Picture a world with no police, no courts, no government of any kind. What would people do? Many thinkers assumed the answer was chaos and violence. John Locke disagreed. Writing in his Second Treatise of Government (1689), he argued that even without a single ruler or law court, human beings would mostly live in peace, guided by reason and a moral law that binds everyone. This idea-the “state of nature” as a condition of peace rather than war-became one of the most influential concepts in modern political thought. It shaped the way we think about rights, government, and the very purpose of the state.

What is the state of nature?
The state of nature is a hypothetical condition: it describes what human life would be like before any government or political authority existed. Locke used it as a starting point. To understand why we have governments and what powers they should have, he reasoned, we first need to understand what people are like without one.
For Locke, the state of nature is defined by two key features: perfect freedom and equality. People are free to act and to use their possessions as they see fit, without asking permission from anyone else. They are also equal, because no person is naturally placed above another. As Locke put it, all individuals are “creatures of the same species and rank” who share the same faculties, so there is no natural reason for one to rule over the others.
This is very different from imagining a lawless free-for-all. Freedom in the state of nature does not mean people can do absolutely anything they want. Locke described the state of nature as a condition without government but not without mutual obligation. There is still a rule governing everyone, and that rule comes from natural law.
Natural law and the role of reason
At the heart of Locke’s state of nature is the law of nature. This is a moral law that applies to all human beings everywhere, whether or not any government has written it down. It exists before and independently of any human-made law.
What does this law require? In one of the most quoted passages of the Second Treatise, Locke wrote that the law of nature teaches all mankind that, being equal and independent, no one ought to harm another in his life, health, liberty, or possessions. In short, everyone has a duty not to damage the basic rights of others. These rights-to life, liberty, and property-form the foundation of Locke’s entire political theory.
Where does this law come from?
Locke offered two interlocking sources for the law of nature. The first is God. Locke argued that humans are the workmanship of one wise maker, sent into the world to do his business. Because we are God’s creation, we have a duty to preserve ourselves and, where possible, to preserve others too. We do not have the right to destroy one another, just as we would not expect a craftsman’s tools to destroy each other.
The second source is reason. Locke held that the law of nature is accessible to anyone who simply uses their rational mind. You do not need a holy book or a king’s decree to discover it-you only need to think clearly about your situation and the equal standing of others. Reason, for Locke, is the law of nature in practice. This is a deeply optimistic view of human nature: it assumes most people, most of the time, can work out the right thing to do and are capable of cooperation.
Everyone is the enforcer
Here is a clever problem Locke had to solve. A law is useless if no one can enforce it. But in the state of nature there are no police and no judges. So who punishes wrongdoers?
Locke’s answer is striking: everyone does. Because all people are equal and there is no higher authority, each individual holds what Locke called the “executive power of the law of nature.” This means any person has the right to punish someone who violates natural law. As Locke explained, if the law of nature had no one to enforce it, it would be in vain, with no one able to restrain offenders or protect the innocent. Crucially, this punishment is not about revenge or cruelty. It must be measured by what Locke called “calm reason,” limited to what is proportionate-enough for reparation and to restrain future harm, and no more.
A state of peace, not a state of war
The most important thing to understand about Locke’s idea is the sharp line he draws between the state of nature and the state of war. These are two different conditions, and confusing them was, in Locke’s view, a mistake made by earlier thinkers.
The state of nature, properly understood, is a condition of peace, goodwill, mutual assistance, and preservation. People living under reason and natural law generally respect each other’s rights and can even help one another. They can work, trade, raise families, and form communities long before any formal government appears.
The state of war is different. It begins when someone abandons reason and uses force, or the threat of force, against another person without right-attacking their life, liberty, or property. When that happens, the natural-law relationship breaks down and a conflict opens up. This state of war, Locke argued, continues until the aggressor is stopped and justice is restored, either through compensation or punishment. Importantly, a violation does not turn the whole world into a battlefield, as the peace among everyone else remains intact. War is the exception, triggered by specific wrongs, not the normal condition of human life.
The contrast with Hobbes
To appreciate how distinctive Locke’s view is, it helps to compare it with Thomas Hobbes, who wrote a few decades earlier. In his work Leviathan (1651), Hobbes painted the state of nature as a grim “war of all against all,” a condition in which life was famously “nasty, brutish and short.” For Hobbes, the state of nature simply was a state of war, because he saw human beings as fundamentally selfish and quarrelsome.
Locke split apart what Hobbes had fused together. For Locke, the state of nature and the state of war are two separate conditions: the former a state of peace and cooperation, the latter a state of enmity and destruction that arises only when natural law is broken. This difference flows from their opposing views of human nature. Hobbes believed people were driven mainly by fear and self-interest, while Locke believed people were rational enough to recognise and respect the rights of others.
This disagreement led to very different conclusions about government. Because Hobbes saw the natural condition as so dangerous, he argued people should hand over nearly all their rights to an absolute ruler-a powerful sovereign who keeps order at almost any cost. Locke, viewing the natural condition as basically tolerable, argued for something far more limited. People give up only the right to interpret and enforce natural law themselves; they keep their fundamental rights, and government exists to serve them, not to dominate them.
Property in the state of nature
One of Locke’s most original arguments is that private property exists even before government does. This matters because it means government does not create property rights-it simply protects rights that already exist.
How does property arise? Locke’s answer is the famous labour theory of property. He begins with the idea that every person owns themselves: the labour of your body and the work of your hands belong to you. When you take something from nature and mix your labour with it-gathering acorns from the ground, picking apples, or cultivating land-you join something of your own to it and thereby make it your property. The acorns a man gathers become his, Locke argued, the moment he picks them up and expends effort.
This right is not unlimited. Locke attached conditions, the best known being that one should leave “enough, and as good” for others-a principle later writers call the Lockean proviso. The point is that productive, peaceful economic life is possible in the state of nature. People can own things, work, and prosper without a state telling them what belongs to whom.
If the state of nature is so peaceful, why leave it?
This raises an obvious question. If people can live peacefully, enjoy rights, and own property without any government, why would they ever bother to create one?
Locke’s answer is honest: the state of nature, though peaceful, has serious inconveniences. The problem is not that people are wicked, but that the system of enforcement is unreliable. Three difficulties stand out.
No settled law: The law of nature exists, but it is unwritten, and people interpret it differently. Honest individuals can genuinely disagree about what justice requires in a particular dispute.
No impartial judge: Since everyone enforces natural law themselves, people end up acting as judges in their own cases. Locke admitted this was a serious inconvenience and a primary reason for leaving the state of nature. People tend to be biased in their own favour and can react with too much heat when they feel wronged.
No reliable enforcement: Even when someone is clearly in the right, they may lack the power to actually punish a wrongdoer or recover what they have lost, especially against a stronger opponent.
These inconveniences make rights insecure. A peaceful disagreement over property, for example, can escalate into a state of war when there is no neutral authority to settle it. So people consent to leave the state of nature and form a political society. They agree to give up only their individual power to interpret and enforce natural law, handing it to a common government whose job is to protect their life, liberty, and property more securely than they could alone. Government, in this view, is a tool created by free and equal people for their own benefit-and one whose powers remain limited by the very natural law it was created to uphold.
Why Locke’s idea still matters
Locke’s state of nature is more than a historical curiosity. The claim that people have rights to life, liberty, and property before and independent of any government has had enormous consequences. It implies that the purpose of the state is to protect pre-existing rights, not to grant them, and that a government which systematically violates those rights loses its legitimacy. These ideas fed directly into the language of modern constitutions, declarations of rights, and the broader liberal tradition that still shapes democratic societies today. The notion that legitimate authority rests on the consent of free and equal individuals remains a cornerstone of how we evaluate governments.
What do you think? If the state of nature were really as peaceful as Locke describes, do the “inconveniences” he lists truly justify creating a government-or could free people find other ways to settle their disputes? And do you find Locke’s optimistic view of human reason more convincing than Hobbes’s darker picture, or does the truth lie somewhere in between?
