Make the example prove something

The gap between evidence and commentary

The gap between evidence and commentary is where many argument essays flatten out. After the example appears, the reader still needs to know why it supports this claim and what general principle can be drawn from it. Your explanation should make the connection visible without pretending the example proves more than it does. This chapter continues with the risk-taking prompt from Chapter 30 and the Edison filament example from Chapter 31.

State what the example actually establishes

Before you write commentary, say plainly what the example demonstrates, not what a larger claim hopes it demonstrates. The Edison example shows that in one documented case, sustained team experimentation across 1,600-plus materials was part of what allowed a systematic narrowing toward a workable filament. It does not show that risk always guarantees success, that failure is more valuable than success, or that inventors are naturally more successful than other professionals.

Write the warrant the paragraph is missing

A warrant is the reasoning that connects a specific example to a general claim: the missing logical step explaining why this evidence supports this position. A paragraph that jumps from example directly to claim leaves the reader to supply the warrant.

Jump: "In 1879, Edison and his team tested more than 1,600 materials... Therefore, risk-taking is necessary for significant achievement."

A warrant fills the gap: "This case supports a narrower principle: when a goal can be reached only through uncertain experimentation, accepting the cost of failed trials can be part of the information-gathering process. It does not prove that risk is necessary for every significant achievement, or that risk by itself causes success or fame."

Weak "warrants" are really just more facts: "Edison was a famous inventor" or "The lightbulb is used in homes today" add information but supply no reasoning. A real warrant explains a mechanism: each tested material consumed time and resources, but repeated testing also narrowed the range of workable options, without which a viable filament could not be identified.

Connect the example back to the claim

After developing an example's details, tie them back to the paragraph's claim in the paragraph's own language. An example that never explicitly returns to the claim has not finished its job.

Avoid causal claims the evidence cannot carry

An example showing that one thing happened after another is not automatically evidence that the first caused the second. "Edison and his team took risks, and then Edison became famous. This proves that taking risks causes fame" treats a sequence as a cause. Fame also depended on the invention eventually working and on its historical timing. A claim the evidence can carry: "The team's willingness to risk sustained, uncertain experimentation was part of what made the eventual success possible, though risk-taking alone does not guarantee either success or recognition."

Use a second example only when it adds new reasoning

A second example earns its place when it extends or complicates the reasoning of the first. If you add a scientist who also succeeded after repeated failures, and the logic is identical to Edison's, you have added length, not argument. Better: a case where risk-taking failed to produce the goal, which complicates the first example and pushes the essay toward a more accurate claim.

Build the paragraph around one purpose

Each body paragraph should serve one purpose in the larger argument, established at its start and developed throughout. A paragraph that drifts across several unrelated points dilutes the work any one example could have done.

Make the transition show the logical relationship

A transition should signal the relationship between paragraphs: addition, contrast, or consequence. "Next, here is another example" only marks sequence. "However, risk does not always resolve so favorably, as a different kind of case demonstrates" signals contrast, which tells the reader how the reasoning is moving.

End with the argument the evidence has earned

The final sentence should state the specific conclusion the evidence and commentary built toward. "In conclusion, risk-taking is important, as this example shows" could have appeared before the example was ever introduced. Compare: "Edison's case shows that risk becomes productive specifically when repeated failure generates usable information that narrows the path toward a working solution." That sentence could only be written after the work of the paragraph.

A paragraph pattern to practice

1. Claim: one sentence with a single purpose.
2. Evidence: specific detail, as in Chapter 31.
3. What it establishes: the narrow fact the example supports.
4. Warrant: why that fact supports the claim.
5. Earned ending: a conclusion that could only follow from this evidence.
