2.5 Finding a writer's thesis
A thesis is the main claim a whole text sets out to prove. Sometimes it's stated in one clear sentence, called a thesis statement; other times it's implied or spread across the text, and you have to piece it together by reading the whole thing.
Key terms
- thesis
- main claim
- explicit thesis
- implicit thesis
The thesis is the claim everything else serves
A text can contain many claims, but only one is the thesis: the overarching claim that the others support. To find it, ask what the whole text is trying to get readers to believe or do. A sentence that only explains part of the argument is a supporting claim, not the thesis.
Keep three things apart: the topic (what the text is about), the purpose (what the writer wants the text to do) and the thesis (the position the writer defends). For a speech about library fines, the topic is fines, the purpose might be to persuade a city council, and the thesis is "The library should end overdue fines." Reading questions often include a wrong answer that names the topic or the purpose instead of the claim. Titles and closing paragraphs are good places to check your guess, because writers often restate the thesis there.
Where a thesis can be
- At the start: the writer states the thesis, then spends the rest of the text proving it.
- At the end: the writer leads readers through reasons and evidence, then arrives at the thesis as a conclusion.
- Spread out: the thesis is split across two or three sentences, or stated in pieces that add up.
- Implied: the writer never states it directly, and you have to infer it from the whole text. Satire and personal essays often work this way.
Finding an implied thesis
When no single sentence does the job, build the thesis yourself.
- Sum up each paragraph in a few words.
- Ask what all of those summaries are trying to prove together.
- Write that as one sentence with a clear position.
- Test it: does every paragraph support your sentence? If one doesn't, adjust it.
Watch out for irony
In satire, the writer says one thing and means another. Jonathan Swift's A Modest Proposal (1729) seems to argue that poor Irish families should sell their babies as food for the rich. That's the surface claim, and it is meant to shock. The real thesis is the opposite: that Ireland's poor were being treated as if they were livestock, and that the people in power were ignoring practical, humane solutions. If you take a satirist's surface claim as the thesis, every answer that follows will be wrong.
Worked examples
Try each one yourself first, then open the solution.
- Example 1
An explicit thesis that previews the argument
On June 16, 1858, accepting the Illinois Republican nomination for the U.S. Senate, Abraham Lincoln said: "'A house divided against itself cannot stand.' I believe this government cannot endure permanently, half slave and half free. I do not expect the Union to be dissolved,—I do not expect the house to fall; but I do expect it will cease to be divided. It will become all one thing, or all the other." State Lincoln's thesis and explain how it points to the rest of his argument.
Show the solutionHide the solution
- Step 1: Find the main claim: the nation cannot stay permanently half slave and half free; it will become all one or all the other.
- Step 2: Notice how it's built. Lincoln opens with a familiar biblical saying his audience would accept, then applies it to the nation.
- Step 3: Notice the preview. "All one thing, or all the other" sets up two possible futures, which signals that the speech will explain which way the country is heading and why it matters.
Answer: Lincoln's thesis is that the United States cannot last permanently "half slave and half free" and will eventually become "all one thing, or all the other." Because the thesis frames the choice as two futures, it tells listeners that the rest of the speech will explain which way the country is moving and what they must do to stop slavery from spreading.
- Example 2
Inferring Swift's real thesis
Near the end of A Modest Proposal (1729), Swift's speaker says: "Therefore let no man talk to me of other expedients," and then lists the solutions he claims to reject, among them "Of taxing our absentees at five shillings a pound," and "Of teaching landlords to have at least one degree of mercy towards their tenants." What is Swift's implied thesis?
Show the solutionHide the solution
- Step 1: Recognize the irony: the speaker's proposal to eat children is monstrous, so Swift can't mean it literally.
- Step 2: Look at what the speaker brushes aside. The "other expedients" are realistic reforms: taxing landowners who live abroad and treating tenants with mercy.
- Step 3: Infer the real position: Swift wants readers to take those reforms seriously.
- Step 4: Combine the target and the solution in one sentence.
Answer: Swift's implied thesis: Ireland's poverty comes from the greed and indifference of the people with power, especially landlords who take wealth out of the country, and the practical reforms his speaker mockingly dismisses, such as taxing absentee landlords and showing tenants mercy, are exactly what Ireland needs.
Common mistakes
- Assuming the first sentence is always the thesis. Many writers build toward it.
- Stating the topic ("the essay is about slavery") instead of the claim about it.
- Taking an ironic or satirical claim at face value.
- Choosing a strong supporting claim that only explains one paragraph.
On the exam
- "Which of the following best states the main claim of the passage?" is a common reading question. The right answer fits every paragraph, not just the most memorable one.
- Getting the writer's thesis right is the foundation of a strong Question 2 essay, because you're explaining how the writer's choices serve that purpose.
