 Gaus (2004) argues that the distinction between ‘political’ and ‘comprehensive’ liberalism misses a great deal. Liberal theories form a broad continuum, from those that constitute full-blown philosophical systems, to those that rely on a full theory of value and the good, to those that rely on a theory of the right (but not the good), all the way to those that seek to be purely political doctrines. Nevertheless, it is important to appreciate that, though we treat liberalism as primarily a political theory, it has been associated with broader theories of ethics, value, and society. Indeed, many believe that liberalism cannot rid itself of all controversial metaphysical (Hampton, 1989) or epistemological (Raz, 1990) commitments.
