The state of nature is a thought experiment used by political philosophers to imagine what human life would look like without government, laws, or organized society. It’s not meant to describe a real historical period. Instead, it’s a tool for answering a fundamental question: why do we need government at all, and what kind of government is justified? The concept was central to 17th and 18th century political philosophy, and the three thinkers most associated with it, Thomas Hobbes, John Locke, and Jean-Jacques Rousseau, reached strikingly different conclusions about what life without authority would actually be like.
Hobbes: Life Without Government Is War
Thomas Hobbes presented the bleakest version of the state of nature in his 1651 work Leviathan. For Hobbes, removing government doesn’t reveal peaceful humans getting along. It reveals a “war of every man against every man,” where life is famously “solitary, poor, nasty, brutish, and short.” His reasoning rests on three basic claims about human behavior. First, people will compete violently to secure basic necessities and material goods. Second, even those who don’t want to fight will do so out of fear for their own safety. Third, people will seek reputation and glory, partly because being feared discourages others from attacking you.
In this condition, Hobbes argues, concepts like justice and injustice simply don’t exist. There’s no right or wrong because there’s no authority to define or enforce it. Every person has a “right to all things,” including the bodies of other people. It’s not that humans are evil by nature. It’s that without a power above them to keep order, rational self-interest drives everyone toward conflict.
Hobbes uses this terrifying picture to justify a very specific political conclusion: people should surrender their freedoms to an absolute sovereign, a ruler or governing body with unchallenged authority. The logic is that any government, even a harsh one, is better than the chaos of no government at all. His first “law of nature” captures this neatly: every person should seek peace when possible, and when peace isn’t possible, use whatever advantages of war they can find. The second law follows from the first: you should be willing to give up your unlimited natural freedom, as long as others do the same, accepting only as much liberty as you’d grant to everyone else.
Locke: A State of Freedom, Not Chaos
John Locke, writing in his Second Treatise of Government (published 1689), agreed that the state of nature existed before government but rejected the idea that it was automatically a state of war. For Locke, people in the state of nature possess natural rights to life, liberty, and property. These rights exist independently of any government or legal system. They come from reason itself, which Locke called “natural law,” a set of moral principles that any rational person can discover without needing a king or a constitution to spell them out.
Locke distinguished natural law from divine law. Natural law applies to all people and can be figured out through reason alone. Divine law requires special revelation and applies only to those who receive it. This distinction mattered because it meant human rights didn’t depend on any particular religious tradition. They were universal.
In Locke’s state of nature, people generally recognize each other’s rights and cooperate. The problem isn’t that humans are inherently violent. The problem is enforcement. When someone does violate your rights (by stealing from you or threatening your life), there’s no neutral judge to settle the dispute. You’re left to defend yourself, and once conflict starts, it tends to escalate because there’s no civil authority to resolve it. This practical problem, not a war of all against all, is the main reason people choose to form governments. Property plays an especially important role here: as people accumulate goods and land, the stakes of disputes grow higher, and the need for impartial courts becomes urgent.
Locke also recognized a general duty to help preserve humankind, including a duty of charity toward those who have no other way to survive. In his framework, rights exist so that people can fulfill their duties to one another, not simply to protect individual self-interest. This is a fundamentally different starting point than Hobbes, and it leads to a fundamentally different kind of government: one that is limited, accountable, and exists to protect natural rights rather than to impose order through fear.
Rousseau: Society Corrupts, Nature Doesn’t
Jean-Jacques Rousseau flipped the entire debate. Writing in the mid-1700s, he argued that human beings are basically good by nature and that it’s civilization, not the absence of civilization, that makes us cruel, competitive, and unequal. In his description of the “pure state of nature,” humans are isolated, timid, peaceful, and mute. They lack the foresight to worry about the future. They aren’t locked in Hobbesian warfare because they don’t have the social structures that create rivalry in the first place.
Rousseau traced a historical arc. As humans began forming societies, they started valuing specialized talents over virtues like courage, generosity, and temperance. The arts and sciences, far from elevating humanity, grew out of our worst impulses: astronomy from superstition, eloquence from ambition and flattery, geometry from greed, physics from vain curiosity. As social complexity increased, strict notions of property emerged, distinct social classes formed, and eventually something very much like Hobbes’s state of war appeared. But for Rousseau, this war was a product of civilization, not nature.
The concept of the “noble savage” is often associated with Rousseau, though his actual argument is more nuanced. He wasn’t saying that humans in nature are simply good and humans in society are simply bad. He was arguing that the socialization process itself produces inequality, competition, and egoism. The state of nature, for Rousseau, represents a baseline of peace and equality that society has steadily eroded.
Why the Concept Still Matters
The state of nature isn’t just a historical curiosity from dusty philosophy books. It remains one of the most influential frameworks in political thought because it forces a basic question: what justifies the power that governments hold over individuals?
If you follow Hobbes, strong central authority is justified because the alternative is catastrophe. If you follow Locke, government is only legitimate when it protects the natural rights people already possess, and citizens can revolt when it fails to do so. (This line of thinking directly influenced the American Declaration of Independence.) If you follow Rousseau, the goal of politics should be to recover the equality and freedom that civilization has stolen from us.
The concept also shows up in international relations theory. Many political realists treat the relationship between nations as a kind of state of nature: there’s no world government enforcing rules, so countries exist in a condition of anarchy. Drawing on Hobbes, these theorists argue that without a common authority above them, states are justified in maximizing their own power to survive. This reasoning has been used to explain arms races, preemptive wars, and the general difficulty of international cooperation. Critics point out that this may oversimplify Hobbes, stripping away the historical context of his ideas and ignoring the moral reasoning he built into his framework, but the analogy remains deeply embedded in how policymakers think about global politics.
Modern Critiques of the Whole Idea
Anthropologists and archaeologists have increasingly challenged the state of nature as a useful concept at all. David Graeber and David Wengrow, in their 2021 book The Dawn of Everything, argue that both the Hobbesian and Rousseauian versions of the state of nature are simply wrong, have harmful political implications, and “make the past needlessly dull.” Drawing on roughly 30,000 years of archaeological evidence, they reject the idea that early humans were either bloodthirsty brutes held in check by authority or peaceful equals corrupted by agriculture and property.
Instead, they present early humans as natural experimenters who consciously tried out different forms of culture and governance. So-called “simple” peoples were, in their view, more politically imaginative than modern societies, not less. The very essence of humanity, they argue, is that we are self-conscious political actors capable of embracing a wide range of social arrangements. Classifying societies by their mode of subsistence (hunter-gatherers vs. farmers, for example) looks naïve in light of the evidence. The process by which cultures define themselves is always political, involving deliberate arguments about the proper way to live.
This critique doesn’t make Hobbes, Locke, or Rousseau irrelevant. Their arguments about rights, authority, and the social contract still shape constitutions, legal systems, and political debates worldwide. But it does challenge the assumption that there was ever a single “natural” human condition from which all of political life flows. The real history of human societies turns out to be far more varied and surprising than any single thought experiment could capture.
