Drawing on recent posthumanist theories that promote a non-anthropocentric perspective, this study examines the works of contemporary British poets Mario Petrucci and Alice Oswald. It is argued that their poetry can be described as posthuman poetry, which envisions posthuman spaces of becoming where human and nonhuman worlds coexist on a non-hierarchical basis. Petrucci’s engagement with ecocritical crises in the Anthropocene underscores the limits of human agency, and it foregrounds destructive impact of human actions on the ecosystem. In a posthuman context, therefore, Petrucci problematises the human/nonhuman binary by representing the erosion of the anthropocentric worldview in the face of environmental crises such as deforestation, global warming, and the Chernobyl nuclear disaster in Bosco (1999), Heavy Water: A Poem for Chernobyl (2004) and Half Life: Poems for Chernobyl (2004). In these collections, challenging the perception of nonhuman matter as passive, Petrucci emphasises the agency of trees and radioactive particles. Similarly, Alice Oswald moves the reader beyond the human-centred treatment of the natural world. Rejecting human exceptionalism, Oswald’s Dart (2002) presents a polyphonic meshwork where the voices of alternating human speakers and the River Dart interweave within a posthuman space. Representing the intersubjective and dialogic exchanges between the human and nonhuman inhabitants of the Severn Estuary and the lunar cycle, Oswald’s A Sleepwalk on the Severn (2009) further problematises the subject/object binary by creating a posthuman space of becoming grounded in a communicative framework. Hence, bringing Petrucci and Oswald together, this study draws attention to trans-corporeal and polyphonic entanglements of human-nonhuman, subject-object and self-other non-binaries, and it aims to show how poetry, as a literary medium, can contribute to questioning and transforming the anthropocentric vision of humankind in the contemporary world.

The aim of this book is to study William Shakespeare’s Titus Andronicus (1594), Macbeth (1606), and King Lear (1608), as examples of the state of rivalry which, as the study asserts, is related to Thomas Hobbes’ theory of the state of nature, and René Girard’s theory of mimetic desire. To this end, the state of nature, mimetic desire, and the state of rivalry are studied with their origins, definitions, types, and characteristics. The state of nature refers to the state of man who is egotistic, and self-preserving. A man in this state believes in equality by birth. In this state, man is at war against one another, as there is no (or lack of) authority to keep everyone secure. However, there may be human beings who are in that state even in a civil society under the dominion of an authority. They may secretly put manipulative plans into action for personal gains. Such an authority constructs order by the help of civil laws to prevent any disobedience and civil strife. In time of disobedience, this condition may spread around like a contagious disease. Among the reasons that lead to such a conflict, for Hobbes, are competition, diffidence, and glory. These notions have parallels with mimetic desire. Mimetic desire refers to man’s mediated desire toward an object. Imitating a mediator brings forth rivalry since the desired object ascertains competition. Therefore, mimetic desire has a triangular structure: mediator as the model, the desirer, and the desired object. The study concludes that the characteristics of, and the relationship between the state of nature, and mimetic desire are conducive to the state of rivalry in Shakespeare’s Titus Andronicus, Macbeth, and King Lear.
