This is not because he thought that people needed or deserved freedom. He simply thought our meddling was counter-productive. Whenever we intervene in the order of things, we create unintended side effects. We mess things up. Taoists often say, "Things do not get confused; we get confused."

 government, citizen armies, division of power, 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".

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.

Thomas Hobbes

Thomas Hobbes
Thomas Hobbes
Thomas Hobbes of Malmesbury , in some older texts Thomas Hobbs of Malmsbury, was an English philosopher, best known today for his work on political philosophy...

(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. Though it is problematic to classify Hobbes himself as a liberal, his work influenced Locke, Hamilton, Jefferson, Madison and many other later liberals, leading Strauss

. For him, even human behaviour is fully determined, freedom being our capacity to know we are determined and to understand why we act as we do.

Charles de Montesquieu
Charles de Secondat, baron de Montesquieu
Charles-Louis de Secondat, baron de La Brède et de Montesquieu , generally referred to as simply Montesquieu, was a French social commentator and political thinker who lived during the Enlightenment...

(France, 1689–1755)

In The Spirit of the Laws, 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.

He was also a member of the Swedish four-estates parliament, elected three times as representative of the clergy in the northern and western parts of Finland. In his first parliamentary session, 1765–66, he was very successful as a member of the subcommittee that wrote Swedens famous Constitutional Law of the Freedom of Printing, Tryckfrihetsförordningen, of 1766. In this law Chydenius combined freedom of the press, and abolishment of the political censorship

, with free access for the citizens to most government documents. Chydenius liberal system, where transparency reinforces press freedom, and the right for everyone to print the public document reinforces transparency, has been a fundamental constitutional principle in Sweden ever since, except for the years of royal autocracy 1772-1809.

It is now the foundation of the present Tryckfrihetsförordningen of 1949, which is one of the fundamental laws of Sweden.

(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 impinge 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.
