Comparing Hobbes and Locke is one of the most common essay assignments in political philosophy courses, appearing in AP Government, AP European History, and college-level intro courses alike, precisely because the two philosophers share a starting point (the state of nature and the social contract) while reaching sharply different conclusions about legitimate government. Grading these essays well requires more than checking whether a student accurately describes each philosopher individually. A genuinely comparative essay has to show how the two theories interact, where they agree, where they diverge, and why those divergences matter, which is a distinct skill from simply writing two accurate summaries side by side.

The most common structural weakness in these essays is what teachers sometimes call the "split essay" problem, where a student writes several accurate paragraphs about Hobbes, then several accurate paragraphs about Locke, without ever putting the two arguments in direct conversation with each other. Each half might earn a high score on its own, but the essay as a whole fails the comparative task the prompt actually assigned. A rubric needs a dedicated category for genuine comparison, not just accuracy, that specifically rewards sentences where a student explicitly connects a claim about Hobbes to a claim about Locke within the same paragraph.

A well-built comparative rubric should also account for the fact that students often default to the most famous point of disagreement between the two philosophers, absolute versus limited sovereignty, while ignoring subtler and arguably more interesting differences, such as their differing accounts of property, consent, or the right to revolution. Rewarding depth over breadth matters here: an essay that develops one well-chosen point of comparison in real detail should outscore an essay that lists five surface-level differences without explaining any of them. This distinction should be built explicitly into the rubric's top-scoring band description.

Designing the Comparison Category

The comparison category itself needs precise language to be gradeable consistently across a stack of essays. Rather than a vague descriptor like "compares the two philosophers effectively," a stronger rubric row specifies what comparison actually looks like in a sentence, for example requiring that a top-scoring essay use explicit comparative language ("unlike Hobbes, Locke argues...") rather than simply placing two claims near each other and letting the reader infer the connection. This level of specificity makes the rubric usable not just by the teacher but by students revising their own drafts before submission.

• Explicit comparison: does the essay use direct comparative language rather than placing separate summaries side by side
• Balanced treatment: does the essay give roughly proportional attention to both philosophers rather than favoring one
• Point selection: does the essay choose a meaningful, well-developed point of comparison rather than a superficial list
• Textual grounding: are claims about each philosopher supported with accurate evidence from their respective texts
• Synthesis: does the conclusion draw a genuine insight from the comparison rather than simply restating both positions

Common Scoring Disputes and How to Prevent Them

Comparative essays generate more grade disputes than single-author essays, largely because students can reasonably disagree about which points of comparison matter most, and a rubric that is too rigid about which specific differences must appear can penalize a legitimately strong, differently structured argument. The fix is not to abandon specificity but to grade the comparison category based on execution quality rather than topic selection, rewarding any well-developed, accurately supported comparative claim rather than requiring a fixed list of required points. This keeps the rubric fair to genuinely different but equally strong essays while still preventing the vague, surface-level comparisons that weaker essays tend to produce.

It also helps to clarify, before grading begins, how much weight the rubric gives to comparing the philosophers' methods versus their conclusions, since students often default to conclusions (absolute versus limited government) while overlooking meaningful differences in how each philosopher argues toward those conclusions. A rubric that explicitly rewards attention to argumentative method, not just outcome, tends to produce more sophisticated student writing over the course of a semester, since it signals to students that the how of an argument matters as much as the what.

Feedback That Improves the Next Comparative Essay

Because comparative writing is a transferable skill that students will use again on essays about other philosopher pairs, feedback on a Hobbes-Locke essay should be framed in terms that generalize rather than terms specific only to these two thinkers. A comment like "you summarized both positions accurately but never connected them" teaches a skill the student can apply the next time they write a comparative essay, on any pair of authors, while a comment focused only on factual accuracy does not transfer in the same way. Framing feedback around the comparative skill itself, not just the content, gets more long-term value out of the grading process.

Teachers grading a full set of these essays at once also benefit from tracking which specific comparative move students are collectively struggling with, whether that is connecting arguments explicitly, choosing a substantive point of comparison, or synthesizing a genuine insight in the conclusion. Noticing a pattern across many papers, rather than treating each essay as an isolated case, makes it possible to address the gap directly in the next class session rather than repeating the same individual correction dozens of times across separate sets of comments. A comparative rubric designed with this kind of pattern-tracking in mind pays off well beyond a single assignment.
