This thesis is mainly interested in the relationship between the instruments of value and methods to promote them envisaged in liberal freedom and green moral and political theories. Liberalism is explored. Neither neutrality, nor individualism, nor privacy can fully account for liberalism.
Freedom is of much more importance to liberalism.
Social freedom is analysed. MacCallum's triadic formulation is refined, adding the factor of a description of the constrainer. This 'tetradic' formulation aids distinguishing impossibilities from unfreedoms. Quantification of freedom is explored. For freedom quantity and value are closely bound, with value largely determined by the value of the aim.
