Prevention, coercion, and two concepts of negative liberty

This paper argues that there are two, irreducibly distinct negative concepts of liberty: freedom as non-prevention and freedom as non-coercion. Contemporary proponents of the negative view, such as Matthew Kramer and Ian Carter, have sought to develop the Hobbesian idea that freedom is essentially a matter of physical non-prevention. Accordingly, they have sought to reduce the freedom-diminishing effect of coercion to that of prevention by arguing that coercive threats function to diminish freedom by preventing people from performing certain combinations of actions. Against this, this paper argues that coercion diminishes people’s freedom in ways that cannot be fully captured in terms of prevention. Focusing on two types of case, those involving coercive threats and those involving coercive preference manipulation, it argues that non-coercion and physical non-prevention are importantly different goods. It concludes that a complete negative account of liberty must draw not only on the (Hobbesian) ‘non-prevention’ strand of the negative tradition but also on its (Benthamite and Hayekian) ‘non-coercion’ strands
