What this dot point is asking
QCAA wants Year 11 students to define liberalism, to trace its development from 17th century origins through the 19th-century laissez-faire phase to 20th-century social liberalism, and to identify its impact on the governance of modern democracies.
Defining liberalism
Liberalism is the political idea that the individual is the basic unit of political life, that individual liberty is the primary political good, and that legitimate government rests on the consent of the governed and operates under the rule of law. Within this broad commitment lie sharp internal disagreements (about the role of the state in the economy, about how positive social conditions of liberty should be guaranteed).
Origins (17th century)
John Locke (1632-1704). Two Treatises of Government (1689). Natural rights to life, liberty and property; government by consent; right of revolution. Foundational text of the liberal tradition.
The Glorious Revolution (1688-1689). Bill of Rights, parliamentary sovereignty, constitutional limits on the monarch. Lived constitutionalism.
Classical liberalism (19th century)
The dominant 19th-century form. Combined:
- Constitutionalism. Limited, representative government under law.
- Civil liberties. Free speech, free assembly, religious toleration, due process.
- Free trade. Repeal of the Corn Laws (1846) under Peel and the Anti-Corn Law League (Cobden, Bright).
- Laissez-faire economics. Adam Smith (Wealth of Nations, 1776), David Ricardo. The night-watchman state.
- Gradual extension of the franchise. British Reform Acts of 1832, 1867, 1884.
Key thinkers: Adam Smith (Scottish economist, free markets), Jeremy Bentham (utilitarian reform), John Stuart Mill (On Liberty, 1859: the harm principle and toleration; The Subjection of Women, 1869: liberal feminism).
Social liberalism (late 19th to mid 20th century)
Classical liberalism's confidence in laissez-faire was challenged by the social conditions of industrial Britain (sanitation, child labour, urban poverty). T.H. Green (1836-1882) and L.T. Hobhouse (Liberalism, 1911) developed positive liberty (the capacity to act, not just freedom from restraint).
Political expression: the British Liberal welfare reforms (1906-1914 under Asquith and Lloyd George) introduced free school meals (1906), old-age pensions (1908), national insurance for sickness and unemployment (1911). In the United States, the New Deal (1933-1939) marked the same shift.
Mid-20th century synthesis
Sir William Beveridge (Social Insurance and Allied Services, 1942). The Beveridge Report proposed cradle-to-grave social insurance and the postwar welfare state.
Isaiah Berlin (Two Concepts of Liberty, 1958). Distinguished negative liberty (freedom from interference) and positive liberty (freedom to flourish), warning that positive liberty taken to extremes could justify coercion in the name of "true" freedom.
Late-20th-century revival of classical liberalism (neoliberalism)
Friedrich Hayek (The Road to Serfdom, 1944). State economic planning leads to tyranny.
Milton Friedman (Capitalism and Freedom, 1962). Returned to free-market liberalism.
Political expression: Thatcher in Britain (1979-1990), Reagan in the United States (1981-1989), Hawke and Keating in Australia (1983-1996). Privatisation, financial deregulation, tax reform.
Impact
- Constitutionalism is now the global default. Most modern states claim a written constitution and an independent judiciary, even when they fail to live up to them.
- Civil liberties are entrenched. Freedom of speech and assembly are written into modern constitutions and into the Universal Declaration of Human Rights (1948).
- The welfare state is liberalism's institutional legacy. Universal health care, pensions, public education trace to social liberal reforms.
- Liberalism remains contested. Internal disputes (classical vs social) and external challenges (from conservatism, socialism, populism) define modern political debate.
In one sentence
Liberalism is the political idea that individual liberty is the highest political good, government rests on consent, and the rule of law constrains power; from Locke's 17th-century natural rights through 19th-century classical liberalism (Smith, Mill, free markets) to 20th-century social liberalism (Beveridge, the welfare state) and the neoliberal revival (Hayek, Friedman), it has shaped almost every form of modern democratic governance.

A Year 11 response.
Thesis. Liberalism evolved from the classical liberalism of the 19th century (limited state, free markets, individual rights) to the social liberalism of the 20th century (welfare provision, market regulation, expanded citizenship rights) in response to industrial inequality, depression, and the experience of the world wars.
Body 1: Classical liberalism. 19th-century liberalism championed laissez-faire economics (Adam Smith, David Ricardo), free trade (the Anti-Corn Law League, 1846), limited government, and constitutional reform. Gladstone's British Liberal Party (1868-1894) embodied this tradition.
Body 2: The challenge of industrial inequality. Late-19th-century industrial conditions raised questions about whether the formally free worker was substantively free. T.H. Green and L.T. Hobhouse argued (1880s-1900s) that liberty requires positive conditions (education, health, employment), not just the absence of legal restraint. The British Liberal welfare reforms (1906-1914) introduced old-age pensions and unemployment insurance.
Body 3: 20th-century social liberalism. The Great Depression and the New Deal (Roosevelt, 1933-1939) entrenched state economic intervention. Beveridge's 1942 report in Britain proposed cradle-to-grave welfare. Isaiah Berlin's "Two Concepts of Liberty" (1958) gave philosophical voice to the distinction between negative and positive liberty.
Conclusion. Liberalism changed because the social conditions liberalism's classical proponents assumed (rough economic equality, a self-regulating market, a small state) ceased to hold. Modern liberalism preserves the commitment to individual liberty but pursues it through different institutional means.
