Many liberals have been attracted to more ‘positive’ conceptions of liberty. Although Rousseau seemed to advocate a positive conception of liberty, according to which one was free when one acted according to one’s true will (the general will), the positive conception was best developed by the British neo-Hegelians of the late nineteenth and early twentieth centuries, such as Thomas Hill Green and Bernard Bosanquet . Green acknowledged that it must be of course admitted that every usage of the term to express anything but a social and political relation of one man to other involves a metaphor. It always implie some exemption from compulsion by another. Nevertheless, Green went on to claim that a person can be unfree if he is subject to an impulse or craving that cannot be controlled. Such a person, Green argued, is in the condition of a bondsman who is carrying out the will of another, not his own” . Just as a slave is not doing what he wants to do, one who is, say, an alcoholic, is being led by a craving to look for satisfaction where it cannot, ultimately, be found.
