This guide focuses on Chapter 5 of the Second Treatise, a core text for political philosophy and literature courses that explore ideas of ownership, individual rights, and government legitimacy. It is designed to help you prepare for in-class discussion, short quizzes, and longer analytical essays. No prior philosophy background is required to use the materials here.
Chapter 5 of the Second Treatise centers on the origins of private property, arguing that individual labor applied to natural resources creates legitimate ownership outside of formal government structures. It addresses how property is accumulated, limited, and transferred before the establishment of formal legal systems, and it lays foundational ideas that shape later conversations about individual rights and state power.

Second Treatise Chapter 5 is the section of the political philosophy text that outlines the labor theory of property, the core argument that mixing one’s personal work with unowned natural resources gives that person a right to claim that resource as private property. The chapter also establishes limits to property accumulation, including the requirement that no resources are wasted and enough resources are left for other people to claim for their own use.
Next step: Write a 1-sentence summary of the chapter’s core argument in your own words to confirm you understand the core premise.
Action: Review the key takeaways and quick answer to identify the core claims you will look for as you read the full chapter.
Output: A set of 2-3 margin notes flags you will use to mark passages that address property limits, labor as ownership, and the role of money.
Action: Read the full chapter, marking passages that align with your pre-identified flags and writing 1-sentence margin notes for each marked section.
Output: An annotated copy of the chapter with clear labels for each of the 4 key takeaways listed in this guide.
Action: Compare your annotated notes to the study guide materials, then update any notes where your initial interpretation differs from the guide breakdown.
Output: A 1-page cheat sheet with the core argument, key limits to property, and 2 short examples of legitimate property acquisition from the text.

Action: Break the chapter into 4 sections: premise about natural resources, explanation of labor as ownership source, outline of property limits, discussion of money’s impact.
Output: A 4-bullet outline that lists the main claim of each section in your own words.
Action: Pick a common modern property item, such as a grown vegetable or a handmade craft, and apply the chapter’s rules to determine if it counts as legitimate property under the text’s framework.
Output: A 3-sentence analysis that states whether the item meets the text’s criteria and explains your reasoning.
Action: List 2 conditions the chapter assumes are true for its property rules to work, such as the existence of unclaimed land for people to mix their labor with.
Output: A 2-sentence note for each assumption that explains how the argument would change if that assumption was not true.
Teacher looks for: A clear explanation of the labor theory of property that includes the natural limits to accumulation and the role of money, with no major misinterpretations of the text’s claims.
How to meet it: Cross-check your summary against the key takeaways and common mistakes list to make sure you are not misrepresenting any core claims, and explicitly name both natural limits to property in your summary.
Teacher looks for: Recognition that the chapter’s arguments were written for a specific 17th-century European context, and that its assumptions may not apply to other cultural or historical contexts.
How to meet it: Include at least one sentence in your essay or discussion answer that names an unstated assumption of the argument, such as the existence of unclaimed land, and note how that assumption is tied to the historical context of European colonization.
Teacher looks for: Explicit links between the property arguments in Chapter 5 and the text’s broader claims about the purpose and limits of legitimate government.
How to meet it: Add one sentence to your conclusion that explains how the government’s duty to protect property rights, outlined later in the text, directly stems from the property rules laid out in Chapter 5.
The chapter starts from the premise that the natural world is originally held in common for all people to use for survival. It argues that when a person applies their own labor to a natural resource — for example, farming unplanted land or gathering wild fruit — they mix that labor with the resource, making it their private property. Use this breakdown as a reference when drafting discussion notes or quiz answers.
The text places two non-negotiable limits on how much property a person can rightfully claim through labor. First, a person cannot take more resources than they can use before they spoil, to avoid wasting resources that other people could have used. Second, a person must leave enough and as good of the same resource for other people to claim for their own survival needs. Jot down these two limits on your chapter cheat sheet to reference during class.
The chapter explains that the invention of money, which holds its value over time and does not spoil, allows people to accumulate more property than they can personally use without violating the spoilage limit. People can trade perishable goods for money, which they can store indefinitely, and use that money to acquire more property later. This part of the argument is often tested on multiple-choice quizzes, so highlight it in your notes.
The property rules laid out in Chapter 5 form the foundation for the text’s later arguments about the purpose of legitimate government. The text argues that people form governments primarily to protect their pre-existing natural property rights, not to create property rights out of nothing. Use this before class to connect Chapter 5 content to earlier or later sections of the text you have already read.
One frequent misinterpretation of the chapter is the claim that it argues property rights only exist after formal government is established. The text explicitly states that property rights exist in the state of nature, before any government is formed, and that government’s job is to protect those pre-existing rights. Check your notes against the common mistakes list in the exam kit to make sure you have not fallen for this error.
The arguments in this chapter are still referenced in modern debates about land ownership, intellectual property, and labor rights. For example, conversations about who owns content created by gig workers or social media creators often draw on the core idea that labor creates ownership rights. Pick one modern debate that interests you and draft a 2-sentence note about how Chapter 5 ideas apply to that debate.
No, Chapter 5 focuses specifically on the origin of private property in the state of nature before government is formed. The text’s discussion of government origins comes in later chapters, but the property arguments in Chapter 5 lay the foundation for those later claims.
No, the chapter explicitly outlines two natural limits to property accumulation: no spoilage of owned resources, and enough resources left for other people to use. The invention of money only makes the spoilage limit easier to bypass, it does not eliminate either limit entirely.
You can understand the core arguments of Chapter 5 on its own, but reading the earlier chapters about the state of nature and later chapters about government will help you see how the property arguments fit into the text’s broader political philosophy framework.
The labor theory of property is the core argument that when a person mixes their own personal labor with an unowned natural resource, that labor gives them a legitimate right to claim that resource as their private property, separate from any formal legal or royal approval.
