Broadly speaking, liberty is the ability to do as one pleases. In modern politics, liberty is the state of being free within society from oppressive restrictions imposed by authority on one's way of life, behavior, or political views. In philosophy, liberty involves free will as contrasted with determinism. In theology, liberty is freedom from the effects of "sin, spiritual servitude, [or] worldly ties".
Sometimes liberty is differentiated from freedom by using the word "freedom" primarily, if not exclusively, to mean the ability to do as one wills and what one has the power to do; and using the word "liberty" to mean the absence of arbitrary restraints, taking into account the rights of all involved. In this sense, the exercise of liberty is subject to capability and limited by the rights of others. Thus liberty entails the responsible use of freedom under the rule of law without depriving anyone else of their freedom. Freedom is more broad in that it represents a total lack of restraint or the unrestrained ability to fulfill one's desires. For example, a person can have the freedom to murder, but not have the liberty to murder, as the latter example deprives others of their right not to be harmed. Liberty can be taken away as a form of punishment. In many countries, people can be deprived of their liberty if they are convicted of criminal acts.
Philosophers from earliest times have considered the question of liberty. Roman Emperor Marcus Aurelius (121-180 AD) wrote:
a polity in which there is the same law for all, a polity administered with regard to equal rights and equal freedom of speech, and the idea of a kingly government which respects most of all the freedom of the governed.
According to Thomas Hobbes (1588-1679):
a free man is he that in those things which by his strength and wit he is able to do is not hindered to do what he hath the will to do.-- Leviathan, Part 2, Ch. XXI.
John Locke (1632-1704) rejected that definition of liberty. While not specifically mentioning Hobbes, he attacks Sir Robert Filmer who had the same definition. According to Locke:
In the state of nature, liberty consists of being free from any superior power on Earth. People are not under the will or lawmaking authority of others but have only the law of nature for their rule. In political society, liberty consists of being under no other lawmaking power except that established by consent in the commonwealth. People are free from the dominion of any will or legal restraint apart from that enacted by their own constituted lawmaking power according to the trust put in it. Thus, freedom is not as Sir Robert Filmer defines it: 'A liberty for everyone to do what he likes, to live as he pleases, and not to be tied by any laws.' Freedom is constrained by laws in both the state of nature and political society. Freedom of nature is to be under no other restraint but the law of nature. Freedom of people under government is to be under no restraint apart from standing rules to live by that are common to everyone in the society and made by the lawmaking power established in it. Persons have a right or liberty to (1) follow their own will in all things that the law has not prohibited and (2) not be subject to the inconstant, uncertain, unknown, and arbitrary wills of others.
In his book Two Concepts of Liberty, Isaiah Berlin formally framed the differences between two perspectives as the distinction between two opposite concepts of liberty: positive liberty and negative liberty. The latter designates a negative condition in which an individual is protected from tyranny and the arbitrary exercise of authority, while the former refers to the liberty that comes from self-mastery, the freedom from inner compulsions such as weakness and fear.
The modern concept of political liberty has its origins in the Greek concepts of freedom and slavery. To be free, to the Greeks, was not to have a master, to be independent from a master (to live as one likes). That was the original Greek concept of freedom. It is closely linked with the concept of democracy, as Aristotle put it:
This applied only to free men. In Athens, for instance, women could not vote or hold office and were legally and socially dependent on a male relative.
The populations of the Persian Empire enjoyed some degree of freedom. Citizens of all religions and ethnic groups were given the same rights and had the same freedom of religion, women had the same rights as men, and slavery was abolished (550 BC). All the palaces of the kings of Persia were built by paid workers in an era when slaves typically did such work.
In the Buddhist Maurya Empire of ancient India, citizens of all religions and ethnic groups had some rights to freedom, tolerance, and equality. The need for tolerance on an egalitarian basis can be found in the Edicts of Ashoka the Great, which emphasize the importance of tolerance in public policy by the government. The slaughter or capture of prisoners of war also appears to have been condemned by Ashoka. Slavery also appears to have been non-existent in the Maurya Empire. However, according to Hermann Kulke and Dietmar Rothermund, "Ashoka's orders seem to have been resisted right from the beginning."
Roman law also embraced certain limited forms of liberty, even under the rule of the Roman Emperors. However, these liberties were accorded only to Roman citizens. Many of the liberties enjoyed under Roman law endured through the Middle Ages, but were enjoyed solely by the nobility, rarely by the common man. The idea of inalienable and universal liberties had to wait until the Age of Enlightenment.
The social contract theory, most influentially formulated by Hobbes, John Locke and Rousseau (though first suggested by Plato in The Republic), was among the first to provide a political classification of rights, in particular through the notion of sovereignty and of natural rights. The thinkers of the Enlightenment reasoned that law governed both heavenly and human affairs, and that law gave the king his power, rather than the king's power giving force to law. This conception of law would find its culmination in the ideas of Montesquieu. The conception of law as a relationship between individuals, rather than families, came to the fore, and with it the increasing focus on individual liberty as a fundamental reality, given by "Nature and Nature's God," which, in the ideal state, would be as universal as possible.
In On Liberty, John Stuart Mill sought to define the "...nature and limits of the power which can be legitimately exercised by society over the individual," and as such, he describes an inherent and continuous antagonism between liberty and authority and thus, the prevailing question becomes "how to make the fitting adjustment between individual independence and social control".
England (and, following the Act of Union 1707, Great Britain), laid down the cornerstones of the concept of individual liberty.
In 1100 the Charter of Liberties is passed which sets out certain liberties of nobles, church officials and individuals.
1187-1189 sees the publication of Tractatus de legibus et consuetudinibus regni Anglie which contains authoritative definitions of freedom and servitude:
Freedom is the natural faculty of doing what each person pleases to do according to his will, except what is prohibited to him of right or by force. Sevitude on the other hand may be said to be the contrary, as if any person contrary to freedom should be bound upon a covenant to do something, or not to do it.
In 1628 the English Parliament passed the Petition of Right which set out specific liberties of English subjects.
In 1679 the English Parliament passed the Habeas Corpus Act which outlawed unlawful or arbitrary imprisonment.
In 1772 the Somerset v Stewart judgement found that slavery was unsupported by common law in England and Wales.
In 1859 an essay by the philosopher John Stuart Mill, entitled On Liberty, argued for toleration and individuality. "If any opinion is compelled to silence, that opinion may, for aught we can certainly know, be true. To deny this is to assume our own infallibility."
In 1948 British representatives attempted to but were prevented from adding a legal framework to the Universal Declaration of Human Rights. (It was not until 1976 that the International Covenant on Civil and Political Rights came into force, giving a legal status to most of the Declaration.)
According to the 1776 United States Declaration of Independence, all men have a natural right to "life, liberty, and the pursuit of happiness". But this declaration of liberty was troubled from the outset by the institutionalization of legalized Black slavery. Slave owners argued that their liberty was paramount since it involved property, their slaves, and that Blacks had no rights that any White man was obliged to recognize. The Supreme Court, in the Dred Scott decision, upheld this principle. It was not until 1866, following the Civil War, that the US Constitution was amended to extend these rights to persons of color, and not until 1920 that these rights were extended to women.
By the later half of the 20th century, liberty was expanded further to prohibit government interference with personal choices. In the United States Supreme Court decision Griswold v. Connecticut, Justice William O. Douglas argued that liberties relating to personal relationships, such as marriage, have a unique primacy of place in the hierarchy of freedoms. Jacob M. Appel has summarized this principle:
I am grateful that I have rights in the proverbial public square - but, as a practical matter, my most cherished rights are those that I possess in my bedroom and hospital room and death chamber. Most people are far more concerned that they can control their own bodies than they are about petitioning Congress.
In modern America, various competing ideologies have divergent views about how best to promote liberty. Liberals in the original sense of the word see equality as a necessary component of freedom. Progressives stress freedom from business monopoly as essential. Libertarians disagree, and see economic freedom as best. The Tea Party movement sees the undefined "big government" as the enemy of freedom.
France supported the Americans in their revolt against English rule and, in 1789, overthrew their own monarchy, with the cry of "Liberté, égalité, fraternité". The bloodbath that followed, known as the reign of terror, soured many people on the idea of liberty. Edmund Burke, considered one of the fathers of conservatism, wrote "The French had shewn themselves the ablest architects of ruin that had hitherto existed in the world."
According to the Concise Oxford Dictionary of Politics, liberalism is "the belief that it is the aim of politics to preserve individual rights and to maximize freedom of choice". But they point out that there is considerable discussion about how to achieve those goals. Every discussion of freedom depends on three key components: who is free, what they are free to do, and what forces restrict their freedom. John Gray argues that the core belief of liberalism is toleration. Liberals allow others freedom to do what they want, in exchange for having the same freedom in return. This idea of freedom is personal rather than political. William Safire points out that liberalism is attacked by both the Right and the Left: by the Right for defending such practices as abortion, homosexuality, and atheism, and by the Left for defending free enterprise and the rights of the individual over the collective.
According to the Encyclopædia Britannica, libertarians hold liberty as their primary political value. Their approach to implementing liberty involves opposing any governmental coercion, aside from that which is necessary to prevent individuals from coercing each other.
According to republican theorists of freedom, like the historian Quentin Skinner or the philosopher Philip Pettit, one's liberty should not be viewed as the absence of interference in one's actions, but as non-domination. According to this view, which originates in the Roman Digest, to be a liber homo, a free man, means not being subject to another's arbitrary will, that is to say, dominated by another. They also cite Machiavelli who asserted that you must be a member of a free self-governing civil association, a republic, if you are to enjoy individual liberty.
The predominance of this view of liberty among parliamentarians during the English Civil War resulted in the creation of the liberal concept of freedom as non-interference in Thomas Hobbes' Leviathan.
Socialists view freedom as a concrete situation as opposed to a purely abstract ideal. Freedom is a state of being where individuals have agency to pursue their creative interests unhindered by coercive social relationships, specifically those they are forced to engage in as a requisite for survival under a given social system. Freedom thus requires both the material economic conditions that make freedom possible alongside social relationships and institutions conducive to freedom.
The socialist conception of freedom is closely related to the socialist view of creativity and individuality. Influenced by Karl Marx's concept of alienated labor, socialists understand freedom to be the ability for an individual to engage in creative work in the absence of alienation, where "alienated labor" refers to work people are forced to perform and un-alienated work refers to individuals pursuing their own creative interests.
For Karl Marx, meaningful freedom is only attainable in a communist society characterized by superabundance and free access. Such a social arrangement would eliminate the need for alienated labor and enable individuals to pursue their own creative interests, leaving them to develop and maximize their full potentialities. This goes alongside Marx's emphasis on the ability of socialism and communism progressively reducing the average length of the workday to expand the "realm of freedom", or discretionary free time, for each person. Marx's notion of communist society and human freedom is thus radically individualistic.
Some authors have suggested that a virtuous culture must exist as a prerequisite for liberty. Benjamin Franklin stated that "only a virtuous people are capable of freedom. As nations become corrupt and vicious, they have more need of masters." Madison likewise declared: "To suppose that any form of government will secure liberty or happiness without any virtue in the people, is a chimerical idea." John Adams acknowledged: "Our constitution was made only for a moral and religious people. It is wholly inadequate to the government of any other."
Freedom from arbitrary, despotic, or autocratic control; independence, esp. from a foreign power, monarchy, or dictatorship.
This also is remarkable in India, that all Indians are free, and no Indian at all is a slave. In this the Indians agree with the Lacedaemonians. Yet the Lacedaemonians have Helots for slaves, who perform the duties of slaves; but the Indians have no slaves at all, much less is any Indian a slave.
libertarianism, political philosophy that takes individual liberty to be the primary political value
Genuine freedom as Marx described it, would become possible only when life activity was no longer constrained by the requirements of production or by the limitations of material scarcity...Thus, in the socialist view, freedom is not an abstract ideal but a concrete situation that ensues only when certain conditions of interaction between man and nature (material conditions), and man and other men (social relations) are fulfilled.
Socialists consider the pleasures of creation equal, if not superior, to those of acquisition and consumption, hence the importance of work in socialist society. Whereas the capitalist/Calvinist work ethic applauds the moral virtue of hard work, idealistic socialists emphasize the joy. This vision of 'creative man', Homo Faber, has consequences for their view of freedom...Socialist freedom is the freedom to unfold and develop one's potential, especially through unalienated work.
Affluence and increased provision of free goods would reduce alienation in the work process and, in combination with (1), the alienation of man's 'species-life'. Greater leisure would create opportunities for creative and artistic activity outside of work.
Marx believed the reduction of necessary labor time to be, evaluatively speaking, an absolute necessity. He claims that real wealth is the developed productive force of all individuals. It is no longer the labor time but the disposable time that is the measure of wealth.
