Summary
Leviathan, published in 1651 in the aftermath of the English Civil War, is one of the founding texts of modern political philosophy. Hobbes wrote it under the shadow of a society that had just executed its king and descended into years of violent conflict. His central question was stark: why should anyone accept political authority at all? His answer, built on a materialist account of human nature and rational self-interest, established a framework for thinking about government, sovereignty, and legitimacy that still shapes political theory today.
Hobbes begins with psychology. Human beings are, at bottom, driven by appetite and aversion, seeking pleasure and avoiding pain. Without government, this produces the "state of nature" — a condition of perpetual competition and insecurity where life is "solitary, poor, nasty, brutish, and short." This is not a historical claim but a logical one: remove coercive authority and the result is war of all against all. No one is powerful enough to be secure, so even the strongest has reason to fear.
The solution is the social contract. Rational individuals, calculating that any government is preferable to chaos, authorize a sovereign — a monarch or assembly — to exercise power on their behalf. The key move is that this authorization is irrevocable. Hobbes opposes the idea that citizens can judge when their sovereign has become tyrannical and take action accordingly; that path leads straight back to civil war. The sovereign's authority must be absolute, or it is nothing. The one exception is direct threats to the subject's life — self-preservation is the one right that cannot be surrendered because it is the reason for entering the contract in the first place.
The third and fourth parts of Leviathan, dealing with Christian theology and the Church, were as controversial to contemporaries as the political theory. Hobbes argued that religious authority must be subordinate to the sovereign, and that much of what passed for Christian doctrine was misreading of scripture. The book was denounced as atheist by many readers, though Hobbes himself insisted on his Christianity. Reading Leviathan in full reveals a more systematic — and more theological — thinker than the selective quotations about brutish lives suggest.

Key takeaways
- 1.
Without political authority, the state of nature produces a war of all against all, in which there is no industry, no culture, no society — and life is solitary, poor, nasty, brutish, and short.
- 2.
Human beings are rational calculators of self-interest. It is this rationality, not virtue, that drives them to contract into political society — any order is preferable to the insecurity of the state of nature.
- 3.
The social contract authorizes a sovereign — person or assembly — to exercise power on behalf of all subjects. Crucially, Hobbes argues this authorization must be nearly absolute and irrevocable.
- 4.
Hobbes opposes the right of rebellion: if subjects can judge when their sovereign is tyrannical and act accordingly, the result is civil war, which is worse than any government. Only direct threats to life justify resistance.
- 5.
Sovereignty cannot be divided. Hobbes criticizes constitutional arrangements that split power between king and parliament, arguing they are inherently unstable — a prediction his own era seemed to confirm.
- 6.
Religious authority must be subordinate to political authority. Hobbes argues that the Church's claim to a separate jurisdiction over souls is a recipe for perpetual conflict between church and state.
- 7.
Hobbes's materialism is systematic: he reduces mental states, emotions, and even reason itself to motions in the body. This makes Leviathan as much a work in philosophy of mind as in political theory.
- 8.
The right of self-preservation is the one natural right that cannot be transferred. A subject cannot be obligated to obey a command to kill themselves, because that contradicts the entire point of entering civil society.
Discussion questions
Use these on your own, with a book club, or as chat starters in Superbook.
- 1.
Hobbes describes the state of nature as a thought experiment about what happens when authority breaks down. Can you think of historical or contemporary examples that support or challenge his picture?
- 2.
Hobbes argues any government is better than no government. Do you accept that as an absolute claim, or are there conditions under which the state of nature would be preferable?
- 3.
His model of human nature is self-interested throughout. Is that an accurate description of how people actually behave, or does it miss something important?
- 4.
Hobbes opposes divided sovereignty and checks on the monarch's power. How does that look in light of constitutional democracies — were the constitutionalists wrong, or does experience refute Hobbes?
- 5.
The one exception to obedience is self-preservation. How far does that exception extend? Does it justify resistance against systematic oppression?
- 6.
Hobbes says religious claims to authority over subjects must yield to the sovereign's commands. How do you think about the relationship between political and religious authority today?
- 7.
Leviathan was written during a civil war. How much of Hobbes's argument do you think is shaped by that specific historical context, and how much has permanent philosophical force?
- 8.
Hobbes thinks social order depends on coercive authority, not shared values or culture. Is he right that force is the foundation, or do you think norms and trust do more work than he acknowledges?
- 9.
What would Hobbes say about international relations — the space between states where there is no sovereign? Does his logic apply, and what follows from it?
- 10.
How does Hobbes's social contract differ from Rousseau's? What does the difference tell you about the different problems they were trying to solve?
- 11.
Hobbes was accused of atheism but insisted on his Christianity. Do you think his theology and his political theory are compatible, or does his materialism undercut his religious claims?
- 12.
Where in contemporary politics do you see Hobbesian logic — the argument that order requires concentrating power and limiting challenge to authority?
Themes
Frequently asked questions
-
What is Leviathan about?
Leviathan argues that political authority is justified because the alternative — a state of nature without government — is a condition of perpetual war and insecurity. Rational self-interest leads people to authorize a sovereign, whose power must be nearly absolute to maintain order. The book also covers psychology, religion, and theology.
-
How hard is Leviathan to read?
Challenging. Hobbes writes with unusual precision for his era, but the work is long (around 700 pages in most editions), the theological sections require familiarity with seventeenth-century religious disputes, and some key terms are used in specialized ways. Many readers focus on the first two parts, which contain the core political theory.
-
Is Leviathan a defense of monarchy?
It's a defense of absolute sovereignty, which could be exercised by a monarch or an assembly. Hobbes was personally cautious about which regime he endorsed in print, but his logic most naturally supports strong executive authority rather than parliamentary government.
-
What does 'solitary, poor, nasty, brutish, and short' describe?
The life of humans in the state of nature — Hobbes's hypothetical condition without government or law. The phrase describes the inevitable result of competition among self-interested individuals when there is no coercive authority to enforce peace.
-
Who should read Leviathan?
Students of political theory, philosophy, and intellectual history. For readers who want the core argument without the theological sections, the first two parts stand on their own. Anyone interested in the foundations of arguments about state power and order will find Hobbes still directly relevant.
