The notion of ‘the human’ is in need of urgent redefinition. At a time of radical bio-technological developments, and in light of the political and environmental imperatives of our age, the term ‘posthuman’ provides an alternative. The philosophical landscape which has developed as a response to the crisis of the human, includes several movements, such as: Posthumanism, Transhumanism, Antihumanism and Object Oriented Ontology. This book explains the similarities and differences between these currents and offers a detailed examination of a number of topics that fall under the “posthuman” umbrella, including the anthropocene, artificial intelligence and the deconstruction of the human. Francesca Ferrando affords particular focus to Philosophical Posthumanism, defined as a philosophy of mediation which addresses the meaning of humanity not in separation, but in relation to technology and ecology. The posthuman shift thus emerges in the global call for social change, responsible science and multispecies coexistence.
