Sam Forsythe is a Doctoral Researcher in International Security at the Peace Research Institute Frankfurt, and a member of the Research Group for the Use and Control of Emerging Disruptive Technologies in the Cluster for Natural and Technical Science Arms Control Research. Forsythe's current work explores the logic of deception in international statecraft and strategy, with an empirical focus on the history and practice of intelligence, disinformation, propaganda and cyber operations. Alongside this he works on the intellectual history of political and strategic thought. Forsythe's theoretical and philosophical work explores the role of inquiry, abduction and semiosis in strategic reasoning and adversarial rationality, applying concepts and theories from C.S. Peirce and pragmatist philosophy to practical domains and sociological problems. Recent publications include the editing of a handbook section and authoring of a chapter on ‘adversarial abduction’ (Handbook of Abductive Cognition, Springer. 2023), a chapter on disinformation and arms control (2023 Peace Report, Transcript Verlag. 2023), and a chapter on the logic of strategy in Frank Herbert’s classic sci-fi novel, Dune (Dune and Philosophy, Wiley-Blackwell. 2023).
