Introduction to Liberalism

  • Liberalism emerged in the 17th and 18th centuries as thinkers began challenging absolute monarchy, religious authority and rigid social hierarchies

    • Early liberals such as John Locke argued that individuals possess natural rights and that government should only exist with the consent of the governed

  • Over time, liberalism has centred on protecting individual freedom and limiting state power

  • Although classical and modern liberals disagree on how far the state should intervene, all liberals share a commitment to core principles about the individual, society and government

Key principles of Liberalism

Liberal principles include individualism, rationalism and equality

Core principle: individualism

Core idea

  • Liberals believe individuals have inherent worth

    • They therefore possess rights that should be respected and protected

  • Individuals are seen as rational beings

    • They are capable of making their own decisions and taking responsibility for their actions

  • Liberalism supports freedom of conscience

    • Each person should be free to follow their own beliefs without unnecessary state interference

Key thinkers

  • John Locke

    • Individuals have natural rights of  life, liberty, and property ownership

    • These existed before the formation of a government

  • Mary Wollstonecraft

    • Women’s rationality means they deserved education to develop their individual potential

Different strands of individualism

Egoistical individualism

Developmental individualism

  • Individuals naturally act in their own interest and should be left free from heavy state control

  • Individuals can grow and flourish with support from the state (e.g. education, welfare)

  • Tolerance is essential to individualism

    • If individuals want their freedoms protected, they must also allow others to live according to their own beliefs

Do Liberals agree on this principle?

Two speech bubbles: Left discusses agreement that individual autonomy is crucial; right notes classical liberals prefer minimal interference, modern support state help.

Core principle: freedom and liberty

Core idea

  • Freedom is essential to liberalism

  • Individuals should be free to make their own decisions as long as they do not harm others

Key thinkers

  • John Stuart Mill

    • The Harm Principle - defends individual freedom unless behaviour harms others

  • John Rawls

    • Argued for basic liberties and equality of opportunity to allow individuals to flourish

Negative vs positive liberty

Negative liberty

Positive liberty

  • Freedom from interference by the state

  • Favoured by classical liberals

  • Freedom to achieve one’s goals, sometimes requiring state support

  • Favoured by modern liberals

Do Liberals agree on this principle?

Two speech bubbles: one discusses agreement within liberalism on freedom and personal autonomy; the other highlights differences on negative versus positive liberty.

Core principle: the state

Core idea

  • Liberals support a limited government with checks and balances to prevent tyranny

    • The main purpose of the state is to protect individual rights

    • The state exists only due to the consent of the governed, expressed through democratic participation

  • The state is viewed as a necessary evil

    • It is necessary to protect rights but potentially dangerous if it becomes too powerful

Key thinkers

  • John Locke

    • Argued for the social contract

      • Governments only have authority because citizens consent in return for rights protection

  • John Rawls

    • Supported state involvement to prevent individuals succeeding at the expense of others

Do Liberals agree on this principle?

Two speech bubbles: one explaining liberal agreement on state role to protect rights, the other showing conflict between classical and modern liberal state views.

Core principle: rationalism

Core idea

  • Liberals believe humans are rational, capable of reasoning and making informed decisions

    • Rationalism supports freedom

      • Because individuals can think for themselves, they should be allowed to choose their own path

    • Rational discussion and debate can lead to peaceful reform, rather than relying on tradition or authority

Key thinkers

  • John Locke

    • Challenged traditional authority such as the monarchy

  • Mary Wollstonecraft

    • Argued that women are rational and should have equal rights

Do Liberals agree on this principle?

Two speech bubbles: one highlights agreement in liberalism on human rationality justifying freedom; the other shows differences in classical and modern views.

Core principle: equality and social justice

Core idea

  • Liberals support formal equality, meaning all individuals have the same legal rights

  • They also believe in equality of opportunity, allowing individuals the chance to develop their abilities and talents

Key thinkers

  • John Rawls

    • The ‘theory of justice’ argued for state-led redistribution to improve opportunities for the least advantaged

  • Betty Friedan

    • Argued for personal and professional gender equality, supported by formal equality but also changing societal attitudes towards women

Types of equality

Foundational equality

Formal equality

  • Everyone is born equal in rights

  • Laws must protect everyone equally

Equality of opportunity

Social justice

  • Barriers to progress should be minimised so individuals can flourish

  • The state should remove barriers that prevent individuals reaching their potential

Do Liberals agree on this principle?

Two speech bubbles outline agreements and disagreements within liberalism, focusing on equality under the law and the state's role in social justice.

Core principle: liberal democracy

  • Liberal democracy combines democratic participation with liberal values such as rights, tolerance and the rule of law

    • Features include free and fair elections, government accountability, constitutionalism, protected rights and political tolerance

  • Liberal democracy protects freedom and ensures government power is limited

    • However, democracy can risk tyranny of the majority, where popular opinion undermines individual rights

  • All liberals agree democracy is necessary to secure liberty and rights

    • Classical liberals emphasise meritocratic democracy

    • Modern liberals emphasise democratic systems that promote equality of opportunity

Key thinkers

  • John Locke

    • Argued for the social contract and government by consent

  • Mary Wollstonecraft

    • Argued for women’s equal rights so they could participate fully in politics

Do Liberals agree on this principle?

Two speech bubbles contrast liberalism: agreement on democracy for liberty and rights, and disagreement on meritocratic versus equal opportunity systems.
