1 Introduction

1.1 Emily Brontë and Wuthering Heights

1.1.1 Emily Brontë

Emily Brontë (1818-1848), one of the most renowned Brontë sisters in 19th-century English literature, is a distinctive literary figure celebrated for her profound insight into human nature and unique artistic style. Living a secluded life in the Yorkshire moors for most of her life, the wild and desolate natural landscape of her hometown became the spiritual source of her literary creation, endowing her works with a bold, unrestrained, and deeply emotional artistic temperament. Wuthering Heights is her only novel, a masterpiece that was once underappreciated for its bold depiction of extreme emotions and dark human nature, but later recognized as a classic of English Gothic and romantic literature, securing her immortal position in the history of world literature.

1.1.2 Wuthering Heights

Wuthering Heights is Emily Brontë’s masterpiece, and it is a cornerstone of English Gothic fiction, which unfolds a tragic story of love and revenge set against the backdrop of the bleak and untamed Yorkshire moors. Centered on the twisted love between Heathcliff and Catherine Earnshaw, the novel portrays intense emotional conflicts, cyclical vengeance, distorted human relationships, and the desolate atmosphere of human existence under the grip of extreme desires. Distinguished from traditional romantic novels of its time, it abandons gentle and conventional emotional outpouring and instead exposes the raw, primitive side of human nature with its turbulent narrative rhythm and gloomy Gothic aesthetic style. For more than a century, the novel has been acclaimed as a “dark classic” for its unique artistic charm and profound ideological connotation, becoming a perennial research focus in the field of English literary criticism.

1.2 Literature Review

1.2.1 Domestic Literature Review

In Chinese academic circles, research on Wuthering Heights has experienced a gradual deepening from superficial thematic interpretation to in-depth aesthetic and ideological analysis. Early domestic studies mainly focused on the novel’s thematic connotations, such as the criticism of class oppression, the interpretation of tragic love, and the analysis of character images, with scholars exploring the root causes of the tragedy from social and humanistic perspectives. For example, Fu and Sheng (2005) analyzed the human nature of the male protagonist Heathcliff in depth, through the main line of love and hatred in Emily Brontë’s novel Wuthering Heights, and the incentives of society and the times are revealed. In recent years, domestic research has expanded to multiple theoretical dimensions, including Gothic literary criticism, literary ethics, psychoanalytic interpretation, and aesthetic style analysis; some scholars have also attempted to combine Western aesthetic theories with the novel’s artistic characteristics for cross-disciplinary research. For example, Gong and Ye (2024), taking Wuthering Heights as an example, this paper uses the theory of acceptance aesthetics to conduct in-depth research on the reading of literary classics, clarifies the role of reception aesthetic theory in the reading of literary classics, and integrates it in the reading of Wuthering Heights. However, studies that specifically take Thomistic aesthetics as the theoretical framework to systematically interpret the dark beauty of Wuthering Heights remain scarce, and there is a lack of in-depth exploration of the dialogue between the novel’s dark aesthetic connotation and Aquinas’s classical aesthetic principles.

1.2.2 Foreign Literature Review

Foreign research on Wuthering Heights has a long history and a diverse range of perspectives, forming a rich and systematic research system. Western scholars have conducted in-depth discussions on the novel from the perspectives of Gothic tradition, romanticism, feminist criticism, postcolonialism, and psychoanalysis. For example, Marziyeh and Abolfazl (2024) examine the significant effects of trauma on Catherine Earnshaw in Emily Brontë’s Wuthering Heights, with a particular emphasis on how her encounters with mistreatment and emotional neglect lead to behaviors associated with Borderline Personality Disorder (BPD). It places Catherine’s psychological turmoil within the wider framework of Trauma Studies, applying theories related to Post-Traumatic Stress Disorder (PTSD) to analyze her interpersonal dynamics and emotional responses. Nevertheless, foreign academia has not yet carried out a systematic and in-depth study on the recontextualization of Aquinas’s three aesthetic principles by Wuthering Heights, and the research on the integration of Thomistic aesthetics and the novel’s dark aesthetic analysis still has a large exploration space.

1.3 Research Innovations

Thomas Aquinas, a pivotal figure in medieval philosophy, proposed three core aesthetic principles—integritas (integrity), consonantia (proportion), and claritas (clarity)—which have long served as a foundational theoretical framework for classical aesthetic criticism. In traditional literary criticism, Aquinas’s aesthetic theory is mostly applied to interpreting canonical texts characterized by harmony, order and sacredness, where the organic unity of content and form, the balanced coordination of internal elements and the manifestation of divine or moral radiance are regarded as the ultimate criteria for judging beauty. However, this application scope has long confined Thomistic aesthetics to the interpretation of conventional beauty, making it seem incompatible with literary works that take darkness, chaos and extremeness as their core traits. Yet this very limitation invites a methodological innovation. By applying the Thomistic aesthetic principles analogically rather than in their traditional mode, this study develops a new analytical tool for non-classical literary forms. This approach bridges theological aesthetics and Gothic literary criticism.

Wuthering Heights, Emily Brontë’s magnum opus, is a typical example of such works that seem to deviate from classical aesthetics. Known for its violent emotional conflicts, gloomy Gothic narratives and wild moorland settings, the novel has always been labeled as a “dark classic”. The raging hatred between Heathcliff and Hindley, the destructive love between Heathcliff and Catherine, the distorted human nature under extreme desire, and the desolate atmosphere permeating the whole story all seem to run counter to the harmonious and sacred aesthetic pursuit advocated by Aquinas. For a long time, scholars have mostly interpreted the novel’s aesthetic value from the perspectives of Gothic tradition, romanticism or psychoanalysis. At the same time, few have attempted to establish a dialogue between its dark beauty and Aquinas’s classical aesthetic theory.

Against this background, this study takes Aquinas’s three aesthetic principles as the entry point. It puts forward two core research questions: first, how does Wuthering Heights reconstruct the connotations of integrity, proportion and radiance in a reverse way to form a unique dark beauty? Second, what kind of dialogue tension does this recontextualization form with Aquinas’s original aesthetic theory, and can it expand the interpretation boundary of Aquinas’s aesthetics? Primarily, the study breaks the long-standing oppositional cognition between Gothic dark narrative and classical Thomistic aesthetics in academic quarters and reveals that Wuthering Heights does not deviate from Thomistic aesthetics but extends its interpretation scope through the deformation and reconstruction of the three core aesthetic elements, filling the research gap of the dialogue between the novel’s dark beauty and Thomistic aesthetics in both domestic and foreign academia. Furthermore, it verifies the inclusive nature and theoretical elasticity of Aquinas’s aesthetic theory from a new perspective, proving that this theory is not only applicable to interpreting traditional harmonious beauty but also has strong explanatory power for atypical literary beauty represented by dark aesthetics, enriching the contemporary theoretical connotation of Thomistic aesthetics. Just as crucially, the study constructs a “recontextualized model” of Thomistic aesthetics for the analysis of non-classical literary forms by taking Wuthering Heights as the research object, which provides a new transferable methodological reference for the cross-disciplinary research of theological aesthetics and Gothic literary criticism. In essence, this study performs a paradoxical alchemy, transmuting the radiant principles of Thomistic beauty within the tempestuous world of Wuthering Heights, and in doing so, constructs a transferable methodology for cross-disciplinary aesthetic analysis.

2 The Thomistic Triad of Beauty: Integritas, Consonantia, and Claritas

To establish a meaningful dialogue between the seemingly discordant realms of Thomistic aesthetics and Gothic darkness, it is first necessary to delineate the core principles of Aquinas’s theory of beauty. Rooted in his overarching philosophical maxim that “grace does not destroy nature but perfects it” (Aquinas, 1947), Aquinas’s aesthetic thought posits beauty as the rational apprehension of an object’s intrinsic form and perfection. For Aquinas, beauty is not merely a subjective impression but an objective property that elicits pleasure through intellectual recognition. This apprehension is conditioned by three constitutive criteria: integritas (integrity or wholeness), consonantia (proportion or harmony), and claritas (radiance or clarity). These are not arbitrary attributes but interrelated dimensions through which the essence of a thing manifests itself to the contemplative mind.

Beauty includes three conditions: integrity or perfection, since those things which are impaired are by the very fact ugly; due proportion or harmony; and lastly, brightness, or clarity, whence things are called beautiful which have a bright color (Aquinas, 1947). The first tenet of it is integritas, which denotes wholeness or completeness in its etymological and theoretical connotation. For Aquinas, integritas refers to the perfection and self-sufficiency of a being, requiring that all constituent parts of an object are fully realized without deficiency or imperfection, and that each part is subordinated to the organic unity of the whole. In the domain of aesthetic criticism, an integral literary or artistic work must constitute a closed, self-consistent organic system where no component is redundant or dispensable, and every detail serves the expression of the work’s essence. Notably, this integrity transcends mere formal or structural completeness, encompassing logical coherence and thematic unity, which together enable the work to present its intrinsic nature holistically.

The second essential aesthetic condition is consonantia, which can be rendered as due proportion, harmony, or consonance. Aquinas emphasizes that consonantia consists in the rational coordination, symmetry, and order among the internal elements of a thing, in accordance with the inherent laws of reason. This conception of proportion is not confined to quantitative balance in form. Still, it extends to qualitative harmony across multiple dimensions: in literary creation, it encompasses the congruence between content and form, the balance between emotional expression and rational arrangement, and the consistency between narrative structure and thematic purport. In the tradition of classical aesthetics, consonantia is regarded as the concrete embodiment of rational order; only entities conforming to such proportion can evoke authentic aesthetic pleasure, as they align with human reason’s innate inclination to pursue order and regularity.

The third and most fundamental aesthetic principle is claritas, commonly interpreted as clarity, radiance, or intelligibility. For Aquinas, claritas constitutes the quintessential attribute of beauty, referring to the distinct manifestation of a thing’s essence. Rooted in his theological ontology, this “radiance” is the projection of divine glory in the natural and artistic realms—it is the spiritual light that penetrates the phenomenal appearance of things, enabling human beings to apprehend their true essence directly through rational contemplation. In literary works, claritas is manifested in the work’s capacity to reveal the essence of human nature, the truth of existence, or the meaning of life with clarity and depth, such that the core connotation of the work becomes perceptible and intelligible to the rational audience.

Beyond the three core conditions, Aquinas’s aesthetics encompasses two distinctive traits that are pivotal to its application in literary criticism. First, beauty is correlated with goodness yet ontologically separable from it. Aquinas argues that beauty and goodness share a common origin in the perfection of a thing, but diverge in their teleological orientations: goodness is oriented toward practical utility and moral value, satisfying human appetitive desires, while beauty is oriented toward the intuitive contemplation of form and essence, independent of practical ends. This distinction implies that a literary work may possess aesthetic value even if it does not conform to traditional moral norms. Second, Aquinas defines aesthetic experience as a rational contemplative activity. Unlike pure emotional arousal, aesthetic appreciation demands the exercise of reason to perceive the integritas, consonantia, and claritas of an object, thereby attaining a profound understanding of its essence and achieving spiritual fulfillment. The aesthetic experience, therefore, becomes a distinct mode of rational engagement with the world, which will prove essential for engaging with the morally ambiguous yet formally compelling universe of Wuthering Heights. This triad, integritas, consonantia, claritas, thus provides not a rigid checklist but a flexible, profound lens for discerning the logic of beauty, a lens we now turn to the stormy moors of Emily Brontë’s masterpiece.

Traditionally, Aquinas’s aesthetic framework has been predominantly employed to interpret literary works marked by harmony, sacredness, and rational order, where the three aesthetic elements are presented in a direct, positive form. Nevertheless, this does not indicate the framework’s inherent limitation to such works; its rational core and logical flexibility actually provide a viable theoretical perspective for interpreting non-typical forms of beauty, laying the necessary groundwork for exploring the dark beauty in Wuthering Heights within the framework of Aquinas’s aesthetics.

3 The Dark Narrative of Wuthering Heights and the Reverse Interpretation of Aquinas’s Three Aesthetic Elements

In the first volume of Summa Theologia, Thomas Aquinas stated: “There are three requirements for beauty. First, integrity or perfection, for whatever is imperfect is ugly; second, due proportion or harmony; third, clarity. Hence, things of brilliant luster are universally acknowledged to be beautiful. Even if the subject itself is ugly, its image is beautiful so long as it is depicted with completeness.” (Ma, 1987) Thomas Aquinas’s triadic formulation of beauty establishes a paradigm for perceiving the beautiful as an ontological splendor reflecting divine order and truth. In its classical theological context, this triad points towards harmony, rational order, and the luminous manifestation of essence under God’s light. While Aquinas’s framework is traditionally associated with the contemplation of sacred beauty and rational order, Emily Brontë’s Wuthering Heights defies this canonical interpretation by embedding these three elements within a dark, turbulent narrative universe. Instead of conforming to the ideal of divine harmony, the novel reverses and recontextualizes integritas, consonantia, and claritas through the lens of Gothic darkness, creating a unique aesthetic system that resonates with the raw, unvarnished truths of human nature and existential struggle. This section proposes a methodological innovation: it treats the novel not merely as an object of aesthetic analysis, but as an active agent of theoretical reconstruction. By examining how Brontë deconstructs and reconfigures Aquinas’s triad, this study develops a “recontextualized model”, which is a transferable analytical framework that can be applied to other non-classical literary forms. This model operates through three analytical moves: the displacement of the object’s completeness from harmony to self-contained darkness, the reconfiguration of proportion from rational order to Gothic symmetry, and the secularization of radiance from divine light to immanent human truth. Each move demonstrates how a classical theoretical framework can be methodologically inverted to illuminate works that seem to resist it. It will discuss how Wuthering Heights reinterprets Aquinas’s tripartite theory of beauty, transforming its transcendent and rational underpinnings into a deeply secular, visceral, and haunting aesthetic experience.

3.1 The dark integrity of Wuthering Heights

Aquinas’s integritas denotes a thing’s holistic perfection: a harmonious, unified entity unblemished by any lack of its essential attributes, amounting to the state of being an organic, complete whole. Wuthering Heights constructs a narrative world that manifests a dark form of wholeness rather than Thomistic ontological integritas. Its dark wholeness arises from a closed, self-contained, and causally coherent narrative system, not from classical harmony or moral perfection.

The novel builds a fiercely isolated narrative cosmos demarcated by two manors, Wuthering Heights and Thrushcross Grange, and the moors enveloping them. Psychologically and narratively severed from the broader world of social norms and temporal progress, this geography functions as a petri dish for a self-sustaining emotional ecosystem. Within this closed circuit, the logic of a “malformed organism” operates with unrelenting completeness. The narrative unfolds along an ironclad causal chain that resembles natural law: Hindley’s maltreatment of Heathcliff begets the latter’s revenge, which ruins Hindley and entraps the next generation; Catherine’s choice of Edgar Linton rends her bond with Heathcliff, triggering her psychological collapse, his moral degradation, and the systematic ruin of their children—young Cathy and Linton. Every character is ensnared in this causal web, with no external saviors or deus ex machina to intervene; the plot is driven entirely by internal forces, fueled by inherited trauma and cyclical vengeance.

The novel’s narrative structure further reinforces this dark integrity, as Lockwood’s two visits to Wuthering Heights frame the story in a perfect circle. His initial visit, marked by the ghostly encounter with Catherine Earnshaw and his subsequent illness, paves the way for Nelly Dean’s account of the novel’s history. His return at the end, where he witnesses the tentative reconciliation between Cathy and Hareton and hears local gossip about Heathcliff and Catherine’s ghosts wandering the moors, brings the narrative full circle. This structural symmetry not only delivers narrative closure but also underscores the self-contained nature of the novel’s universe. Opening and concluding in the same setting, steeped in the same haunting atmosphere, the story confirms that the dark integrity of Wuthering Heights is not a product of divine order, but of a self-perpetuating cycle of love and hate operating independently of the external world. In this sense, Brontë reinterprets Aquinas’s integritas: the novel’s wholeness consists not in harmony or perfection, but in the unbroken, unsettling coherence of its dark, self-contained universe.

3.2 Perverse proportion from Brontë’s Recontextualization

For Aquinas, consonantia denotes the harmonious and rational ordering of parts within an integrated whole, signifying that the constituent elements of a totality must be arranged in a rationally calibrated and balanced order that accords with the dictates of the intellect. Aquinas believes that proportion agrees with the Son’s property, inasmuch as He is the express Image of the Father. Hence, we see that an image is said to be beautiful if it perfectly represents even an ugly thing (Aquinas, 1947). In his philosophical framework, this principle of proportion is not merely a formal aesthetic attribute but an ontological reflection of the divine reason that ordains the cosmic order. It embodies a rational symmetry that ensures each component fulfills its teleological function in service of the whole’s good—whether in the structural logic of architecture, the compositional coherence of poetry, or the normative order of civil society. In this ontological sense, consonantia is inherently inextricably linked to rationality and moderation, as it eschews excess and disequilibrium in pursuit of a harmonious equipoise of being.

Wuthering Heights does not conform to Aquinas’s rational proportion but reconstructs a deformed counterpart to consonantia, which is grounded in stark binary oppositions and generational Gothic symmetry. The novel is structured around a series of stark binary antitheses that defy all forms of rational order: the wild, untamed moors set against the cultivated, civilized grounds of Thrushcross Grange; the passionate, untrammeled love between Catherine and Heathcliff against the mild, conventional affection binding Edgar and Catherine; and Heathcliff’s raw, visceral animosity juxtaposed with the passive, resigned suffering of Hindley and Linton. These antitheses forge a narrative perpetually teetering on the precipice of chaos, as the antithetical forces of nature and civilization, passion and reason, love and hatred collide with cataclysmic force. Yet beneath this ostensible imbalance inheres a Gothic symmetry that endows the novel with a perverse sense of proportion, which is a cruel propriety that transmutes existential chaos into a terrifyingly codified aesthetic experience.

This Gothic symmetry is most salient in the novel’s generational mirroring, whereby the younger generation recapitulates and reinterprets the ontological conflicts of the older. The christening of the younger Catherine for her mother and the younger Linton for his father instantiates a mirror effect, with the children’s life trajectories echoing the familial and romantic struggles of their parental forebears. The elder Catherine’s existential choice between Heathcliff and Edgar is refracted in the younger Catherine’s coerced marriage to Linton Heathcliff and her eventual affective bond with Hareton Earnshaw. Similarly, the triangular relational dynamic of the older generation—Catherine, Heathcliff, and Edgar—is replicated in the younger generation’s triad of Cathy, Linton, and Hareton. This generational symmetry is no mere narrative trope; it constitutes a structural proportion that transmutes the novel’s ostensible imbalance into a coherent, albeit morally repugnant, order. The excesses and moral transgressions of the older generation are mirrored in the younger, forging an ineluctable and symmetrically structured cycle of intergenerational suffering.

Furthermore, the novel’s Gothic symmetry is instantiated in its dialectical balance of destruction and redemption, violence and tenderness. Heathcliff’s brutal acts of retributive vengeance are counterpoised by his profound, almost transcendent, love for Catherine Earnshaw; the eventual redemptive reconciliation between Hareton and Catherine Linton offsets his systematic cruelty toward Hareton. This dialectical balance is not the rational equipoise espoused by Aquinas, but a Gothic proportion that subsists on the sustained tension of antithetical forces and stark contrast. The novel’s most thematically resonant moments emerge from this existential tension: Catherine’s passionate ontological declaration that “I am Heathcliff” (Brontë, 2012) is counterbalanced by the quiet, redemptive tableau of Cathy and Hareton reading in communion by the fire; the violent tempest that accompanies Heathcliff’s return to the moors is juxtaposed with the serene, moonlit night when his spectral form is said to wander the heath.

In this manner, Brontë reconstructs Aquinas’s notion of consonantia: the novel’s governing proportion is not rooted in rational order or moderate equilibrium, but in the eye of the storm at its narrative core, a locus of calm, crystalline, and unflinchingly brutal order. This constitutes the novel’s perverse proportion: a symmetry that frames and amplifies human agony, rendering it not merely a shocking spectacle of suffering, but a profoundly and indelibly patterned aesthetic and ontological experience.

3.3 The Secularized Radiance of Claritas

The third element of Aquinas’s aesthetic theory, claritas, is perhaps the most profound and elusive. Derived from the Latin word for “clarity” or “radiance”, claritas refers to the luminous quality of a beautiful object that reveals its inherent essence. For Aquinas, this radiance is a reflection of the divine light, the same light that illuminates the universe and reveals the truth of God’s creation. Claritas is not a superficial brightness, but a spiritual luminosity that allows the observer to perceive the essential form of the object, whether it be a work of art, a person, or a natural phenomenon. It is the light of truth, the glow of goodness, and the radiance of beauty all in one.

In Wuthering Heights, Brontë carries out a secular reconstruction of the spiritual illumination implied in Aquinas’s claritas, replacing divine radiance with a dark, visceral glow that reveals unvarnished truths of human nature and the natural world—The novel’s claritas is not a heavenly light, but a phosphorescent glow that shines through the darkness and reveals the essence of love, hate, passion, and despair without the veil of divine order or rational moderation. This secularized radiance manifests itself in three distinct, yet interconnected, forms: the absolute light of Catherine and Heathcliff’s symbiotic love, the primal light of the moors, and the redemptive light of the novel’s quiet, hopeful ending.

The most powerful manifestation of this dark radiance is the absolute light of Catherine and Heathcliff’s love, a love that transcends the boundaries of self and other, life and death. Catherine’s declaration that “I am Heathcliff” is not merely a romantic sentiment; it is a revelation of the essential unity of their beings, a radiance that cuts through the social and psychological barriers that seek to separate them. Their love is not a conventional, rational affection, but a primal, almost animalistic bond that is both destructive and redemptive. It is a love that burns with the intensity of a wildfire, consuming everything in its path—their individual identities, social lives, and physical bodies. Yet, it is precisely this destructiveness that reveals the essential truth of love in Wuthering Heights: it is a force of nature, unyielding and absolute, that defies all social norms and rational expectations. This is the claritas of Wuthering Heights: a dark radiance that reveals the essence of human passion in its purest, most unadulterated form.

Another manifestation of Wuthering Heights’s secularized claritas is the primal light of the moors. The wild, untamable landscape serves as the backdrop for the novel’s drama. The moors are not a passive setting; they are an active, living force embodying the same primal energy as Catherine and Heathcliff’s love. Their desolate beauty, their harsh winds and their endless expanses of heather and stone all radiate a primal light that reveals the essence of the natural world: it is wild, indifferent, and infinitely powerful. The moors are a place where the boundaries between civilization and nature, life and death, self and other blur, and it is in this blurring that their claritas shines through. They are a mirror for the characters’ inner lives, reflecting their wild passions and their existential despair. The moors’ radiance is not a gentle glow, but a harsh, uncompromising light that reveals the raw, unvarnished truth of the natural world that is both beautiful and terrifying.

The final manifestation of the novel’s dark claritas is the redemptive light of the ending that emerges from the ashes of destruction, with the tranquil hope. In the final chapter of the novel, upon witnessing the infatuated Cathy and Hareton, Heathcliff sees a reflection of his younger self and Catherine. Gradually, the hatred in his heart fades and gives way to love. No longer can he bring himself to seek revenge or rob the young couple of their happiness. He ultimately abandons his vengeful quest and passes away on a stormy night, departing for the afterlife to be reunited with his beloved (Fu & Bai, 2010). After Heathcliff’s death, Cathy and Hareton find a tentative reconciliation in the ruins of Wuthering Heights, reading together by the fire and planning a future that is free from the cycle of revenge and suffering. Meanwhile, the local villagers whisper about the ghosts of Heathcliff and Catherine, wandering the moors together at night. This ending is not a conventional happy ending, nor is it a bleak, nihilistic conclusion. It is a moment of redemptive radiance that reveals the essential truth of human nature that even in the darkest of times, there is the possibility of renewal and hope. The soft, gentle light from the dancing fireplace flames the shared reading episode, and the quiet bond between Cathy and Hareton forms a sharp contrast with the wild, destructive fire of Catherine and Heathcliff’s love. This is the secularized claritas of Wuthering Heights: a light that emerges from the darkness, revealing the essence of human resilience and the possibility of redemption without the intervention of the divine.

In redefining Aquinas’s claritas as a secular, dark radiance, Brontë transforms the concept of beauty from a transcendent, divine ideal into a visceral, human experience. The novel’s claritas is not a reflection of God’s glory, but a reflection of the raw, unvarnished truths of human nature and the natural world. Such is the radiance that shines through the darkness, revealing the essence of what it means to be human.

As previously noted, Wuthering Heights does not reject Aquinas’s tripartite theory of beauty; instead, it reverses and reconstructs it, embedding integritas, consonantia, and claritas within a dark, Gothic narrative universe. The novel’s integrity is found not in divine harmony, but in the self-contained, circular logic of its characters’ passions and vendettas; its proportion is found not in rational order, but in the Gothic symmetry of extreme opposites; its radiance is found not in divine light, but in the secular, visceral glow of human passion, natural wildness, and redemptive hope. In doing so, Brontë creates a unique aesthetic system that challenges the traditional boundaries of beauty, offering a haunting, powerful vision of what it means to find beauty in the darkness.

4 Transcendence and Verification: Wuthering Heights’ Inverse Expansion of Thomistic Aesthetics

Thomas Aquinas’s aesthetic system, rooted in scholastic philosophy, posits an intrinsic yet distinct connection between beauty and goodness. He also distinguishes between “the good” and “the beautiful”: the good is the object of desire, since people seek to possess it, whereas the beautiful is the object of cognition, while the beautiful is the object of perceptiontion, as we gain pleasure merely by contemplating and understanding it. Therefore, he believes aesthetic contemplation to be a rational cognitive act and attributes the radiance of beauty to the divine light of God. These core propositions frame beauty as an orderly, morally aligned, and theocentric existence. Wuthering Heights, however, breaks through these normative aesthetic boundaries with its profound depiction of darkness, not only verifying the flexibility of Aquinas’s aesthetic framework but also realizing an inverse expansion of its theoretical connotations, enriching the connotations of Thomistic aesthetics by interpreting the dark beauty that deviates from traditional harmony and moral goodness.

Aquinas argues that beauty and goodness are correlative yet not identical: goodness is oriented toward the will and moral practice, while beauty is directed at the intellect and aesthetic perception, a distinction that implies the relative independence of beauty from moral goodness. Wuthering Heights materializes this theoretical possibility with its vivid portrayal of the beauty of evil, thus completing the practical separation of beauty and goodness in Aquinas’s theory. Heathcliff’s revenge, as the narrative core of the novel, is a violent act filled with hatred, cruelty, and moral transgression: he manipulates the lives of the Lintons and Earnshaws, distorts human nature with resentment, and turns the Yorkshire moors into a stage of pain and destruction. Yet this revenge is not a mere display of evil; it is endowed with a unique aesthetic charm that is rooted in an unswerving love for Catherine, a fierce resistance to class oppression and emotional betrayal, and a tragic grandeur of defying the world with a single will. Heathcliff’s revenge is aesthetically compelling not because of its moral value, but because of its emotional intensity, narrative tension, and the wholeness of its character logic. This portrayal confirms Aquinas’s implicit proposition that beauty can exist independently of moral goodness: the aesthetic value of a literary work or image does not depend on its adherence to moral norms, and the dark and evil can possess aesthetic significance as long as it conforms to the formal and perceptual characteristics that arouse intellectual appreciation.

Aquinas defines aesthetic contemplation as a rational cognitive endeavor in which the intellect apprehends the wholeness, proportion, and radiance of the beautiful object, bringing about peaceful and joyful aesthetic pleasure. Wuthering Heights extends this connotation of aesthetic contemplation by creating a painful and shocking aesthetic experience for readers, proving that rational cognitive pleasure is not the only form of aesthetic enjoyment, and that profound cognitive gains from emotional shock can also constitute a higher-level aesthetic experience. Reading the novel, readers are not immersed in the peaceful contemplation of harmonious beauty; instead, they are confronted with the extremes of human nature: unbridled love, boundless hatred, the distortion of desire, and the tragedy of fate. The moors’ desolation, the characters’ twisted emotions, and the tragic ending bring intense pain and mental shock, yet this shock is not a negation of aesthetic experience; on the contrary, it compels readers to conduct in-depth rational reflection on human nature, emotion, and social reality, to recognize the complexity and multifacetedness of human existence beyond the moral binary of good and evil. This rational cognition of human nature’s limits, derived from painful experience, is an extension of Aquinas’s rational aesthetic contemplation: it enriches the form of aesthetic pleasure, making the aesthetic experience no longer limited to peaceful appreciation but inclusive of the profound joy of cognitive enlightenment brought by emotional shock.

A central tenet of Thomistic aesthetics is that the radiance (claritas), which is the most essential attribute of beauty and originates from the divine light of God, the ultimate source of all beauty in the world. Wuthering Heights realizes a secular shift of the root of radiance, replacing the “divine sacred radiance” with the “wild power of nature”, and constructing a secular aesthetic view of radiance that is rooted in the earthly world. In the novel, the Yorkshire moors are not a mere setting, but a symbolic entity endowed with spiritual power: its boundless desolation, violent storms, and unbridled wildness constitute the core spiritual tone of the work, and it is the source of the radiance of the novel’s dark beauty. The wild power of nature endows Heathcliff and Catherine’s love with a fiery, unconstrained character, gives the dark narrative a primitive and grand aesthetic temperament, and becomes the perceptual carrier of the work’s beauty. This shift from the divine to the natural does not negate Aquinas’s concept of radiance, but reinterprets its source: it proves that radiance is not exclusive to the divine, and that the wild, secular natural power can also generate the unique radiance of beauty, making Thomistic aesthetics break away from theocentric constraints and adapt to the interpretation of secular aesthetic phenomena.

Ultimately, Wuthering Heights’ interpretation of dark beauty serves as a powerful verification of the inclusiveness of Aquinas’s aesthetic framework. For a long time, Thomistic aesthetics has been regarded as a theoretical tool for interpreting traditional harmonious beauty, for its emphasis on wholeness, proportion, and radiance seems to fit the aesthetic connotations of order, balance, and moral goodness. Yet the novel’s dark beauty, with its subversion of moral order, its break from traditional proportional harmony, and its secularization of radiance, can still be effectively interpreted and justified within Aquinas’s aesthetic system: the beauty of evil verifies the independence of beauty from goodness, the painful aesthetic experience extends the connotation of rational contemplation, and the natural wild radiance reinterprets the source of claritas. All these facts demonstrate that Aquinas’s aesthetic framework is not a rigid normative system that only accommodates conventional beauty, but a flexible and inclusive theoretical system that can embrace subversive, unconventional dark beauty. By expanding the application boundary of Thomistic aesthetics to the field of dark beauty, Wuthering Heights not only reveals the profound artistic value of dark beauty but also endows Aquinas’s ancient aesthetic theory with new contemporary vitality, proving its enduring theoretical value in interpreting diverse aesthetic phenomena.

5 Conclusion

This study has undertaken a rigorous examination of the manifestations and theoretical implications of dark beauty within Emily Brontë’s Wuthering Heights, employing the conceptual framework of Thomistic aesthetics as its primary analytical lens. This study argues that the novel does not merely reject or oppose Aquinas’s aesthetic system; instead, it enters a profound dialectical exchange with that through a sophisticated process of inverse construction and creative subversion. The dark beauty that permeates the text, which is conceptually anchored in the beauty of evil, experientially mediated through pain and fascination, and symbolically embodied in a wild, untamed natural clarity. It is thereby revealed not as an aberration from classical aesthetic principles, but as a radical and inventive reconfiguration of their very core tenets. This reconfiguration forces a re-evaluation of Aquinas’s thought, demonstrating its inherent capacity to accommodate and illuminate even the most disruptive of aesthetic phenomena.

At the heart of this dark aesthetic system lies the potent and troubling concept of the beauty of evil, most vividly incarnated in the figure of Heathcliff and his all-consuming passion for Catherine Earnshaw. His love transcends, or more accurately, demolishes conventional moral boundaries, spurns rational moderation, and pursues its object with a relentless, often vengeful, intensity that ultimately proves destructive to himself and all around him. Yet, within the economy of the novel’s aesthetic logic, this very destructiveness generates a perverse allure. The beauty here does not reside in moral goodness or virtuous action, but in the sheer, unmediated authenticity and overwhelming power of primal, unchecked emotion. Heathcliff’s monomaniacal fixation and revenge achieve a kind of terrible integrity, a perverted integritas that commands a horrified yet riveted attention. This constitutes a direct challenge to the Thomistic unity of the “good” and the “beautiful”, asserting instead a stark autonomy for the beautiful, which can emerge from, and even be amplified by, that which is ethically reprehensible. The painful aesthetic experience of the reader is the direct corollary to this core. Confronted with the spectacle of the lovers’ intertwined and catastrophic fates, the reader is subjected to a complex emotional response where profound sorrow, moral revulsion, and existential shock are inextricably intertwined with a powerful sense of narrative captivation and tragic awe. This experience complicates the Thomistic notion of aesthetic contemplation as a rational cognitive act, expanding it to include the paradoxical pleasure derived from witnessing artfully rendered suffering and spiritual decay, which is a pleasure rooted in the cathartic acknowledgment of life’s most extreme emotional and existential potentials.

Furthermore, the novel systematically reinterprets the Thomistic principle of claritas, or radiance. In Aquinas’s theology, claritas often implies the luminous manifestation of form, order, and divine intelligibility. In Wuthering Heights, this radiance is secularized, internalized, and made wild. It finds its primary carrier not in divine light or harmonious proportion, but in the bleak, imposing landscape of the Yorkshire moors, the ferocity of its storms, and the decaying, oppressive architecture of the Heights itself. These elements are far more than mere Gothic backdrop or pathetic fallacy; they function as the tangible, symbolic embodiments of the novel’s animating spiritual forces. The moors, with their savage freedom and indifferent endurance, radiate the same untamed, anarchic energy that drives Heathcliff. The storm mirrors the emotional tumult within. The decaying manor house physically manifests the moral and psychic corrosion of its inhabitants. This environment possesses its own fierce and forbidding radiance, which a dark glow illuminates not divine truth, but the turbulent, often destructive truths of human nature and elemental existence. It represents a radical reinterpretation of radiance as an emanation of wild, pre-moral, natural power.

The broader academic significance of this interpretive maneuver is twofold, impacting both the field of aesthetic theory and the practice of Gothic literary criticism. First and foremost, it constitutes a significant expansion of the applied scope of Thomistic aesthetics. Traditionally relegated to the analysis of works embodying classical harmony, theological order, or serene formal balance, Aquinas’s concepts are here shown to possess a remarkable elasticity. By demonstrating their capacity to provide a coherent and penetrating analysis of a text so centrally concerned with chaos, transgression, and sublimity, this study argues for the continued vitality and adaptable explanatory power of classical frameworks in the face of modern aesthetic concerns. It rescues Thomistic thought from potential antiquarian pigeonholing and asserts its relevance to a far wider spectrum of literary expression, including the deliberately anti-classical. Subsequently, it offers a vital and underutilized theoretical pathway for Gothic studies. While psychoanalytic, Marxist, feminist, and cultural-materialist approaches have yielded rich insights into the genre, a sustained philosophical-aesthetic inquiry grounded in pre-modern systems of thought remains relatively rare. This study provides precisely such an approach, opening a dialogue between Gothic literature’s preoccupation with the dark, the irrational, and the extreme, and the systematic rationality of scholastic aesthetic theory. The friction generated by this dialogue produces new insights, suggesting that the “darkness” of Gothic can be read not only as a symptom of cultural anxiety or psychological depth but also as a legitimate, structured aesthetic category within a broader historical conversation about the nature of beauty itself.

In the final analysis, it must be acknowledged that this investigation, by its focused nature, is necessarily limited in scope. Its conclusions are drawn from a deep reading of a single, albeit paramount, Gothic text. The promising implications of this fusion of Thomistic aesthetics and dark beauty naturally invite broader application and testing. Subsequent research should, therefore, embark on a program of comparative analysis. Also, it could apply the same analytical framework to other cornerstone texts of the Gothic canon, such as Mary Shelley’s Frankenstein and Bram Stoker’s Dracula. The goal would be to ascertain whether the interpretive relationship established here is singular to Brontë’s unique vision or whether it reveals a stable, generalizable critical tool for analyzing the core aesthetic strategies of the genre. Does the Creature’s pathetic yet terrifying existence, or Dracula’s aristocratic corruption, articulate their own forms of dark integrity, painful contemplation, and monstrous clarity? Such a study would serve to construct a more robust, multi-perspectival theoretical foundation for the academic study of dark beauty in literature. Through these future endeavors, the initial synthesis proposed here can be validated, refined, and integrated into a richer understanding of both the enduring power of Gothic fiction and the surprising adaptability of classical aesthetic thought.
