every cloud, in every tree, filling the air at night and caught by glimpses in every object by day.

The Exhaustion of Revenge

The unity ultimately exhausts Heathcliff's capacity for revenge. In his final conversations with Ellen Dean, he describes a strange change approaching, a loss of interest in his daily life so complete that he hardly remembers to eat and drink. He explains that Hareton's startling likeness to Catherine connects him fearfully with her, and that Hareton's aspect was 'the ghost of my immortal love; of my wild endeavours to hold my right; my degradation, my pride, my happiness, and my anguish.' The revenge that once seemed the very purpose of his existence has lost its meaning: he has levers and mattocks to demolish the two houses, and has trained himself to be capable of working like Hercules, but when everything is ready and in his power, he finds the will to lift a slate off either roof has vanished. 'I have lost the faculty of enjoying their destruction,' he says, 'and I am too idle to destroy for nothing.' The unity with Catherine, which drove him to revenge, has also rendered revenge pointless: the destruction of her family is the destruction of part of himself.

Heathcliff's final state is one of paradoxical fulfillment and dissatisfaction. He tells Ellen that he wishes he could annihilate his property from the face of the earth, that he has not written his will and cannot determine how to leave it. When Ellen urges him to repent of his injustices, he replies that he has done no injustice and repents of nothing: 'I'm too happy; and yet I'm not happy enough. My soul's bliss kills my body, but does not satisfy itself.' This is the terminal condition of the unity: Catherine's presence, which he has sought for eighteen years, is now with him, but it cannot be possessed. The unity that began as a declaration of identity—'I am Heathcliff'—ends as a state of being that is both bliss and torment, a soul's bliss that kills the body without satisfying itself. The novel's final image of the unity is not reconciliation but exhaustion: Heathcliff's death is not a defeat but a release, the only possible conclusion to a bond that could neither be fulfilled in life nor broken by death.
