 The concept of overall freedom appears to play an important role both in everyday discourse and in contemporary political philosophy. It is only recently, however, that philosophers have stopped concentrating exclusively on the meaning of a particular freedom — the freedom to do or become this or that particular thing — and have started asking whether we can also make sense of descriptive claims to the effect that one person or society is freer than another, or of liberal normative claims to the effect that freedom should be maximized or that people should enjoy equal freedom or that they each have a right to a certain minimum level of freedom. The literal meaningfulness of such claims depends on the possibility of gauging degrees of overall freedom, sometimes comparatively, sometimes absolutely.
