All liberals start off from the principle that liberty is the primary political value. After this, liberalism fractures along a spectrum of views: positive, negative and republican liberty. These are fundamentally to do with differing conceptions of liberty.
i) Humans are in a perfect state of freedom to order their actions (Locke); the burden of proof is on those who are against liberty, the a priori assumption is in favour of freedom (Mill); contemporary liberal thinkers (Feinberg, Benn and Rawls) agree.
Basic normative assumption = those who would limit freedom are under the onus of justification, particularly if they would limit freedom through coercive means
§ Political authority, its laws and policies, must be justified because they limit human freedom
– Social contract theory (Hobbes, Rousseau, Kant and Locke) is usually viewed as liberal even though the political prescriptions of each thinker have distinctly illiberal features. Nevertheless, all take as their starting point a state of nature in which humans are free and equal and so argue that the limitations imposed must be justified in terms of the social contract theory § expresses the fundamental liberal principle
ii) In addition to the fundamental liberal principle, paradigmatic liberals such as Locke argue that justified limitations on liberty are fairly modest i.e. only a limited amount of government can be justified because the basic task of the government is to protect the equal liberty of the citizens.
Disagreement about the concept of liberty has led to different conceptions of the task of government. Isaiah Berlin, for example, advocated for a negative conception of liberty:
‘If I am prevented by others from doing what I could otherwise do, I am to that degree unfree; and if this area is contracted by other men beyond a certain minimum, I can be described as being coerced, or, it may be, enslaved. Coercion is not, however, a term that covers every form of inability…Coercion implies the deliberate interference of other human beings within the area in which I could otherwise act. You lack political liberty or freedom only if you are prevented from attaining a goal by other human beings’.
§ Liberty = the absence of coercion by other human beings. The government’s role is to ensure that citizens do not coerce each other without justification in order to protect liberty. Negative liberty is an opportunity concept: being free is a matter of what we can do, regardless of whether or not we actually do it.
British neo-Hegelians such as Thomas Hill Green and Bernard Bosanquet developed a positive conception of liberty that acknowledges freedom as the exemption from compulsion by another. However, the other might not be human; someone can be unfree if he is subject to an impulse that cannot be controlled. Thus a person is only free if he is autonomous. In the sense that a free person’s actions are said to be his own, positive liberty is an exercise concept.
§ Freedom consists in the degree to which a subject has effectively determined and shaped his own life, apart from compulsions and unreflectively following customs, to the overall benefit of his short and long term interests.
As well as this concept of freedom as autonomy being present in Rousseau, Kant and Mill, contemporary theorists such as Benn, Dworkin and Raz also enshrine this liberal principle in their political theories.
Another concept of positive freedom is freedom understood as the ability to act on or pursue one’s own ends; freedom is ‘the ability act’ (Tawney). Positive freedom as effective power to act closely ties freedom to access to material resources: I cannot become a member of a Country Club because I am too poor to afford the membership though in principle I could become a member if this resource was available to me.
In the Roman, republican usage (Cicero and Machiavelli), the opposite of the liber was the servus and so the dominant connotation of freedom was not having to live in servitude to another § freedom is the opposite of domination. The ideal government ensures that no agent, including itself, has arbitrary power over any citizen, in order to ensure that every citizen’s liberty is protected. The method by which this principle is enacted is equal disbursement of power; by according each citizen power, this offsets the power of another citizen to arbitrarily interfere with his or her activities.
Unlike positive liberty, republican liberty is not primarily concerned with rational autonomy, realising one’s true nature or becoming one’s higher self.
Unlike negative liberty, republican liberty traces the mere possibility of arbitrary interference to a limitation of liberty, rather than the actual occurrence of interference.
As well as fracturing over the conception of liberty, a more important division concerns the place of private property and the market order.
Classical liberals insist upon the close relation between liberty and private property for it is through the ownership of private property that a citizen is able to live her life as she sees fit. Thus, private property is consistent with individual liberty. Some people (Gaus, Steiner, Robbins) argue that liberty and property are the same thing thus a market order based on private property is the embodiment of freedom. A secondary argument from classical liberals claims that ownership of private property is the only effective means of protecting liberty, because the individual is protected from encroachments by the state.
Even within classical liberalism there is a spectrum of views on the relationship of private property to a free society, ranging from near anarchists to left leaning views that allow for a modest social minimum. Although today classical liberalism is portrayed as extreme libertarianism, the tradition’s central concern was bettering the lot of the working class. As Bentham put it, the aim was to make the poor richer, not the rich poorer. As such, liberals reject redistribution of wealth as a legitimate aim of government.
New liberalism challenges the link between private property and individual freedom. New liberalism emerged out of a period in which the sustainability of a prosperous equilibrium was being questioned (c. late 19th/early 20th century). At the same time as losing faith in the old market order, faith was increasing in the government as a means of supervising economic life partly due to the First World War and partly due to more sophisticated democratisation in Western countries. For the first time, elected officials could truly be representatives of the community, or so it was thought. Thirdly, the growing conviction that property rights generated an unequal society to the detriment of the working class’ liberty. The first suggestion of this is found in Mill, later developed by Rawls, both of whom believed that it is an open question whether personal liberty can flourish without private property.
New liberalism is deeply concerned with developing a theory of social justice, a consequence of the impact of Rawls’ A Theory of Justice, published in 1971. Rawls’s ‘difference principle’ claims that a just basic structure of society arranges social and economic inequalities so that they are to the greatest advantage of the least well off group in a particular society. For Rawls, only inequalities that enhance the long term prospects for the least well off are just. The difference principle constitutes the principle of reciprocity, whereby no group of people is allowed to advance at the cost of another. In contemporary political thought, followers of Rawls are committed to cashing out the difference principle in terms of equality (Dworkin) hence the development from ‘welfare state’ liberalism to ‘egalitarian’ liberalism.
