The book is an attempt to explore the affinities between contemporary critical theories and modernist and postmodernist American poetry. The analysis focuses on poststructuralist theories, notorious for their tendency to destabilize generic boundaries between literary, philosophical and critical discourses. The main argument and the structure of the book derive from Jacques Derrida’s essay “Che cos’è la poesia” [What is poetry?] in which the philosopher postulates the impossibility of defining poetry by comparing a poem to a hedgehog – prickly, solitary, untamed, (...) fragile and protective, rolling itself up into a ball at the first sign of danger or when in the hands of the reader-intruder. The metaphor captures thus the fragility of the relationship between poetry and the world. The book examines this relationship as exemplified by the erinaceous poetics of high modernists and their postmodernist followers In the study I employ also other oststructuralist theories, such as the notion of the text and the pleasure of the text formulated by Roland Barthes, the heories of metaphor as seen by Paul Ricoeur or Paul de Man, and gender-sensitive theories of Helene Cixous and Luce Irigaray.
