Liberalism: Core Ideas & Principles (Edexcel A Level Politics): Revision Note
Exam code: 9PL0
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

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

Tolerance is essential to individualism
If individuals want their freedoms protected, they must also allow others to live according to their own beliefs

The state is viewed as a necessary evil
It is necessary to protect rights but potentially dangerous if it becomes too powerful

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

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
