Jack London's The Call of the Wild is a multifaceted work that has captivated audiences since its publication in 1903. Through the tale of Buck, a domesticated dog thrust into the wilds of the Klondike, London explores themes of survival, the clash between civilization and nature, and the inherent duality in both animal and human nature. These themes are woven with strands of Darwinian theory, Nietzschean philosophy, and Marxist socialism, making the novel a rich tapestry of ideas that continue to engage scholars and readers alike.

Animals as Protagonists

Jack London’s literary legacy is largely defined by his ability to turn animals into compelling protagonists, as demonstrated in works like The Call of the Wild, White Fang, and Jerry of the Islands. His portrayal of animals as characters equal to human beings goes beyond anthropomorphism to explore deeper philosophical questions. Rather than merely personifying animals, London's stories emphasize the evolutionary connections between humans and animals, resisting the sentimental fables prevalent during his time. His narratives reflect substantial scientific and philosophical themes, particularly influenced by Charles Darwin and Friedrich Nietzsche.

Darwinian and Nietzschean Influences

In The Call of the Wild, London's depiction of Buck's transformation is steeped in Darwinian and Nietzschean philosophy. Buck's journey from a pampered pet to a creature of the wild illustrates the "survival of the fittest" concept, as Buck learns to adapt to the harsh realities of the Northland through strength and intelligence. This transformation is akin to Nietzsche’s idea of the Übermensch, where Buck embodies superior qualities, both mentally and physically, compared to the other dogs. Despite these raw encounters with nature, Buck’s time with John Thornton shows the tension between the civilized and the primal aspects of his being, highlighting the delicate balance between instinct and learned behavior.

The Dual Nature of Existence

London's narrative delves into the duality of Buck's nature, which mirrors the inherent conflict within all human beings. Buck's experiences suggest that there is a primitive, instinctual part lurking beneath the surface of civilization. The novel intimates that while animals like Buck can fully embrace this primitive side, humans must navigate a more complex relationship between their civilized selves and their primal instincts. London elucidates this theme in other works such as The Sea-Wolf, where he posits that a balance between the brutish and the civilized is essential for human existence.

Socialist Undertones

Another layer of complexity is added when considering London's socialist leanings. Through a Marxist lens, Buck can be seen as an oppressed character, subjected to the whims of his masters and their exploitation of power. Buck's evolution from a creature of survival to one capable of cooperation under Thornton’s equitable guidance reflects a shift from Darwinian individualism to a more socialist cooperation. This duality highlights London’s belief in the potential for a more equitable society, where oppressive power is replaced with communal productivity and cooperation.

Critical Reception and Allegorical Interpretations

Upon its release, The Call of the Wild was celebrated as an invigorating alternative to the fiction of its era. Critics lauded its depth and the "eternal principles" it conveyed, despite acknowledging its often relentless storytelling. Abroad, London was viewed as a preeminent American writer, although initially, his work was undervalued in the United States, relegated to children's literature and escapist fiction. However, since the 1960s, a resurgence in scholarly interest has helped reestablish London as a critical figure in American literature, with The Call of the Wild being at the forefront of this renewed appreciation.

Autobiographical and Allegorical Elements

Critics frequently explore the autobiographical and allegorical dimensions of London's work. Joan Hedrick suggests that through Buck, London revisits his working-class past and imagines a new future. Andrew Flink draws parallels between London’s personal experiences, such as his time in prison, and Buck's trials in the Klondike. The novel is often interpreted as an allegory for societal struggles, where the harshness of the wild parallels the brutality of human society, challenging the distinction between human and animal existence.

Naturalism and Romantic Primitivism

The novel is also examined through the lens of literary naturalism and romantic primitivism. Some scholars, like Mary Kay Dodson, see it as a quintessential example of naturalism, while others, including Earl J. Wilcox, argue that its naturalistic elements are inconsistent. Jonathan Auerbach underscores the narrative’s complex duality, which navigates between themes of decivilization and self-transcendence, resisting a purely naturalistic interpretation. Charles N. Watson, Jr., posits that this tension between naturalism and romantic primitivism is central to the novel’s enduring appeal, highlighting the dual thematic currents that American fiction often explores.

Ultimately, the contradictions and complexities within The Call of the Wild are what continue to fascinate audiences and scholars. London's masterful weaving of philosophical, social, and personal themes into a gripping narrative ensures the novel's place as a beloved and essential piece of American literature.
