Preface Luciano Floridi The information revolution has changed the world profoundly, irreversibly and problematically, at a pace and with a scope never seen before. It has provided a wealth of extremely powerful tools and methodologies, created entirely new realities and made possible unprecedented phenomena and experiences. It has caused a wide range of unique problems and conceptual issues, and opened up endless possibilities hitherto unimaginable. It has also deeply affected what philosophers do, how they think about their problems, what problems they consider worth their attention, how they conceptualise their views, and even the vocabulary they use (see Bynum and Moor 1998 and 2002, Colburn 2000, Floridi 1999, and Mitcham and Huning 1986 for references). The information revolution has made possible fresh approaches and original investigations. It has posed or helped to identify new crucial questions and given new meaning to classic problems and traditional topics. In short, information- theoretic and computational research in philosophy has become increasingly innovative, fertile, and pervasive. It has already produced a wealth of interesting and important results. This Guide is the first attempt to map systematically this new and vitally important area of research. Owing to the novelty of the field, it is an exploration as much as an introduction. As an introduction, the twenty-six chapters in this volume seek to provide a critical survey of the fundamental themes, problems, arguments, theories and methodologies constituting the new field of philosophy of computing and information (PCI). The chapters are organised into eight sections. The introductory chapter offers an interpretation of the new informational paradigm in philosophy and prepares the ground for the following chapters. The project for the Guide was based on the hermeneutical frame outlined in that chapter, but the reader may wish to keep in mind that I am the only person responsible for the views expressed there. Other contributors in this Guide may not share the same perspective. In the second section, four of the most crucial concepts in PCI, namely computation, complexity , system, and information are analysed. They are the four columns on which the other chapters are built, as it were. The following six sections are dedicated to specific areas: the information society (computer ethics; communication and interaction; cyberphilosophy and internet culture; and digital art); mind and intelligence
