Hobbes, Locke, and the Social Contract

dialoguegroups-powerhuman-nature

The social contract tradition — Hobbes, Locke, and their successors — asks the fundamental question of political philosophy: why should anyone accept the authority of a government? The answers Hobbes and Locke give differ profoundly, because they begin with different assessments of human nature. Hobbes' pessimism produces a theory of nearly absolute sovereignty; Locke's conditional trust produces a theory of limited government and the right of revolution. Both are responding to the same real problem: the anarchic baseline from which all political order must be built.

Building On

Rules protect the weak

The social contract is the theoretical foundation of why rules exist. In Level 1, students learned that rules protect the vulnerable from the powerful. Hobbes and Locke are asking the deeper question: why would anyone agree to be governed in the first place? Their answers are the philosophical infrastructure beneath every lesson about rules, fairness, and authority.

Human nature and political possibility

Level 3 established that assumptions about human nature drive political conclusions. Hobbes and Locke are the clearest illustration of this principle at the level of foundational political theory: the same starting question ('what would life be like without government?') produces radically different answers because the two thinkers begin with different assumptions about human beings.

Constitutional design

Madison's constitutional design in Level 4 is Hobbesian in its assumptions about human nature — people in power will pursue self-interest — but Lockean in its objectives: protecting natural rights and making government revocable. Understanding Hobbes and Locke directly illuminates why the American founding documents seem to embody two different theories of government simultaneously.

Why It Matters

Every political system on earth rests on some implicit or explicit theory of why people should obey it. The social contract tradition is the most rigorous attempt in Western political thought to answer that question from first principles — not by appealing to God, tradition, or conquest, but by asking what rational people would agree to if they had to start from scratch.

The debate between Hobbes and Locke is not merely historical. It is the philosophical substructure beneath every contemporary argument about the proper scope of government power. When someone argues that the government's primary obligation is to maintain order and security, they are reasoning as Hobbes did. When someone argues that individuals have rights the government cannot override regardless of the majority's preferences, they are reasoning as Locke did. These traditions are alive in every political argument you will encounter for the rest of your life.

Understanding where your own political instincts come from — and whether they are Hobbesian, Lockean, or some complex mixture — is a prerequisite for thinking clearly about politics rather than simply reacting. Most people hold both sets of assumptions simultaneously without realizing it, which is why political arguments often feel unresolvable: the disputants are reasoning from different foundational premises about human nature and the purpose of government.

A Story

A Thought Experiment About Starting From Nothing

The following is a structured dialogue between two thinkers — drawing on the actual arguments in Hobbes' Leviathan (1651) and Locke's Second Treatise of Government (1689). The historical context matters: both men were writing in the shadow of the English Civil War, a conflict that killed hundreds of thousands of people and ended with a king being publicly executed. The question 'what justifies political authority?' was not academic for them; it was a matter of life and death.

The thought experiment both men use is the 'state of nature' — an imagined condition before any government exists. They are not claiming this is historical; they are using it as a tool to clarify what government is for. By asking 'what would life be like without any authority?', they clarify what authority is supposed to provide.

HOBBES: Imagine the state of nature with complete honesty. There is no law, no police, no courts, no army, no government of any kind. Every person must provide for their own security by their own means. Now ask: what would actually happen? People have roughly equal natural capabilities — the weakest can kill the strongest with a club while he sleeps. And they all want the same things: food, safety, status, comfort. In this condition, there is a 'continual fear and danger of violent death, and the life of man is solitary, poor, nasty, brutish, and short.' This is not a moral judgment about human beings. It is a structural observation: in the absence of common authority, the logic of pre-emptive violence becomes rational for everyone. If I don't attack my neighbor before he attacks me, he has every incentive to attack me first. Security can only be achieved by acquiring enough power to deter everyone else — and since everyone is reasoning the same way, the result is perpetual war.

LOCKE: You are right that the state of nature is dangerous, but you have made a crucial error. You have assumed that without government, there is no law. But there is a law of nature, discoverable by reason, that pre-dates any political institution: no one has the right to harm another in their life, health, liberty, or possessions. People in the state of nature are not beasts; they have reason, and reason reveals the natural law. The state of nature is not a state of war by definition. It becomes dangerous only when some people choose to violate the natural law — which they may do, and which is a genuine problem. But the baseline is not Hobbes' war of all against all. It is a condition of rough equality and natural rights, which becomes practically unstable because there is no impartial arbiter to settle disputes.

HOBBES: Your natural law is wishful thinking. You are assuming that people will recognize it and be governed by it, but the experience of history shows that people are perfectly capable of convincing themselves that whatever they want to do is consistent with reason and morality. The man who steals from me will tell himself it was justified. The man who kills me will have constructed a philosophical justification. Without an external authority to enforce the law, the law is simply the preference of the stronger. Your state of nature is a comfortable fiction. Mine is an accurate prediction.

LOCKE: And your solution is the real danger. You argue that because the state of nature is bad, we should accept any sovereign who is strong enough to impose order — including an absolute monarch with no limits on his power. But you have only moved the problem: who protects us from the sovereign himself? The absolute monarch is also a human being, subject to the same passions and self-interest as everyone else. You have escaped the foxes only to submit to a lion. The only legitimate government is one that is limited — that governs with the consent of the governed, that protects natural rights rather than violating them, and that can be removed when it fails to do so. A government that systematically violates the rights of its subjects has dissolved the contract, and the people retain the right to replace it.

HOBBES: And there is your problem. The right to judge when the sovereign has violated the contract, and the right to replace him — who exercises that right? The individual? Every faction that dislikes the government? The moment you admit the right of revolution based on individual or factional judgment, you are back in the state of nature. Civil war is the state of nature with flags. I would rather have a sovereign too strong than a perpetual war of factions, each claiming the natural law justifies their rebellion. The cost of your liberty is the stability you are taking for granted.

Vocabulary

State of nature: A thought experiment used by social contract theorists to clarify the purpose of government by imagining human life without any political authority. Hobbes sees it as necessarily a state of war; Locke sees it as a condition of natural freedom and rough equality that becomes practically unstable but is not inherently violent.
Social contract: The implicit or explicit agreement by which individuals surrender some natural freedom to a political authority in exchange for security, impartial justice, or the protection of rights. The foundational concept of modern political legitimacy: governments derive their authority from the consent of the governed.
Natural rights (Locke): Rights that individuals possess prior to and independent of any political institution — in Locke's formulation, life, liberty, and property. These rights are not granted by government but recognized by it; a government that systematically violates them forfeits its legitimacy.
Sovereignty (Hobbes): The supreme, undivided, and unchallengeable authority of the Leviathan — the political body created by the social contract. For Hobbes, sovereignty must be absolute and indivisible, because any limitation on sovereign authority creates the conditions for factional conflict and civil war.
Right of revolution: Locke's argument that a people may legitimately overthrow a government that systematically violates their natural rights, having dissolved the original contract by its own actions. The philosophical basis for both the American Declaration of Independence (1776) and the French Revolution (1789).

Guided Teaching

Begin with the shared starting point. Both Hobbes and Locke are responding to the same historical catastrophe — the English Civil War — and asking the same fundamental question: what justifies political authority? Ask your student: 'What is the weakest possible answer to that question?' The weakest answers are: 'because God said so,' 'because it's always been this way,' and 'because the king is stronger than you.' Social contract theory is an attempt to give a stronger answer — one that doesn't depend on theology, tradition, or force alone. Ask: 'Why would people in 17th-century England, having just executed their king, want a better answer to that question?'

The state of nature is a thought experiment, not a history. Make sure your student understands this. Neither Hobbes nor Locke is claiming that people actually lived in this condition before civilization. They are using it as an analytical tool: if you strip away all political authority, what remains? And what does that tell you about what political authority is supposed to provide? Ask: 'What does your answer to the state-of-nature question depend on? What assumptions about human nature are you making when you answer it?' This is the key diagnostic: the Hobbesian and Lockean answers diverge precisely at the point where they make different assumptions about what people are like.

Take Hobbes seriously. Students often want to dismiss Hobbes as extreme, but his core observation — that security is the precondition for everything else, and that the logic of pre-emptive attack is rational in the absence of common authority — is difficult to refute. Ask: 'Can you think of real examples from history or current events where the absence of effective government produced Hobbes' predicted outcome: a war of all against all?' Failed states, civil wars, and the international system (where no overarching sovereign exists) are all relevant. The point is that Hobbes is not simply describing his own pessimism; he is describing a real structural dynamic.

Take Locke's challenge to Hobbes seriously. Locke's key point is that Hobbes has only relocated the problem: the absolute sovereign is as dangerous as the state of nature. Ask: 'What historical evidence would Locke cite for this claim?' The 20th century provides overwhelming evidence: Stalin's Soviet Union, Hitler's Germany, Mao's China. Each was a powerful sovereign who had solved the problem of disorder by imposing absolute control — and each produced suffering vastly exceeding anything that could be attributed to a state of nature. Does this vindicate Locke? Or would Hobbes say that these regimes were simply preferable to the civil wars they replaced?

Connect to the American founding. The Declaration of Independence is a Lockean document: governments derive their just powers from the consent of the governed, and when a government becomes destructive of natural rights, the people have the right to alter or abolish it. But the Constitution reflects Hobbesian lessons: it creates a strong central government because the Articles of Confederation — the closest thing to Locke's limited government — had failed to maintain order. Ask: 'Is the American system fundamentally Hobbesian, Lockean, or an attempted synthesis? Which premise seems to win in practice?' This question has no clean answer, which is the point.

Pattern to Notice

Notice how different assumptions about human nature produce radically different political conclusions from exactly the same starting question. Hobbes and Locke both ask 'what would life be like without government?' and reach opposite conclusions — not because they are reasoning differently, but because they have different empirical assumptions about what people are like. This is the pattern underlying almost every major political disagreement: people who argue about policy are often arguing about political philosophy, and people who argue about political philosophy are often arguing about human nature. Getting to the real disagreement requires asking not just 'what do you think the policy should be?' but 'what do you think people are like?'

A Good Response

The wisest position is not to simply choose Hobbes or Locke but to recognize what each one got right. Hobbes is correct that security is the precondition for everything else, that the logic of the security dilemma is real, and that stable order requires an authority capable of enforcing rules. Locke is correct that concentrated power without accountability is itself a threat to the security and rights it is supposed to protect. The challenge of constitutional design — which Level 4 explored — is precisely the challenge of maintaining enough sovereign authority to prevent chaos while maintaining enough constraint to prevent tyranny. There is no formula that resolves this tension; there is only the ongoing work of maintaining institutions that hold it in productive balance.

Moral Thread

Justice

Both Hobbes and Locke are asking the same foundational question about justice: what do we owe each other, and why? Their different answers flow directly from different assumptions about human nature — and that means the question of justice cannot be separated from the question of what kind of creatures we are. Justice is not a free-floating ideal; it is a response to the specific needs and vulnerabilities of beings like us.

Misuse Warning

Both Hobbes and Locke have been misused to justify opposite extremes. Hobbesian logic has been used to justify authoritarian regimes on the grounds that order requires absolute power — forgetting that the sovereign himself is the greatest threat to order. Lockean logic has been used to justify the dismantling of effective institutions on the grounds that any government power is a threat to natural rights — forgetting that the absence of effective authority produces the very disorder that makes life impossible. The real lesson is that both dangers are real, that the tension between them is permanent, and that any political arrangement that pretends to have permanently resolved it is either naive or dishonest.

For Discussion

1.Hobbes argues that the state of nature is necessarily a war of all against all. Locke argues it is merely unstable. Which view seems more accurate to you, based on what you know of human history and behavior? What evidence would change your mind?
2.Locke argues that people have the right to revolution when their government systematically violates their rights. What are the dangers of this argument? How do you distinguish a legitimate revolution from a factional rebellion using the language of natural rights?
3.The American Declaration of Independence is a Lockean document, but the Constitution reflects Hobbesian lessons about the need for strong central authority. Is this a contradiction — or an attempt to synthesize two genuinely valid insights?
4.Both Hobbes and Locke were writing in the aftermath of the English Civil War. How does that historical context shape their theories? What might they have said if they had been writing in the aftermath of a different catastrophe — say, an absolute monarchy that had produced famine and oppression?
5.If Hobbes and Locke could read the 20th century's history of totalitarian states, what would each conclude? Would the evidence change their arguments in any way?

Practice

The State of Nature Test

1.Think of a real situation — historical or contemporary — where effective government authority has broken down or been absent: a failed state, a region during civil war, an area after a natural disaster before emergency services arrive, or any other example.
2.Analyze the situation through both lenses:
3.1. The Hobbesian analysis: Was there a security dilemma? Did the absence of common authority produce pre-emptive violence? Did the logic Hobbes described play out?
4.2. The Lockean analysis: Did people maintain natural-law-like norms even in the absence of formal authority? Were there informal mechanisms of cooperation and mutual protection? What does this evidence say about Locke's view of human nature?
5.Write 300–400 words describing what you found. Does the evidence from your example favor Hobbes or Locke — or does it suggest that both are partially right in different circumstances?
6.Discuss with a parent: what assumptions about human nature did you bring to this exercise before you started? Did the analysis change them in any way?

Memory Questions

1.What is the state of nature, and why do Hobbes and Locke use it as a thought experiment?
2.Why does Hobbes conclude that the state of nature is a war of all against all?
3.What is Locke's critique of Hobbesian absolute sovereignty?
4.What are Locke's natural rights, and what does it mean for a government to violate them?
5.How does the tension between Hobbes and Locke show up in the American founding documents?

A Note for Parents

This is the most philosophically technical lesson in Level 5, and it requires the parent to be willing to sit with genuine disagreement rather than resolve it artificially. Hobbes and Locke are both right about important things, and the tension between their views is not resolvable by simply choosing one. The dialogue format is designed to model rigorous philosophical argument — the genuine engagement with opposing positions that real intellectual work requires. The key teaching move is to push back when your student tries to dismiss either thinker: 'But Hobbes is just a pessimist' or 'But Locke is obviously right about rights.' Both dismissals avoid the real argument. The connections to Level 1 (rules protect the weak) and Level 4 (constitutional design) should be made explicit: this lesson is the philosophical foundation that runs beneath the entire curriculum.
