Few assignments in political philosophy are as common as the Locke and Hobbes comparison. It is also one of the easiest essays to write in a shallow way, since students can list differences from a chart without ever building an argument. Teachers who grade these essays repeatedly know how quickly the responses start to blur together. A tighter rubric helps you reward the papers that actually compare and not just describe.

A real comparison identifies a central difference and explains what follows from it. For Locke and Hobbes, that difference is often the character of the state of nature and what it implies about the purpose of government. Hobbes sees a war of all against all that only an absolute sovereign can end, while Locke describes a condition governed by natural law that government exists to protect. An essay that traces how this difference shapes their views on rebellion is doing comparative work.

Weaker essays alternate between the two thinkers without ever putting them in conversation. They describe Hobbes for a paragraph, describe Locke for a paragraph, and then conclude that they disagree. Grade these as summaries with a comparison label attached, and tell students what is missing. A short comment asking what the two theories would say about the same case is often enough to redirect them.

Look for a Shared Question

The strongest comparisons begin with a question both thinkers answer, such as why people should obey a government at all. Framing the essay this way forces the student to treat each theory as an answer, which makes the differences meaningful. Students might argue that both authors start from individual consent, yet Hobbes treats that consent as nearly irrevocable while Locke keeps it conditional. This kind of thesis shows understanding beyond memorized contrasts.

• Identifies a shared question that both thinkers address
• Explains the differing views of human nature with textual support for each
• Connects the state of nature to each thinker's view of sovereignty
• Addresses the right of resistance, where the two diverge most sharply
• Reaches a judgment about which account is more persuasive and why

Avoiding Caricature

Students often flatten both thinkers into slogans, calling Hobbes pessimistic and Locke optimistic. That shorthand hides real complexity, since Locke acknowledges that many people will violate natural law and that a judge is needed for that reason. Hobbes, meanwhile, offers a careful argument about equality and fear, and not merely a dark view of people. Grades should reflect whether the student engages with the argument or leans on the label.

A useful comment prompts students to find a place where their portrait of each author is challenged by the text. Ask them to locate a passage where Locke sounds less hopeful or where Hobbes sounds more reasonable than the stereotype suggests. Even a short revision addressing this tension makes the essay more honest. It also teaches a habit that will serve them in any kind of critical reading.

Fairness Across Many Papers

Because so many students write on the same pairing, essays begin to look alike, and graders can drift toward rewarding polish over substance. One remedy is to sort papers into rough bands after reading a small sample, then check the bands again halfway through the stack. Another is to weight the thesis and comparative structure more heavily than sentence-level style. Both methods keep scoring aligned with the goals of the assignment.

AI feedback tools like GraideMind can apply a written rubric consistently across a large pile, flagging where a comparison is missing or where evidence is thin. That gives you a starting point for each essay, which you can accept or override based on your own reading. The key is that your criteria, not the tool's defaults, define what a strong comparison looks like. Clear criteria make the whole process more transparent for students as well.

Helping Students Revise

Revision is where the comparison assignment pays off. Ask students to rewrite their thesis after seeing your comments, this time naming the one difference that matters most and the consequence it produces. Many will find that their original thesis was really just a list. The second version usually shows a clearer argument and a more purposeful use of evidence.

Over time, students who practice this skill become better at comparing any pair of texts, not only Locke and Hobbes. That transfer is the real reason to assign the essay in the first place. A well-designed rubric and thoughtful feedback make that transfer far more likely.
