Second Treatise of Government
John Locke (1632–1704)
True liberty requires that we govern ourselves through consent rather than force. Discover why the original social contract remains the only legitimate foundation for any just and enduring civil society.
The Story
The progression of this work begins in the foundational concept of the "state of nature," a condition of perfect freedom and equality where individuals exist without a common superior. In this original state, every person is bound by the law of nature, which dictates that no one ought to harm another in their life, health, liberty, or possessions. Because this law is intelligible to any rational creature, every individual possesses the executive power to punish those who transgress it. However, this state is inherently inconvenient. Because men are often biased in their own favor or driven by passion and revenge, the lack of an impartial judge leads to inevitable disorder. Civil government, therefore, emerges as the necessary remedy to these inconveniences, established not by divine decree or paternal inheritance, but through the deliberate, voluntary consent of free individuals.
The narrative of this political evolution moves quickly from this initial state to the creation of property. In a world provided by nature for the common use of mankind, a person acquires exclusive rights to a resource by mixing their own labor with it. By removing an object from the common state and applying industry, the laborer makes that object part of themselves, thereby excluding the claims of others. This is the origin of private dominion. As societies grow, the pursuit of comfort and the desire to protect these accumulated fruits of labor drive men to leave the state of nature. They do not do this to surrender their rights, but to better secure them. By uniting into a commonwealth, they delegate the power of interpreting the law and punishing transgressors to an organized legislative and executive body.
The arc of the argument then turns toward the internal mechanics of this newly formed society. The power held by the government is strictly fiduciary; it is a trust reposed in the rulers for the sole purpose of protecting the members of the society and their property. The legislative power—the supreme authority—cannot be transferred to other hands, nor can it legitimately tax the people without their consent, either given directly or through their chosen representatives. The laws must be established, promulgated, and applied equally to rich and poor alike. The focus here is on the preservation of the public good. If the government fails in this duty—if it acts to impoverish, harass, or subdue its citizens—it ceases to be a legitimate authority and becomes a tyranny.
The conclusion of this progression deals with the dissolution of government. When a ruler uses force without right, they put themselves into a state of war with the people. At this point, the government effectively dissolves, and the power reverts to the community. The people are then authorized to defend themselves against the aggressor. While the author acknowledges that such situations are grave and not to be undertaken lightly, he argues that the right to resist tyranny is as fundamental as the right to self-preservation. When the laws are transgressed to the harm of the public, or when a ruler attempts to place the society under the subjection of a foreign power, the trust is broken. The people, having originally lodged the power in the government, reserve the right to judge when that trust has been forfeited and to erect a new form of government in its place.
The People
- The Individual in the State of Nature: The protagonist of the argument, this person is defined by rationality and the inherent freedom to dispose of their own person and property. They seek to escape the uncertainty of a world without judges and voluntarily trade a portion of their natural liberty for the security of a collective society.
- The Legislator/Magistrate: An agent of the people who holds a delegated trust. They are authorized to create laws and enforce justice, but they are strictly bound by the same natural laws that govern everyone else. Their legitimacy depends entirely on the consent of the governed and their adherence to the public good.
- The Tyrant: A figure who abandons the role of a legitimate magistrate by making their own will the supreme law. By exceeding the power granted by the social compact, they revert to a state of nature where they have no authority, effectively inviting the resistance of those they were meant to protect.
- The Parent: Often misunderstood as a model for political power, the parent holds authority only during the period of a child’s "ignorant nonage." Once the child reaches the age of reason, this authority expires, proving that paternal power is a temporary duty of care rather than a permanent right to command or own.
In Its Own Voice
The author emphasizes that the very act of joining a society is a deliberate choice made by free men to resolve the problems of the state of nature:
The beginning of any political society, is nothing but the consent of any number of freemen capable of a majority to unite and incorporate into such a society.
He clarifies that the ruler is not a master, but a servant of the law, and that any departure from this principle results in the loss of authority:
Where-ever law ends, tyranny begins, if the law be transgressed to another’s harm; and whosoever in authority exceeds the power given him by the law, and makes use of the force he has under his command, to compass that upon the subject, which the law allows not, ceases in that to be a magistrate.
Finally, he asserts that the fundamental right of a people to protect themselves from systemic injustice cannot be stripped away:
Therefore all kings that are not tyrants, or perjured, will be glad to bound themselves within the limits of their laws; and they that persuade them the contrary, are vipers, and pests both against them and the commonwealth.
What It's Really About
At its core, this book is an inquiry into the limits of political authority. It moves away from the then-prevalent arguments that kings held power by divine right or paternal inheritance, replacing them with a framework built on human reason and property rights. The central question is: under what conditions is obedience to the state mandatory, and when does it become a moral failing?
The argument rests on the assumption that individuals have inherent rights—specifically life, liberty, and estate—that exist prior to the formation of any government. These rights are not granted by kings; they are recognized by the law of nature. Consequently, the government is not a source of rights, but a tool for their protection. The "social contract" is the mechanism by which the individual, fearing the "inconveniences" of the state of nature—primarily the lack of an impartial judge—agrees to abide by the decisions of a majority.
The text is deeply concerned with the definition of property. By linking property to labor, the author creates a moral justification for ownership that is independent of royal grants. This theme is essential to the argument because it provides a standard by which to measure government overreach. If the state takes property without consent, it violates the very reason for its existence. Thus, the protection of property becomes a proxy for the protection of individual sovereignty.
Furthermore, the book explores the nature of political dissolution. It argues that government is not an end in itself, but a means to an end. When the government turns its force against the people, it effectively declares war on the very constituency it was created to serve. By framing the relationship between the ruler and the ruled as a fiduciary trust, the author places the ultimate power of judgment in the hands of the people. It is a radical assertion that the community, as a whole, remains the final judge of whether the government is fulfilling its purpose. It denies the possibility of absolute, unaccountable power, asserting that even the highest magistrate is subject to the same fundamental laws that protect the day-laborer. Ultimately, this work is a defense of the rule of law as the only barrier between a stable society and a state of perpetual, arbitrary conflict.
Why Read It Today
Reading this work is an exercise in encountering the bedrock of modern political discourse. It is not a casual read; the prose is dense, formal, and structured with a lawyerly rigor that demands full concentration. You will encounter 17th-century sentence structures and a reliance on logic that assumes you are familiar with the debates of its time. However, the effort required to parse these passages is rewarded by the clarity with which the author dismantles the idea that rulers are inherently superior to those they govern.
Modern readers will find the discussion of "property" and "labor" remarkably familiar, as these concepts continue to shape contemporary views on economics and individual rights. While the author’s references to "the wild Indian" and his assumptions about the "state of nature" reflect the colonial perspectives of his era, the underlying arguments regarding the illegitimacy of arbitrary power remain striking. You will likely find yourself reflecting on how often we today use the language of "consent" and "fiduciary duty" when discussing public office, often without realizing how precisely these concepts were articulated here.
You will find the book stays with you because it forces a confrontation with your own assumptions about obedience. It does not provide an easy path to anarchy; rather, it sets a very high, precise bar for what constitutes a legitimate government. It leaves the reader with a sober understanding of the fragility of civil society. When you finish, you are left with the persistent, uncomfortable question the author poses: if the law is silent or if the magistrate acts beyond their trust, who is left to judge? The answer provided—that the appeal lies to heaven, and that the individual must decide when to take that appeal—is one of the most powerful and demanding conclusions in political philosophy. It is a reminder that the responsibility for a just society does not rest with the governors, but with the governed.
