One of the most quoted ideas in The Fault in Our Stars is the notion that some infinities are bigger than other infinities. Hazel and Augustus use it to think about whether a short life can be a complete one. That question makes an excellent prompt for an argumentative essay, because students can take a position and support it with evidence from the novel and their own reasoning. It also demands careful grading, since philosophical claims are easy to make and hard to prove.

A good prompt frames the idea as a question that the novel can be used to answer. Students might argue whether Green ultimately presents a short life as meaningful, or whether the novel leaves room for doubt. They can support their claim with the conversation about infinities, the events in Amsterdam, and Hazel's closing reflections. Requiring evidence from multiple parts of the book keeps the argument from resting on one famous line.

Philosophical writing brings its own risks. Students may make sweeping claims about life and death that sound profound but say little. Teachers can guard against this by requiring a definition of key terms, such as what "meaningful" or "complete" means in the essay. A clear definition forces the student to commit to an idea that can be tested against the text.

Building Strong Arguments From Abstract Ideas

Strong essays connect abstract ideas to concrete moments. A student who argues that a short life can be full might point to Hazel and Augustus's shared experiences, the way they choose to spend their limited time, and how they leave an impact on the people around them. Each piece of evidence supports a specific part of the claim. This structure keeps the essay grounded and gives the reader something to evaluate.

• A defined position on whether a short life can be complete or meaningful
• Definitions for the key abstract terms the argument depends on
• Concrete scenes that illustrate each part of the claim
• A counterargument that takes seriously the loss the characters experience
• A conclusion that explains what the argument reveals about the novel as a whole

Feedback on Reasoning and Logic

Feedback on philosophical essays should attend to the logic of the argument. Does each paragraph follow from the last, and does the evidence actually support the claim it is attached to? A comment such as "how does this scene show that the life was complete rather than simply happy?" pushes the student to refine their reasoning. Pointing out logical gaps is more useful than correcting phrasing.

Students also benefit from feedback on how they handle counterarguments. A thoughtful opponent might say that grief and loss make a short life tragic regardless of how meaningful it was. An essay that engages that view seriously will be more persuasive than one that ignores it. Teachers can reward this engagement explicitly in the rubric.

Scoring Fairly When Opinions Differ

Because the topic touches on deeply personal beliefs, teachers must take care not to reward agreement with their own views. The rubric should focus on the quality of reasoning, use of evidence, and engagement with alternatives. Anchor papers that take opposite positions but both score well can demonstrate that the assessment is about argument, not conclusion. This clarity encourages students to write honestly.

AI-assisted grading tools can help maintain fairness by applying the rubric to every essay in the same way. They can also identify essays that lack definitions or evidence, allowing the teacher to focus comments where they are needed. The teacher reviews all results and adjusts as necessary, particularly for essays with unusual but defensible approaches. Together, these practices support both consistency and intellectual openness.
