Liberty is considered so essential to human life that countless arguments against it are not enough to convince humans to compromise it. The scholar Caudwell noted that “Liberty is a concept about whose nature men have quarrelled perhaps more than about any other”. Individual liberty serves as one of the central pillars of Liberal Political Thought.
Historically, Greek Political Thought refused to accept the notion of individual liberty standing against society and the state. However, in modern times, the principle of liberty places the interests of the individual ahead of society and the state.
While the terms “Liberty” and “Freedom” share almost similar meanings, they are often used separately to delineate ideological differences between Liberal and Socialist Thought. Specifically, “Freedom” denotes a state of being free from oppression, whereas “Liberty” refers to the freedom to act in one’s own way.
Key Definitions of Liberty
Various political philosophers have conceptualized liberty in distinct ways:
- Thomas Hobbes: Defined liberty as the absence of external impediments, which might otherwise limit a person’s power to do what they want.
- John Locke: Famously stated, “Where there is no Law, there is no Freedom”.
- Jean-Jacques Rousseau: Argued that liberty consists in obedience to the General Will.
- Pericles: Believed that freedom meant advancement and political activity for full citizens.
- T. H. Green: Viewed liberty as the positive power of doing and enjoying things that are worthy of being done and enjoyed.
- L. T. Hobhouse: Argued that the unchartered freedom of one person would mean conditional servitude for everyone else; therefore, freedom enjoyed by all requires imposing some restraint upon all.
- Harold J. Laski: Described liberty as the absence of restraints upon social conditions that are necessary guarantees of individual happiness in modern civilization.
- Karl Marx: Defined freedom as the “Recognition of necessity”.
- G. W. F. Hegel: Stated that liberty is obedience to the law.
Ancient vs. Modern Liberty: Benjamin Constant
In his renowned work The Liberty of Ancients Compared with that of Moderns, Benjamin Constant drew a sharp distinction between two historical models of liberty:
- Liberty of the Ancients: This was a participatory, republican form of liberty. It granted citizens the right to directly influence politics through debates and votes within the public assembly.
- Liberty of the Moderns: In contrast, this form of liberty is based on the possession of civil liberties, adherence to the rule of law, and freedom from excessive state interference.
Two Concepts of Liberty: Isaiah Berlin
In a famous 1958 lecture, which was later published in his 1969 book Four Essays on Liberty, Isaiah Berlin categorized the concept of liberty into Positive and Negative Liberty. Berlin granted that both concepts are valid human ideals and are necessary for any free and civilized society.
| Feature | Negative Liberty | Positive Liberty |
| Core Definition | The absence of restraint or interference from the state and society in an individual’s personal affairs. | Understood as “self-mastery” and a positive condition for the free and full development of the individual in society. |
| Role of the State | Considers the state a “necessary evil” and advocates for limited state power. | Considers the state a facilitator and allows positive action by the state to promote human welfare. |
| Underlying Philosophy | Assumes individuals are rational beings who should be free to make their own choices, believing that “that government is the best which governs the least”. | Emphasizes the presence of social and economic conditions, viewing liberty as an opportunity to do something worth doing. |
| Key Proponents | Thomas Hobbes, John Locke, Benjamin Constant, Tocqueville, Thomas Jefferson, Edmund Burke, Adam Smith, Ricardo, Thomas Paine, Bentham, J. S. Mill, Milton Friedman, Robert Nozick, Fredrick Hayek, David Friedman, and Ludwig Von Mises. | Rousseau, Immanuel Kant, T. H. Green, Bosanquet, Barker, Harold J. Laski, C. B. Macpherson, Maynard Keynes, Hobson, L. T. Hobhouse, John Rawls, Ronald Dworkin, and Amartya Sen. |
Prominent Views on Liberty
J. S. Mill’s Harm Principle
In his 1859 book On Liberty, J. S. Mill provided a robust defense of the concept of liberty. He aimed to defend what he referred to as “one very simple principle,” now commonly known as the “Harm Principle”. This principle asserts that the only valid reason mankind is warranted to interfere with the liberty of action of any individual is for self-protection and to prevent harm to others. Mill’s political thought fundamentally represents “Negative Liberty,” but his acknowledgment of the state’s responsibility for the skill and quality development of citizens, including state-sponsored education, shows elements of “Positive Liberty”. As a result, Mill is viewed as a transitional figure belonging to the age of transition from Negative to Positive Liberal Thought.
Positive Liberty: Laski and Macpherson
Harold J. Laski and C. B. Macpherson both expanded on the concept of Positive Liberty, emphasizing the necessary socio-economic conditions for human development.
- Harold J. Laski: He defined liberty as the eager maintenance of an atmosphere where men have the opportunity to be their best selves.
- While Laski viewed “Private Liberty” as mainly a negative thing, he argued that Political and Economic Liberties require specific socio-economic conditions for their fulfillment, making them positive in nature.
- Laski outlined three positive conditions essential for the realization of liberty: the absence of special privileges, the presence of rights, and a responsible government.
- C. B. Macpherson: He defined Positive Liberty as the liberty to act as a full human being.
- Because this form of liberty holds the potential for human development, Macpherson referred to it as “Developmental Liberty”.
- Macpherson argued that true liberty requires the availability of the means of life and labor to each member of society.
- He suggested that the capitalist mode of production needs to be replaced, asserting that a social model of the state is better suited for achieving Developmental or Positive Liberty.
The Atlantic Charter and Four Freedoms
In a 1941 state of the union speech, US President Roosevelt established the principles of the four freedoms. These identical principles were subsequently adopted as the Atlantic Charter (1941), which provided the objectives of the Allied Powers behind World War II. The four freedoms encompass:
- Freedom of Speech.
- Freedom of Worship.
- Freedom from Fear.
- Freedom from Want.
