How Philosophers Define Property: A Historical Perspective

What does it mean to “own” something? It seems like a simple question – but philosophers have spent centuries debating it. Behind every legal system that protects property today lies a long history of competing ideas about what property actually is, where ownership comes from, and who has the right to hold it. For Indian law students studying intellectual property rights, this philosophical foundation is not just academic context – it shapes how courts interpret ownership, how legislation is drafted, and how we understand the relationship between individuals, the state, and society. Here is a look at five thinkers whose definitions of property fundamentally shaped legal thought.

Thomas Hobbes (1588-1679): property as a creation of the sovereign 🔗

Thomas Hobbes approached property with a fundamental question: how can anyone call anything truly theirs? His answer, developed in Leviathan (1651), was stark and unsentimental. According to the Stanford Encyclopedia of Philosophy, Hobbes argued that there is no natural “mine” or “thine” – property only exists when a sovereign authority creates and enforces it.

For Hobbes, life without a governing authority was a “state of nature” – a condition of perpetual conflict where no one’s possessions were secure. The only way to guarantee peace, and therefore ownership, was to submit to a sovereign whose commands everyone agreed to follow. Property rights, in this view, are entirely dependent on that sovereign’s recognition. The state does not protect pre-existing property rights; it creates them.

This has significant legal implications. As legal commentators have noted, under Hobbes’s framework, the sovereign holds ultimate authority over all property, which philosophically justifies taxation, regulation, and even expropriation in the public interest. Individual ownership is real, but it is conditional – it can be limited or revoked by the state that gave it life. This reasoning echoes in modern debates about eminent domain and the state’s power to acquire private land for public use.

James Harrington (1611-1677): property as the foundation of political power 🔗

A contemporary of Hobbes, James Harrington took the opposite view in his landmark work The Commonwealth of Oceana (1656). Where Hobbes saw political power as the source of property rights, Harrington reversed the equation entirely. According to Britannica, Harrington believed that revolution itself is a consequence of the separation of economic and political power.

His central argument was that the distribution of property in a society determines its form of government. In his own words, where one ruler controls all the land, absolute monarchy results; where an aristocracy holds most of it, mixed monarchy follows; but where property is widely distributed among the people, only a republic can provide stable government.

Harrington famously expressed this as: empire follows the balance of property. New World Encyclopedia notes that he proposed political power should be shared among all men of property, with laws limiting individual accumulation of wealth. His ideas anticipated later thinkers – including Marx – in recognizing that economic structures shape political ones. For legal students, Harrington’s framework helps explain why land reform legislation in post-independence India was considered a deeply political act, not merely an economic one.

Sir Robert Filmer (1588-1653): property as divine patriarchal inheritance 🔗

Sir Robert Filmer offered perhaps the most unusual – and historically important – theory of property. In his posthumously published work Patriarcha (1680), Filmer traced all property rights back to God’s original grant of dominion to Adam. From Adam, this dominion passed down through inheritance to kings, who were essentially Adam’s heirs on earth.

As summarized by UCF’s Introduction to Philosophy, Filmer’s position amounted to a defence of the divine right of kings to absolute authority. In this framework, property rights were analogous to household goods that a father may give or take back from his children at will – subjects had no independent right to own property that could override the monarch’s authority.

Filmer’s theory was significant not because it was widely accepted, but because it provoked John Locke into developing the most influential counter-argument in property theory. Locke devoted his entire First Treatise of Government to dismantling Filmer’s patriarchal model before articulating his own labour-based theory. Without Filmer’s provocation, Locke’s property theory might never have taken the form it did.

John Locke (1632-1704): property as a natural right earned through labour 🔗

John Locke’s theory of property, set out in his Second Treatise of Government (1690), remains the most cited and most consequential in the Western legal tradition. The Stanford Encyclopedia of Philosophy describes Locke’s starting point as remarkable: he began by acknowledging that God gave the world to humanity in common, which meant he had to explain how any individual could come to hold private ownership of what was originally shared.

His answer was the labour theory of property. Locke argued that every person owns their own body and, by extension, the work produced by their labour. When a person mixes their labour with an unowned natural resource – clearing land, harvesting crops, crafting an object – they annex something of themselves to it and thereby acquire a property right in it. This was a moral justification for private ownership that required no sovereign’s approval.

Locke also placed two important limitations on this right. First, the sufficiency proviso: one can only appropriate what leaves “enough and as good” for others. Second, the spoilage proviso: one cannot take more than one can use before it spoils. These conditions were designed to prevent unjust accumulation.

Locke’s influence on law is immense. His ideas inspired constitutional protections in the American and French revolutions and the idea that governments must protect rights that exist prior to and independent of the state. In the context of intellectual property – directly relevant to this course – Locke’s labour theory provides the foundational moral argument for why a creator should have exclusive rights over their invention or expression: they mixed their mental labour with an idea to produce something new.

Sir William Blackstone (1723-1780): property as absolute individual dominion 🔗

Sir William Blackstone provided what became the most quoted legal definition of property in the English-speaking world. In his Commentaries on the Laws of England, published between 1765 and 1769, Blackstone described property as that sole and despotic dominion which one man claims and exercises over the external things of the world, in total exclusion of the right of any other individual in the universe.

This definition is striking for its absolutism. Blackstone was not describing how property actually operated in English law – his own Commentaries were filled with exceptions, shared rights, and limitations. Rather, he was articulating an ideal: that the very concept of property rests on the idea of exclusive control. To own something is to be able to exclude all others from it.

The Internet Encyclopedia of Philosophy notes that Blackstone’s “total exclusion” formulation captures what legal theorists call Full Liberal Ownership – the intuitive sense that a property holder has a uniquely privileged relationship with a resource that all others must respect. Britannica describes the Commentaries as the foundation of university legal education in both England and North America, cementing Blackstone’s influence across the common law world.

For Indian law, this influence is direct. India inherited the English common law framework through colonial rule, and the Blackstonian concept of absolute ownership underpinned early Indian property law. The tension between this absolutist conception and the social welfare goals of independent India is precisely what drove the constitutional debates around property rights – eventually leading to the removal of the right to property from the list of fundamental rights under Article 19 and its relocation as a mere legal right under Article 300A of the Constitution.

How these philosophies connect to modern Indian property law 🔗

These five philosophers did not write in isolation. Each was responding to the political crises of their time – civil wars, colonial expansion, struggles between monarchs and parliaments. But their arguments crystallised into legal principles that survive today.

Hobbes’s state-centric view finds expression wherever the government asserts eminent domain or land acquisition powers. Harrington’s insight – that property distribution shapes political structures – is visible in post-independence land reform legislation like the Zamindari Abolition Acts. Filmer’s theory, though discredited, helped sharpen the argument that property rights must have a rational, non-arbitrary basis. Locke’s labour theory is the moral backbone of intellectual property law – the reason why an inventor or an author can claim exclusive rights over their creation. And Blackstone’s formulation of exclusive dominion continues to define how courts understand ownership in property disputes.

Understanding these origins matters because law is not created in a vacuum. When a court interprets what it means to “own” a copyright, or when Parliament debates the limits of land acquisition, the reasoning traces back – however indirectly – to debates that Hobbes, Harrington, Filmer, Locke, and Blackstone were having in 17th- and 18th-century England.

What do you think? Given that Locke’s labour theory is the moral foundation for intellectual property rights, how well does it apply to modern digital creations – where ideas are infinitely reproducible and “labour” is increasingly collaborative? And if Harrington was right that property distribution shapes political power, what does India’s persistent inequality in land ownership say about the health of its democratic institutions?
