Thesis Statement Introduction Speech

Thesis and Purpose Statements

Use the guidelines below to learn the differences between thesis and purpose statements

In the first stages of writing, thesis or purpose statements are usually rough or ill-formed and are useful primarily as planning tools.

A thesis statement or purpose statement will emerge as you think and write about a topic. The statement can be restricted or clarified and eventually worked into an introduction.

As you revise your paper, try to phrase your thesis or purpose statement in a precise way so that it matches the content and organization of your paper.

Thesis statements

A thesis statement is a sentence that makes an assertion about a topic and predicts how the topic will be developed. It does not simply announce a topic: it says something about the topic.

Good: X has made a significant impact on the teenage population due to its . . .

Bad: In this paper, I will discuss X.

A thesis statement makes a promise to the reader about the scope, purpose, and direction of the paper. It summarizes the conclusions that the writer has reached about the topic.

A thesis statement is generally located near the end of the introduction. Sometimes in a long paper, the thesis will be expressed in several sentences or an entire paragraph.

A thesis statement is focused and specific enough to be proven within the boundaries of the paper. Key words (nouns and verbs) should be specific, accurate, and indicative of the range of research, thrust of the argument or analysis, and the organization of supporting information.

Purpose statements

A purpose statement announces the purpose, scope, and direction of the paper. It tells the reader what to expect in a paper and what the specific focus will be.

Common beginnings include:

"This paper examines . . .," "The aim of this paper is to . . .," and "The purpose of this essay is to . . ."

A purpose statement makes a promise to the reader about the development of the argument but does not preview the particular conclusions that the writer has drawn.

A purpose statement usually appears toward the end of the introduction. The purpose statement may be expressed in several sentences or even an entire paragraph.

A purpose statement is specific enough to satisfy the requirements of the assignment. Purpose statements are common in research papers in some academic disciplines, while in other disciplines they are considered too blunt or direct. If you are unsure about using a purpose statement, ask your instructor.

This paper will examine the ecological destruction of the Sahel preceding the drought and the causes of this disintegration of the land. The focus will be on the economic, political, and social relationships which brought about the environmental problems in the Sahel.

Sample purpose and thesis statements

The following example combines a purpose statement and a thesis statement (bold).

The goal of this paper is to examine the effects of Chile's agrarian reform on the lives of rural peasants. The nature of the topic dictates the use of both a chronological and a comparative analysis of peasant lives at various points during the reform period. . . The Chilean reform example provides evidence that land distribution is an essential component of both the improvement of peasant conditions and the development of a democratic society. More extensive and enduring reforms would likely have allowed Chile the opportunity to further expand these horizons.

The thesis statement is the center around which the rest of your paper revolves; it is a clear, concise statement of the position you will defend.

Getting Started:

If you’re just beginning to think about a thesis, it may be useful to ask yourself some of the following questions. This list is not exhaustive; anything that helps you consider your text or subject in a complex, unusual, or in-depth manner will get you on the right track:

  • Do I have a gut response to the prompt? Does anything from my reading jump to mind as something that could help me argue one way or another?
  • What is the significance of this text or subject? Why did my professor choose it? How does it fit into the broader themes or goals of the course?
  • How does this text or subject relate to the broader context of the place or time period in which it was written or in which it occurred?
  • Does this text or subject challenge or complicate my ideas about race, class, gender, or religion? About political, carceral, or educational institutions?
  • Does anything in this text seem to not “fit in” with the rest of it? Why could that be?
  • Are there aspects of the text (or two separate texts) which, when I compare and contrast them, can illuminate something about the text(s) that wasn’t clear before?
  • Does the author make any stylistic choices– perspective, word choice, pacing, setting, plot twists, poetic devices– that are crucial to our understanding of the text or subject?

Developing Your Ideas:

At this point you should have some potential ideas, but they don’t have to be pretty yet. Your next goal will be to play with them until you arrive at a single argument that fulfills as many of the above “Components of a Strong Thesis” as possible. See the following examples of weak or unfinished thesis statements:

Setting is an important aspect of Wuthering Heights.

Britain was stable between 1688 and 1783.

The first example is argumentative, but it’s not that argumentative– most critics agree that setting is important to Wuthering Heights. Both examples are too broad. One way to develop them is to consider potential conjunctions that would help you complicate your ideas:
 

See below for examples of stronger or more complete thesis statements. In part due to the addition of conjunctions “because” and “as,” these are more argumentative, more specific, and more complex:

Because the moors in Wuthering Heights are a personification of Heathcliff’s personality, their presence suggests that human emotion and the natural world are intricately entwined in the novel.

Corruption was a major source of stability in Britain between 1688 and 1783, as landed elites controlled every aspect of British government and ensured political stability at the cost of social equality.

I Have a Thesis. Now What?

Once you feel confident about your final thesis statement, you have conquered the most important (and usually, the most difficult) part of writing a paper. Here are two ways your thesis can help you figure out what to do next:

Components of a Strong ThesisComponents of a Weak Thesis
  • Argumentative, debatable
  • Specific
  • Original, goes beyond class discussion
  • Can be supported with textual evidence
  • Answers the prompt
  • Clearly and concisely stated
  • Summarizes, states a fact
  • Broad, makes a generalization
  • Repeats class discussion or other critics
  • Unrelated to or contradicted by the text
  • Unrelated or partial response to prompt
  • Language is vague, wordy

Conjunction

Conjunction’s Purpose

  • Because, so, as
  • But, however, yet, although, despite
  • When, where
  • Unless, except
  • Before, once, until
  • Specifies your reasoning
  • Introduces nuance
  • Confines idea to specific time or place
  • Introduces an exception to your idea
  • Specifies order in which things occur

 

Wuthering Heights Examples

British History
Examples

Gathering evidence: Look back at your text(s) and begin compiling a list of quotations or ideas that would support your thesis statement.

  • Descriptions of the moors
  • Descriptions of Heathcliff, or moments when other characters talk about him
  • Instances of political corruption from 1688-1783 that led to stable government
  • Instances of social inequality from 1688-1783

Considering structure: See if your thesis statement gives you any clues about how to organize your thoughts into body paragraphs.

The moors and Heathcliff can each have their own paragraph. Or separate paragraphs can tackle separate qualities, i.e. the wild nature of both, the morose nature of both, etc.

Political corruption and social inequality can each have their own paragraph. Or, if there are cause-and-effect relationships between specific instances of corruption and inequality, each pair can have its own paragraph.
