Circus Night "explores the survival dilemma of women in commodification, objectification, and symbolization through the framework of a homeless novel, revolving around the flying of wings on the back. Critics have analyzed the female characters in the novel from a gender political perspective, such as Rousseau's view that deformed people are landscapes in commodity trading, Yang's ecofeminist perspective that flying bodies subvert the boundaries and hierarchical systems that oppress women, and Skechers' focus on the depersonalization of female bodies in cultural symbols. Carter went beyond gender criticism and focused on post human body politics. Through depictions of deformed bodies, transgender bodies, and non-human bodies, he deconstructed the body and criticized anthropocentrism, showcasing post human body politics.

Post human body politics as a domain of physical liberation

Post human body politics explores the transformation of the human body under the influence of technology in 'Night at the Circus'. The concept of posthumanism originated from science fiction novels, referring to the synthesis of humans and machines, emphasizing that the body transcends traditional biological and material limitations. Theorists focus on the possibility of reconstructing the body, breaking through material and biological limitations, and organizing the body into domains. The political concerns of the post human body include: synthesizing the body, exploring genetic engineering and cloning technology to redefine the physiological boundaries of the body, such as cloning technology to replicate the body, and nano chip implantation to achieve human-machine integration; The informationized body, artificial intelligence, and digital technology dissolve embodiment, consciousness may be extracted or replicated from the physical body, and the body becomes the encoding of information; Cross domain body, opposing anthropocentrism, emphasizing the connection between humans, animals, and nature, and creating a cross domain body. Post human body politics has expanded the openness and possibilities of the body, and the process of deconstructing the body aims to create an open, fluid, and clustered diversified body.

Dissolve the deformed body of the human cognitive system

Explored the author's challenge and deconstruction of traditional human understanding of the body by depicting deformed bodies in 'Night at the Circus'. The characters in the novel, such as Fanny, the Wonders of Wessex, Albert/Albertina, and Fei Fei, all possess unconventional physical characteristics that question the scientific and rational definition of the body. Flying wings have become the core of the novel, as she does not seek scientific explanations, but rather attempts to break the boundary between normal and abnormal, challenging the cognitive approach of scientific rationality. Journalist Wallace represents a typical example of scientific rational cognition. He questions the authenticity of Feifei's wings through analysis of anatomy, mechanics, and biology. However, Feifei uses cultural interpretation to connect his body with the human cultural coding system, blurring the boundary between truth and falsehood. Carter questioned the body cognition category established by scientific rationality principles through his flying body, pointing out that the human cognitive system cannot cover all natural phenomena, thus forcing readers to rethink the rationality of the traditional body cognition system.

A trans body that breaks through the hierarchical order of species

Circus Night challenges the traditional hierarchical order of species through the concept of transpersonal bodies, emphasizing the material connection and interdependence between humans and animals. In the novel, the protagonist Fei Fei's transpersonal traits, such as animalistic body odor and appetite, as well as the anthropomorphic expression of animals, such as Sibyl's human cognition and the social behavior of apes, together blur the boundary between humans and animals. These cross disciplinary features not only demonstrate the commonality between humans and animals, but also question the concept of anthropocentrism and promote the exploration of post human communication ethics. Carter criticized the dominant position of humans over nature and advocated for an equal state of dialogue, redefining the relationship between humans and animals.

A non-human body that disrupts the stable structure of the body

Explored the embodiment of anthropocentrism at the physical level, including the definition of body standards and the hierarchical order between humans and animals, as well as the pursuit of human body stability and organization. The author analyzes the clown characters in "Night at the Circus" to demonstrate the fluidity and anti organizational structure of the non-human body, thereby disrupting the stability of the body. The clown constructs an ethereal body through ever-changing masks and performances, blurring the boundaries of identity and gender, and reflecting non-human traits. The clown's bodily performances, such as cutting, growing, cutting again, and growing again, symbolize the incompleteness and generativity of the body, breaking the closed and structural nature of the body. The clown's' Dance of Disintegration 'further blurs the boundary between life and death, and dissolves the physiological limitations of the body. These manifestations of non-human bodies dissolve the unity and organizational boundaries of the body, disrupt the stable structure of the body, reflect the characteristics of post humanism, and challenge the anthropocentric body cognitive system and species hierarchy order.
