Abstract

This paper argues for a non-moral interpretation of the libertarian conception of interpersonal liberty as ‘the absence of imposed cost.’ In the event of a clash of imposed costs, observing such liberty entails ‘minimising imposed costs’. Three fundamental criticisms are examined: strictly interpreted, this would logically imply genocide in practice; it is impractically unclear and moralised; it could entail mob rule of some kind. Self-ownership and private property are then non-morally derived merely from applying this formula in a state of nature. Various subsidiary issues arise throughout.
