A measure of freedom

When liberal political philosophers talk of equalizing, increasing or maximizing freedom (or liberty), they implicitly assume freedom to be a measurable attribute. Freedom is one of the currencies of a liberal theory of distributive justice, and is therefore assumed to be something that individuals can possess in varying degrees. Yet it is rarely clear what is meant by claims about degrees of freedom. To make sense of such claims, we need to clarify the concept of overall freedom and ask whether its measurement is theoretically possible. This concept is important because freedom has, for liberals, non-specific (or content-independent) value–i.e. value that is independent of the value of being free to do specific things. Liberals prescribe not only that individuals have certain specific freedom-types but also that they have a measure of (overall) freedom. Attempts to make sense of the concept of overall freedom by weighting particular options in terms of their values are erroneous, as these do not account for freedom’s non-specific value. On the other hand, a closer examination of the problems of the individuation of actions and of the various types of constraints on freedom shows overall freedom to be measurable in a way that reflects its non-specific value. To this end, actions need to be individuated in spatio-temporal terms and constraints on freedom need to be characterized in terms of the physical compossibility of actions. The comparative judgements about freedom implied by this analysis (with reference both to individuals and to groups) are more coherent with our intuitive judgements than might at first be expected.-- Introduction -- Part I Justice and Overall Freedom -- 1 The Concept of Overall Freedom -- 2 The Value of Freedom -- 3 The Distribution of Freedom -- 4 Reflective Equilibrium -- Part II Value-Based Freedom -- 5 The Value-Based Approach -- 6 Self-Mastery -- Part III Empirical Freedom -- 7 Individual Freedom: Actions -- 8 Individual Freedom: Constraints -- 9 Group Freedom -- 10 Indicators of Freedom -- ConclusionPublished version of EUI PhD thesis, 199
