Book excerpt: This book provides new theoretical approaches to the subject of virtuality. All chapters reflect the importance of extending the analysis of the concept of “the virtual” to areas of knowledge that, until today, have not been fully included in its philosophical foundations. The respective chapters share new insights on art, media, psychic systems and technology, while also presenting new ways of articulating the concept of the virtual with regard to the main premises of Western thought. Given its thematic scope, this book is intended not only for a philosophical audience, but also for all scientists who have turned to the humanities in search of answers to their questions.
