Through a collection of essays, this open access book brings together perspectives on philosophy of technology and design. Taking stock of recent changes in technology – including recently emerging digital tools like AI – the authors look to expand the discussions that draw upon both design philosophy and technological developments. The editors of the book argue that we are already a long way from the conventional interpretation of design philosophy as a ‘philosophy of design’, where philosophers remained distant from the practice of design itself.They maintain that designers must welcome cross-fertilisations between disciplines that make possible alternative interpretations of design philosophy, for example, as ‘a designerly way of doing philosophy’ or as ‘designing things philosophically’, perhaps even as ‘the design of philosophy’. The book is structured in two parts: the first comprises chapters that address foundational issues arising at the crossroads of philosophy and design; the second addresses chapters that address special topics, including AI and democracy, fashion design, professional ethics, and climate engineering. The editions of this book are available open access under a CC BY 4.0 licence on bloomsburycollections.com.Open access was funded by the TU Delft Open Access Fund.
