This book offers a conceptual framework for understanding risk, drawing on fifty years of sociology and philosophical modernity to explore key concepts such as uncertainty, danger, and threat. Stefan Popov applies this framework to risk reduction policies, emphasizing the role of deliberative decision-making in liberal democratic societies.In so doing, Popov presents risk as a political phenomenon, highlighting its structural features through the lens of Kant’s aesthetic judgement and its reconstruction in Hannah Arendt’s political philosophy.
