Why Hobbes Believes a Sovereign is Necessary for a Stable Society

What stops society from collapsing into chaos? For Thomas Hobbes, the 17th-century English philosopher, the answer was a single, overwhelming authority he called the sovereign. Writing during the bloodshed of the English Civil War, Hobbes was convinced that human beings, left to govern themselves, would tear each other apart. His solution was bold and uncompromising: only an all-powerful ruler could hold a community together. To understand why he believed this, we need to follow his reasoning from human nature, through the agreement that creates society, to the towering figure of the sovereign who keeps it all standing.

The roots of the problem: human nature 🔗

Hobbes built his entire political theory on a particular view of what humans are like. He believed people are driven primarily by their appetites and aversions, constantly seeking what satisfies them and avoiding what threatens them. The most striking part of his account is the claim that humans share a “restless desire” for power that never stops. In his words, there is a perpetual and restless desire of power after power that ceases only in death.

This is not because Hobbes thought everyone was simply greedy or evil. The desire for power is rational. Power, for Hobbes, is a person’s present means to secure some future good, so accumulating it is a sensible way to guarantee one’s own survival and comfort. The problem is that everyone is doing this at the same time, and the resources people want are limited. When two individuals desire the same thing that only one can have, they become rivals.

Why competition turns into conflict 🔗

Hobbes identified three principal causes of conflict that flow from human nature. The Internet Encyclopedia of Philosophy summarises them clearly: competition, distrust, and glory drive people against one another. Competition arises over scarce goods. Distrust, or what Hobbes called diffidence, arises because no one can be sure of another’s intentions, making a pre-emptive attack the safest strategy. Glory arises from the human craving for recognition and respect, which pushes people to dominate others.

Crucially, Hobbes argued that humans are roughly equal in their ability to harm one another. Even the physically weakest person can kill the strongest, whether through cunning or by joining with others. This equality of vulnerability is what makes the situation so dangerous, because no one is ever truly safe.

The state of nature: life without a common power 🔗

To show why a sovereign is necessary, Hobbes asked his readers to imagine a condition with no government, no laws, and no authority to enforce order. He called this the state of nature. Britannica describes it as a condition defined by the “war of every man against every man”, a constant and violent competition in which each individual has a natural right to everything.

In this condition there is no industry, no agriculture, no trade, and no security, because the fruits of any effort can be seized at any moment. Hobbes summed up the result in one of the most quoted lines in political philosophy: human life would be solitary, poor, nasty, brutish, and short. Importantly, he did not necessarily mean people are fighting all the time. The Stanford Encyclopedia of Philosophy notes that the state of war exists wherever there is a known disposition to conflict with no assurance of peace. The mere readiness to fight, the absence of any guarantee of safety, is enough to make life unbearable.

No justice without authority 🔗

One of Hobbes’s most provocative claims is that in the state of nature, ideas of right and wrong simply do not apply. Where there is no common power, he argued, nothing can be unjust because the notions of justice and injustice have no place. Without an authority to define and enforce rules, morality cannot function as a binding standard. This sets up the central question: how do we escape this misery?

The social contract and why it needs enforcement 🔗

Hobbes argued that reason itself shows the way out. Every rational person can see that endless war frustrates all their goals, so peace is desirable. From this follows what he called the laws of nature, the first of which is to seek peace. To achieve peace, individuals must give up their unlimited right to everything and transfer that right to a common authority. This mutual agreement is the social contract.

Britannica explains the structure of this agreement: political authority rests on a hypothetical contract among the many that vests in a sovereign the responsibility for the safety and well-being of all. People agree among themselves to surrender their natural rights in exchange for protection. The sovereign that results can be a monarch, a legislature, or almost any other form of authority capable of providing security.

The flaw a contract alone cannot fix 🔗

Here lies the heart of Hobbes’s argument for a sovereign. A promise on paper changes nothing if there is no power to enforce it. Because people remain driven by the same restless desire for power even after agreeing to the contract, their ambitions continue to threaten stability. Anyone could calculate that breaking the agreement serves their interest, and if enough people think this way, the whole arrangement collapses back into the state of nature.

This is why Hobbes insisted on a coercive authority. As one analysis of his reasoning puts it, peace requires “a common power to keep them in awe” with the right and force to compel performance of agreements. Covenants without the sword, in Hobbes’s famous phrase, are merely words. The sovereign supplies the sword.

The role of the sovereign in maintaining order 🔗

Once established, the sovereign performs several essential functions that no one in the state of nature could provide. Together these functions transform a frightened, scattered multitude into an organised commonwealth.

Enforcing laws. The sovereign creates clear rules of acceptable behaviour and punishes those who break them. Because Hobbes believed people would violate agreements whenever it suited them, he justified the need for a powerful authority with the power to punish those who break the contract. The threat of punishment is what makes the laws effective.

Resolving disputes. The sovereign acts as the final judge in conflicts between citizens. By providing an authoritative way to settle disagreements, the sovereign prevents private quarrels from escalating into the violence that defined the state of nature.

Defending against external threats. Beyond keeping internal peace, the sovereign protects the commonwealth from outside enemies. The whole point of the arrangement, as Britannica notes, is that government functions primarily as a device for ensuring collective security, both within the community and against rival states.

The Leviathan: an artificial giant 🔗

Hobbes gave this sovereign power a memorable name: the Leviathan, borrowed from the biblical sea monster. The image is deliberate. By submitting to a single overwhelming authority, individuals create what Hobbes saw as an artificial person, far stronger than any of its members, capable of overawing them all and compelling them to keep the peace. The famous frontispiece of his book shows a giant figure whose body is composed of countless tiny individuals, capturing the idea that the strength of the sovereign comes from the people who constitute it.

Why the sovereign must be absolute 🔗

Hobbes did not stop at saying we need a sovereign. He argued that the sovereign’s power must be absolute, meaning it should be indivisible, unlimited, and not subject to any higher authority or legal constraint. This is one of the most controversial parts of his thought, and it follows directly from his fear of the state of nature.

The logic is about indivisibility. Hobbes despised the idea of a mixed or divided government. If power were split between competing institutions, those institutions would eventually clash, and a struggle for supremacy would reopen the door to civil war. An analysis of Leviathan notes that for Hobbes the sovereign’s great authority must be indivisible, derived from being a single political entity. Divided power, in his view, is no real power at all.

Fear as the foundation of obedience 🔗

What ultimately holds the commonwealth together, in Hobbes’s account, is fear of the sovereign’s authority. People comply with the law not primarily out of goodwill but because they know that breaking it carries consequences. This fear is what keeps the restless human desire for power in check. The same instinct for self-preservation that made the state of nature so dangerous now works in favour of order, because each individual fears the punishment the sovereign can deliver.

This produces a sobering conclusion that scholars often highlight. Because the sovereign’s job is to prevent a relapse into war, Hobbes leaves citizens with very little room to resist. The subjects must obey, even when they disagree, because the only alternative is a return to the war of all against all. The single exception is self-preservation itself: if the sovereign can no longer protect a person’s life, the reason for obedience disappears. As one summary of Hobbes’s theory observes, unless the sovereign fails to protect us, we have a duty to obey completely.

The lasting significance of Hobbes’s argument 🔗

Hobbes’s case for the sovereign is uncomfortable, and that is partly why it remains so influential. He stripped away comforting ideas about natural human goodness and asked a hard question: what is the minimum power required to keep people from destroying one another? His answer, an absolute and undivided authority, shaped centuries of debate. Thinkers like Locke and Rousseau adopted his social-contract method while rejecting his bleak conclusions, building theories of limited government and popular sovereignty in direct response.

Even today, Hobbes speaks to enduring concerns. His insistence that security is the first job of government, that order must come before liberty can be enjoyed, echoes in debates about state authority, emergency powers, and the balance between freedom and safety. Whether or not one accepts his demand for an absolute ruler, his core insight is hard to dismiss: without some power capable of enforcing the rules, agreements remain fragile and peace remains uncertain.

What do you think? Is Hobbes right that fear of authority is the real foundation of social order, or can a stable society be built on trust and cooperation alone? And if a sovereign must be powerful enough to keep the peace, where should we draw the line before that power becomes a threat in itself?
