What is the role and value of fictions, metaphors, scenarios and figures in adjudication? This book develops three models to help answer that question: inquiry, artefacts and imagination. Legal language, it is argued, contains artefacts - forms that signal their own artifice and call upon us to do things with them and thanks to them. To imagine, in turn, is to enter into a distinctive epistemic frame where we temporarily suspend certain epistemic norms and commitments and participate actively along a spectrum of affective, sensory and kinetic involvement. The book argues that artefacts and related processes of imagination are valuable insofar as they enable inquiry in adjudication, i.e. the social (interactive and collective) process of making insight into what values, vulnerabilities and interests may be at stake in a case and in cases like it in the future. The book is structured in two parts, with the first offering an account of the three models of inquiry, artefacts and imagination, and the second examining four case studies (fictions, metaphors, figures and scenarios). Drawing on a broad range of theoretical traditions - including philosophy of imagination and emotion, the theory and history of rhetoric, and the cognitive humanities - this book offers an interdisciplinary defence of the importance of artefactual language and imagination in adjudication.
