This review traces the correspondence between the main purpose of Bloomsbury’s Series Theory in the New Humanities (i.e. the presentation of cartographical accounts of emerging critical theories), and Francesca Ferrando’s book, with its combination of genealogical-cartographic approach and critical response in contributing philosophical posthumanism. The review also highlights the value of Ferrando’s work, both on the theoretical-scientific-didactic level and on that of existential praxis. Through a critical recognition of the book’s thematic joints (defining philosophical posthumanism, determining what is meant by “post”, questioning whether humans have always been posthuman) and of the main contents, the review explores the work’s pioneering aspects, including its original structure, scientific rigor, and historical reconstruction through a critical mastery of sources, and praises Ferrando’s enthusiastic proposal of a posthumanism as the philosophy/praxis of our time.
