Thesis Statements and Topic Sentences
A thesis statement defines the scope and purpose of the paper. It needs to meet three criteria:
1. It must be arguable rather than a statement of fact. It should also say something original about the topic.
Bad thesis: Lily Bart experiences the constraints of many social conventions in The House of Mirth. [Of course she does. What does she do with these social conventions, and how does she respond to them? What's your argument about this idea?]
Better thesis: Lily Bart seeks to escape from the social conventions of her class in The House of Mirth, but her competing desires for a place in Selden's "republic of the spirit" and in the social world of New York cause her to gamble away her chances for a place in either world. [You could then mention the specific scenes that you will discuss.]
2. It must be limited enough so that the paper develops in some depth.
Bad thesis: Lily Bart and Clare Kendry are alike in some ways, but different in many others. [What ways?]
Better thesis: Lily Bart and Clare Kendry share a desire to "pass" in their respective social worlds, but their need to take risks and to reject those worlds leads to their destruction.
3. It must be unified so that the paper does not stray from the topic.
Bad thesis: Lily Bart gambles with her future, and Lawrence Selden is only a spectator rather than a hero of The House of Mirth. [Note: This is really the beginning of two different thesis statements.]
Better thesis: In The House of Mirth, Lawrence Selden is a spectator who prefers to watch and judge Lily than to help her. By failing to assist her on three separate occasions, he is revealed as less a hero of the novel than as the man responsible for Lily's downfall. [Note: Sometimes thesis statements are more than one sentence long.]
4. Statements such as "In this essay I will discuss " or "I will compare two stories in this paper" or "I was interested in Marji's relationship with God, so I thought I would talk about it in this essay" are not thesis statements and are unnecessary, since mentioning the stories in the introduction already tells the reader this.
Good topic sentences can improve an essay's readability and organization. They usually meet the following criteria:
1. First sentence. A topic sentence is usually the first sentence of the paragraph, not the last sentence of the previous paragraph.
2. Link to thesis. Topic sentences use keywords or phrases from the thesis to indicate which part of the thesis will be discussed.
3. Introduce the subject of the paragraph. They tell the reader what concept will be discussed and provide an introduction to the paragraph.
4. Link to the previous paragraph. They link the subject of the present paragraph to that of the previous paragraph.
5. Indicate the progression of the essay. Topic sentences may also signal to the reader where the essay has been and where it is headed through signposting words such as "first," "second," or "finally."
Good topic sentences typically DON'T begin with the following.
1. A quotation from a critic or from the piece of fiction you're discussing. The topic sentence should relate to your points and tell the reader what the subject of the paragraph will be. Beginning the paragraph with someone else's words doesn't allow you to provide this information for the reader.
2. A piece of information that tells the reader something more about the plot of the story. When you're writing about a piece of literature, it's easy to fall into the habit of telling the plot of the story and then adding a sentence of analysis, but such an approach leaves the reader wondering what the point of the paragraph is supposed to be; it also doesn't leave you sufficient room to analyze the story fully. These "narrative" topic sentences don't provide enough information about your analysis and the points you're making.
Weak "narrative" topic sentence: Lily Bart next travels to Bellomont, where she meets Lawrence Selden again.
Stronger "topic-based" topic sentence: A second example of Lily's gambling on her marriage chances occurs at Bellomont, where she ignores Percy Gryce in favor of Selden. [Note that this tells your reader that it's the second paragraph in a series of paragraph relating to the thesis, which in this case would be a thesis related to Lily's gambling on her marriage chances.]
3. A sentence that explains your response or reaction to the work, or that describes why you're talking about a particular part of it, rather than why the paragraph is important to your analysis.
Weak "reaction" topic sentence: I felt that Lily should have known that Bertha Dorset was her enemy.
Stronger "topic-based" topic sentence: Bertha Dorset is first established as Lily's antagonist in the train scene, when she interrupts Lily's conversation with Percy Gryce and reveals that Lily smokes.

Tips for Writing Your Thesis Statement
1. Determine what kind of paper you are writing:
- An analytical paper breaks down an issue or an idea into its component parts, evaluates the issue or idea, and presents this breakdown and evaluation to the audience.
- An expository (explanatory) paper explains something to the audience.
- An argumentative paper makes a claim about a topic and justifies this claim with specific evidence. The claim could be an opinion, a policy proposal, an evaluation, a cause-and-effect statement, or an interpretation. The goal of the argumentative paper is to convince the audience that the claim is true based on the evidence provided.
If you are writing a text that does not fall under these three categories (e.g., a narrative), a thesis statement somewhere in the first paragraph could still be helpful to your reader.
2. Your thesis statement should be specific—it should cover only what you will discuss in your paper and should be supported with specific evidence.
3. The thesis statement usually appears at the end of the first paragraph of a paper.
4. Your topic may change as you write, so you may need to revise your thesis statement to reflect exactly what you have discussed in the paper.
Thesis Statement Examples
Example of an analytical thesis statement:
An analysis of the college admission process reveals one challenge facing counselors: accepting students with high test scores or students with strong extracurricular backgrounds.
The paper that follows should:
- Explain the analysis of the college admission process
- Explain the challenge facing admissions counselors
Example of an expository (explanatory) thesis statement:
The life of the typical college student is characterized by time spent studying, attending class, and socializing with peers.
The paper that follows should:
- Explain how students spend their time studying, attending class, and socializing with peers
Example of an argumentative thesis statement:
High school graduates should be required to take a year off to pursue community service projects before entering college in order to increase their maturity and global awareness.
The paper that follows should:
- Present an argument and give evidence to support the claim that students should pursue community projects before entering college
