Prevention, knowledge, justice: Robert Nozick and counterterrorism

This article explores questions of justice and moral permissibility of state action in counterterrorism through Robert Nozick’s Anarchy, State, and Utopia. Using the case of the Berlin attack in December of 2016 and the ensuing political debate over whether potential terrorists could be put into preventive custody as an illustrative example, it engages Nozick’s argument on prevention, knowledge and justice. In Nozick’s fierce defence of individual rights, the state comes into being as an aggregate of individuals and their inviolable rights, and thus possesses no moral legitimacy of its own. Individual rights must therefore not be violated for the sake of common goods. In conjunction with his emphasis on free will and the ensuing unpredictability of human decision-making, the article highlights the Nozickian position as a powerful account against the justification of preventive custody, thereby providing a moral “fail-safe” in counterterrorism discourses that build on just war theory and utilitarianism.
