Grading Essays on Natural Rights: Life, Liberty, and Property in Locke
Published on September 29th, 2026 by the GraideMind team
Ask a class what Locke believed and you will hear the same answer: life, liberty, and property. It is a fair summary, but it is also the point where most essays stop thinking. Teachers who want students to go further need prompts and rubrics that require them to explain what these rights mean and where they come from. That takes grading criteria built for depth and not recall.

Locke does not treat natural rights as arbitrary claims. He grounds them in natural law, which he says reason can discover, and in the idea that people are the workmanship of God and therefore not to be treated as the property of others. Students who skip this foundation often write as if rights simply exist. Strong essays explain why Locke believes they do, and what follows if the explanation fails.
It also helps to note that Locke often uses property in a broad sense that includes life and liberty as well as material goods. Students who read the term narrowly may accuse him of caring only about wealth. Noticing the broader use is a mark of careful reading. Feedback can point to the relevant passage and ask how it changes the interpretation.
Moving Beyond the Slogan
A good prompt asks students to test the idea. Do natural rights limit what a majority may do, or only what a monarch may do? Are rights given up when people enter civil society, or retained? Locke says people give up the executive power of the law of nature but keep their basic rights, and essays that grasp this distinction are on solid ground. Answering these questions requires close reading.
- Explains the source of natural rights in Locke's theory of natural law
- Distinguishes which powers people give up and which rights they keep in civil society
- Recognizes Locke's broad use of the term property
- Considers at least one objection, such as who is actually protected by these rights
- Supports claims with specific passages and not general impressions
Students understand natural rights better when they have to explain where the rights come from, not just list them.

One common mistake is presenting natural rights as purely secular. Locke's argument relies heavily on religious premises, and essays that ignore this can distort his position. Another error is treating rights as absolute, when Locke allows that the community may regulate their exercise for the public good under certain conditions. Feedback should ask students to check their claims against the text.
A third problem is assuming that Locke's rights apply equally to everyone in his own society. His writings and his political involvements complicate that picture, and thoughtful essays acknowledge the tension. Students need not resolve it, but they should notice it. Rewarding this awareness pushes essays toward greater honesty.
Aligning Rubrics With Depth
To reward depth, weight the rubric toward explanation and evaluation rather than definition. Give a smaller share of points to correctly naming the rights and a larger share to explaining their basis, limits, and consequences. This signals to students that memorization is not enough. It also lets you differentiate among essays that all get the basics right.
When grading many essays, apply the same weights consistently and record notes on recurring issues. If half the class ignores the religious foundation of natural rights, that is a teaching point for the next lesson. Tools like GraideMind can surface such patterns by applying your rubric to every paper. You then use the patterns to guide instruction.
Encouraging Modern Connections
Natural rights language remains central to modern debates about human rights, privacy, and government power. Students can write compelling essays connecting Locke to these themes, provided they stay grounded in his actual arguments. Ask them to explain how a modern claim differs from Locke's and where it might extend beyond his framework. This makes the connection analytical.
The goal is for students to leave the unit with more than a slogan. They should be able to explain what Locke meant, why he thought it, and where his theory might be challenged. Essays that reach that standard show real learning, and a rubric that rewards it helps make it happen.
