Individual contributors to classical liberalism and political liberalism are associated with philosophers of the Enlightenment. Liberalism as a specifically named ideology begins in the late 18th century as a movement towards self-government and away from aristocracy. It included the ideas of self-determination, the primacy of the individual and the nation as opposed to the state and religion as being the fundamental units of law, politics and economy.

Since then liberalism broadened to include a wide range of approaches from Americans Ronald Dworkin, Richard Rorty, John Rawls and Francis Fukuyama as well as the Indian Amartya Sen and the Peruvian Hernando de Soto. Some of these people moved away from liberalism while others espoused other ideologies before turning to liberalism. There are many different views of what constitutes liberalism, and some liberals would feel that some of the people on this list were not true liberals. It is intended to be suggestive rather than exhaustive. Theorists whose ideas were mainly typical for one country should be listed in that country's section of liberalism worldwide. Generally only thinkers are listed whereas politicians are only listed when they also made substantial contributions to liberal theory beside their active political work.
Aristotle

Aristotle (Athens, 384–322 BC) is revered among political theorists for his seminal work Politics. He made invaluable contributions to liberal theory through his observations on different forms of government and the nature of man.
He begins with the idea that the best government provides an active and "happy" life for its people. Aristotle then considers six forms of government: Monarchy, Aristocracy, and Polity on one side as 'good' forms of government, and Tyranny, Oligarchy, and Democracy as 'bad' forms. Considering each in turn, Aristotle rejects Monarchy as infantilizing of citizens, Oligarchy as too profit-motivated, Tyranny as against the will of the people, Democracy as serving only to the poor, and Aristocracy (known today as Meritocracy) as ideal but ultimately impossible. Aristotle finally concludes that a polity—a combination between democracy and oligarchy, where most can vote but must choose among the rich and virtuous for governors—is the best compromise between idealism and realism.
In addition, Aristotle was a firm supporter of private property. He refuted Plato's argument for a collectivist society in which family and property are held in common: Aristotle makes the argument that when one's own son or land is rightfully one's own, one puts much more effort into cultivating that item, to the ultimate betterment of society. He references barbarian tribes of his time in which property was held in common, and the laziest of the bunch would always take away large amounts of food grown by the most diligent.
Cicero
His Stoic, Cato, advocated for Greek Stoicism in Cicero's books. It's a development of Aristotle's ethics and goes further, advocating equal rights for all people. It was found to be scientifically true on inspection in the '90s, by Becker (1998).[1] He was also a major influence to John Locke.
Laozi
Laozi was a Chinese philosopher and writer, considered the founder of Taoism. Arguing that Laozi is a libertarian, James A. Dorn wrote that Laozi, like many 18th-century liberals, "argued that minimizing the role of government and letting individuals develop spontaneously would best achieve social and economic harmony."[2]
The Islamic Golden Age (8th to 14th century) was marked by a flourishing of intellectual activity in the Islamic world. Several scholars and thinkers from this era contributed to ideas that align with certain liberal principles, emphasizing reason, justice, and individual rights.
Al-Farabi (872–950)
Al-Farabi, known as "the Second Teacher," was a philosopher influential in transmitting Greek philosophy to the Islamic world. His political philosophy, seen in works like The Virtuous City,[3] stressed the importance of justice and the common good in governance, influencing both Muslim and European thought.[4]
Averroes (1126–1198)
Ibn Rushd, a Spanish-Arab philosopher, advocated for the compatibility of reason and philosophy with Islamic faith. His commentaries on Aristotle and independent works promoted the separation of reason and revelation, profoundly influencing both Islamic and Western thought.[5]
Avicenna (980–1037)
Ibn Sina, a polymath known for contributions to medicine and metaphysics, delved into political philosophy. In *The Book of Healing*, he discussed the need for a well-ordered state, emphasizing the role of a philosopher-king guided by reason and wisdom.[6]
Ibn Tufayl (1105–1185)
Ibn Tufail, a philosopher and physician, explored individualism and reason in Hayy ibn Yaqdhan.[7] The novel discussed a person raised in isolation, emphasizing themes of individual pursuit of knowledge.
Niccolò Machiavelli
 | This section's factual accuracy is disputed. (June 2024) |
Niccolò Machiavelli (Florence, 1469–1527), best known for his Il Principe was the founder of realist political philosophy, advocated republican government, citizen armies, protection of personal property, and restraint of government expenditure as being necessary to the liberties of a republic. He wrote extensively on the need for individual initiative—virtu—as an essential characteristic of stable government. He argued that liberty was the central good which government should protect, and that "good people" would make good laws, whereas people who had lost their virtue could maintain their liberties only with difficulty. His Discourses on Livy outlined realism as the central idea of political study and favored "Republics" over "Principalities".
Machiavelli differed from true liberal thinking however, in that he still noted the benefits of princely governance.[8] He states that republican leaders need to "act alone" if they want to reform a republic, and offers the example of Romulus, who killed his brother and co-ruler to found a great city.[9] Republics need to refer to arbitrary and violent measures if it is necessary to maintain the structure of the government, as Machiavelli says that they have to ignore thoughts of justice and fairness.[10]
Anti-statist liberals consider Machiavelli's distrust as his main message, noting his call for a strong state under a strong leader, who should use any means to establish his position, whereas liberalism is an ideology of individual freedom and voluntary choices.

.jpg)
Thomas Hobbes (England, 1588–1679) theorized that government is the result of individual actions and human traits, and that it was motivated primarily by "interest", a term which would become crucial in the development of a liberal theory of government and political economy, since it is the foundation of the idea that individuals can be self-governing and self-regulating. His work Leviathan, did not advocate this viewpoint, but instead that only a strong government could restrain unchecked interest: it did, however, advance a proto-liberal position in arguing for an inalienable "right of nature," the right to defend oneself, even against the state.[citation needed] Though his own ideological position is open to debate, his work influenced Spinoza, Locke, Hamilton, Jefferson, Madison and many other liberals.[12]

Spinoza
Baruch Spinoza (Netherlands, 1632–1677) in his Tractatus Theologico-Politicus (TTP) (1670) and Tractatus Politicus (1678) defends the importance of separation of church and state as well as forms of democracy. In the TTP, Spinoza articulates a strong critique of religious intolerance and a defense of secular government against the power of religious authorities.[13][14] Spinoza laid the philosophical groundwork for the emancipation of Jews, putting them on an equal footing as other citizens.[15]

John Locke
John Locke's (England, 1632–1704) notion that a "government with the consent of the governed" and man's natural rights—life, liberty, and estate (property) as well on tolerance, as laid down in A letter concerning toleration and Two treatises of government—had an enormous influence on the development of liberalism. Locke developed a theory of property resting on the actions of individuals, rather than on descent or nobility.

Charles de Montesquieu
Charles de Montesquieu (France, 1689–1755) In The Spirit of Law, Montesquieu expounded the separation of powers in government and society. In government, Montesquieu encouraged division into the now standard legislative, judicial and executive branches; in society, he perceived a natural organization into king, the people and the aristocracy, with the latter playing a mediating role. "I do not write to censor that which is established in any country whatsoever," Montesquieu disclaimed in the Laws; however, he did pay special attention to what he felt was the positive example of the constitutional system in England, which in spite of its evolution toward a fusion of powers, had moderated the power of the monarch, and divided Parliament along class lines.
Montesquieu's work had a seminal impact on the American and French revolutionaries. Ironically, the least liberal element of his thought—his privileging of the aristocracy—was belied by both revolutions. Montesquieu's system came to fruition in America, a country with no aristocracy; in France, political maneuvering by the aristocracy led to the convocation of the 1789 Estates-General and popular revolt.

Adam Smith
Adam Smith (Great Britain, 1723–1790), often considered the founder of modern economics, was a key figure in formulating and advancing economic doctrine of free trade and competition. In his Wealth of Nations Adam Smith outlined the key idea that if the economy is basically left to its own devices, limited and finite resources will be put to ultimately their most efficient use through people acting purely in their self-interest. This concept has been quoted out of context by later economists as the invisible hand of the market.
Smith also advanced property rights and personal civil liberties, including stopping slavery, which today partly form the basic liberal ideology. He was also opposed to stock-holding companies, what today is called a "corporation", because he predicated the self-policing of the free market upon the free association of moral individuals.

In 1831, Tahtawi was part of the statewide effort to modernize the Egyptian infrastructure and education.[33] Three of his published volumes were works of political and moral philosophy. They introduced his Egyptian audience to Enlightenment ideas such as secular authority and political rights and liberty; his ideas regarding how a modern civilized society ought to be and what constituted by extension a civilized or "good Egyptian"; and his ideas on public interest and public good.[34] Tahtawi's work was the first effort in what became an Egyptian renaissance (nahda) that flourished in the years between 1860 and 1940.[35]

John Stuart Mill
John Stuart Mill (United Kingdom, 1806–1873) is one of the first champions of modern "liberalism." As such, his work on political economy and logic helped lay the foundation for advancements in empirical science and public policy based on verifiable improvements. Strongly influenced by Bentham's utilitarianism, he disagrees with Kant's intuitive notion of right and formulates the "highest normative principle" of morals as: Actions are right in proportion as they tend to promote happiness; wrong as they tend to produce the reverse of happiness.
Some consider Mill as the founder of Social liberalism. Although Mill was mainly for free markets, he accepted interventions in the economy, such as a tax on alcohol, if there were sufficient utilitarian grounds. Mill was also a champion of women's rights.

Herbert Spencer
Herbert Spencer (United Kingdom, 1820–1903), philosopher, psychologist, and sociologist, advanced what he called the "Law of equal liberty" and argued against liberal theory promoting more activist government, which he dubbed "a new form of Toryism." He supported a state limited in its duties to the defense of persons and their property. For Spencer, voluntary cooperation was the hallmark of the most vibrant form of society, accommodating the widest diversity of members and the greatest diversity of goals. Spencer's evolutionary approach has been characterized as an extension of Adam Smith's "invisible hand" explanation of economic order; his extensive work on sympathy (in psychology as well as the foundation of ethics, particularly in The Data of Ethics) explicitly carried on Smith's approach in The Theory of Moral Sentiments. Spencer is frequently characterized as a leading Social Darwinist.

İbrahim Şinasi
İbrahim Şinasi (Ottoman Empire, 1826–1871), author, journalist, translator, and newspaper editor. He was the innovator of several fields: he wrote one of the earliest examples of an Ottoman play, he encouraged the trend of translating poetry from French into Turkish, he simplified the script used for writing the Ottoman Turkish language, and he was one of the first of the Ottoman writers to write specifically for the broader public. Şinasi used his newspapers, Tercüman-ı Ahvâl and Tasvîr-i Efkâr, to promote the proliferation of European Enlightenment ideals during the Tanzimat period,[40] and he made the education of the literate Ottoman public his personal vocation. Though many of Şinasi's projects were incomplete at the time of his death, "he was at the forefront of a number of fields and put his stamp on the development of each field so long as it contained unsolved problems." Şinasi, influenced by Enlightenment thought, saw freedom of expression as a fundamental right and used journalism in order to engage, communicate with, and educate the public. By speaking directly to the public about government affairs, Şinasi declared that state actions were not solely the interest of the government.[41]

Isaiah Berlin
Isaiah Berlin (Latvia/United Kingdom, 1909–1997) is most famous for his attempt to distinguish 'two conceptions of liberty'. Berlin argued that what he called 'positive' and 'negative' liberty were mutually opposing concepts. Positive conceptions assumed that liberty could only be achieved when collective power (in the form of church or state) acted to 'liberate' mankind from its worst aspects. These, Berlin felt, tended towards totalitarianism. Negative conceptions, by contrast, argued that liberty was achieved when individuals were given maximal freedom from external constraints (so long as these did not infringe on the freedom of others to achieve the same condition). Berlin was also a critic of dogmatic Enlightenment rationalism on the grounds that it was unable to accommodate value pluralism.

Michael Meadowcroft
A biography described the British politician Michael Meadowcroft as "the main, indeed very nearly the only, philosopher of applied Liberalism within the old Liberal Party from the late 1960s onwards".[54] On the merger of the Liberal Party and the Social Democratic Party in the UK to form the Liberal Democrats, Meadowcroft initially reconstituted a new Liberal Party with others who did not want to compromise the philosophy of liberalism.[54] However, the new Liberal Party became increasingly Eurosceptic under the leadership of Steve Radford and Meadowcroft joined the Liberal Democrats in 2007.[55] He has regularly argued for the importance of political philosophy and that members of the Liberal Democrats require more conviction in their beliefs.[56][57][58]

In his book Multicultural Citizenship. A Liberal Theory of Minority Rights he argues that certain "group-differentiated rights" of minority cultures can be consistent with these liberal-democratic principles.
