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.

There is no form or species of literature that may not be interpreted by psychoanalytic methods. Be the author ever so objective, no matter how much he has sought to make his personality intangible and elusive, there are means, with the aid of clues, of opening up the barred gates of his soul. Men like Flaubert and Merimée, who believed in the impersonal and objective theory of art and who strove deliberately to conceal their personalities, failed in doing so. Their presence is revealed in their stories; they could not hold themselves aloof. It is true we have been aided by external evidence in learning what methods they employed to render themselves impersonal; the real Merimée and Flaubert, however, were made to emerge by the help of their published personal letters. It matters not whether the author writes realistic or romantic fiction, autobiographical or historical tales, lyric or epic poems, dramas or essays, his unconscious is there, in some degree.

But in a field which is largely new, it is best to take those works or species of writing where the existence of the unconscious does not elude our efforts to detect it. Therefore, much will be said in this volume of works where there is no question that the author is talking from his own experiences, in his own person, or where he is using some character as a vehicle for his own point of view. Such works include lyric poetry which is usually the personal expression of the love emotions of the singer. Burns, Byron, Shelley, Keats and Swinburne have left us records of their love affairs in their great lyric poems. Most of these were inspired by frustration of love, and were the results of actual experiences. And though much is said in them, other facts may be deduced.
