e Introduction
Simply enough, the introductory paragraph introduces the argument of your paper. A well-constructed introductory paragraph immediately captures the interest of your reader and gives appropriate background information about the paper's topic. Such a paragraph might include a brief summary of the ideas to be discussed in your paper's body as well as other information relevant to your paper's argument. The most important function of your paper's introductory paragraph, however, is to present a clear statement of your paper's argument. This sentence is your paper's thesis. Without a thesis, it is impossible for you to present an effective argument. The thesis sentence should reflect both the position that you will argue and the organizational pattern with which you will present and support your argument. A useful way to think about the construction of a thesis sentence is to view it in terms of stating both the "what" and the "how" of the paper's argument. The "what" is simply the basic argument in your paper: what exactly are you arguing? The "how" is the strategy you will use to present this argument. The following are helpful questions for you to consider when formulating a thesis sentence:
What is the argument that I am trying to convince the reader to accept?
How exactly do I expect to convince the reader that this argument is sound?
Once you have answered these questions, the next step is to synthesize these answers into a single thesis sentence, or, if necessary, two thesis sentences.
For example: You want to convince your reader that the forces of industry did not shape American foreign policy from the late 19th century through 1914, and you plan to do this by showing that there were other factors which were much more influential in shaping American foreign policy. Both of these elements can be synthesized into a thesis sentence:
Fear of foreign influence in the Western hemisphere, national pride, and contemporary popular ideas concerning both expansion and foreign peoples had significantly more influence on American foreign policy than did the voices of industrialists.
This sentence shows the position you will argue and also sets up the organizational pattern of your paper's body.
