What this dot point is asking

Edexcel wants you to explain the core ideas and principles of liberalism (individualism, freedom/liberty, the state, rationalism, equality and social justice, and liberal democracy) and how they apply to human nature, the state, society and the economy, the tension between classical and modern liberalism, and the ideas of the required thinkers. The Section B essay is worth 24 marks and you must apply the thinkers.

Core ideas and principles

The required core ideas:

  • Individualism. The individual is prior to any group; liberals distinguish egoistical individualism (self-interested) from developmental individualism (the flourishing of each person's potential).
  • Freedom/liberty. The supreme value, but exercised under the law so that one person's freedom does not harm others; liberals divide over negative and positive freedom.
  • The state. Necessary to prevent the disorder of a state of nature but a potential threat to liberty, so it must be limited, constitutional and based on consent (a social contract).
  • Rationalism. Humans can reason, define their own interests and improve society, supporting tolerance and progress.
  • Equality and social justice. Foundational equality (all are born equal in worth and rights) and formal equality (equality before the law), leading to equality of opportunity (a meritocracy), but not necessarily equality of outcome.
  • Liberal democracy. A democracy that balances majority rule with limited government and respect for civil liberties, which liberals support but also fear (the tyranny of the majority).

The tension: classical and modern liberalism

The two strands agree on the value of the individual, liberty, reason, tolerance and a limited, constitutional, consensual state, but disagree sharply on what freedom requires and therefore on the size of the state and the role of the economy.

The required thinkers

Apply these in the Section B essay; focus on key ideas.

  • John Locke (1632 to 1704). Social contract and natural rights: legitimate government rests on the consent of the governed and exists to protect life, liberty and property; this justifies limited government. The foundation of classical liberalism.
  • Mary Wollstonecraft (1759 to 1797). Women are rational beings entitled to the same freedom, education and formal equality as men; reason is not gendered. An early liberal feminist argument.
  • John Stuart Mill (1806 to 1873). The harm principle (the only justification for restricting liberty is to prevent harm to others) and the value of individuality and free debate; a bridge between classical and modern liberalism (developmental individualism).
  • John Rawls (1921 to 2002). Justice as fairness: behind a "veil of ignorance" rational people would choose a society with equal liberty and inequalities permitted only if they benefit the worst off, justifying the modern liberal enabling state.
  • Betty Friedan (1921 to 2006). Women are held back by social conditioning and lack of opportunity; equality of opportunity and legal reform can free them, a modern liberal feminist position.

Examples in context

  • Locke's defence of government by consent, the basis of the classical liberal limited state.
  • Mill's harm principle, the enduring liberal test for when liberty may be restricted.
  • Rawls's veil of ignorance, the modern liberal justification for redistribution and the enabling state.
  • The post-war welfare state, a practical expression of modern liberal positive freedom (Beveridge was a Liberal).

Show worked answer →

A Section B 24-mark Core Ideas essay (shown as 20), marked on AO1, AO2 and AO3, that must apply thinkers. Organise by agreement and disagreement, not thinker by thinker.

Agreement: all liberals prize individual freedom and see it as central, "under the law" rather than licence (Locke, Mill).

Disagreement: classical liberals defend negative freedom (freedom from interference; Mill's harm principle), while modern liberals defend positive freedom (the enabling state removing obstacles such as poverty and ignorance; Rawls, Friedan), so they disagree on what freedom requires of the state.

A Level 5 answer weighs the shared commitment to liberty against the deep split over negative and positive freedom, applies named thinkers accurately, and judges, for example, that liberals agree on the value of freedom but disagree fundamentally on how to secure it.

A Section B 24-mark essay (shown as 20) on AO1, AO2 and AO3 that must use thinkers. Plan around the state.

Disagree: classical liberals want a minimal "night-watchman" state that protects natural rights and leaves laissez-faire economics alone (Locke's limited government, Mill); modern liberals want an enabling state providing welfare, education and intervention to deliver positive freedom and equality of opportunity (Rawls, Friedan).

Agree: both reject an arbitrary or unlimited state, insist on government by consent and the rule of law, and support a constitutional, limited state rather than an authoritarian one.

A Level 5 answer judges that classical and modern liberals disagree sharply on the size of the state but agree on its limited, consensual and constitutional nature, applying thinkers throughout.
