In a sense, then, an argument is another word for a thesis. An argument needs to be narrow enough for you to defend in the length of essay assigned. You need to be able to find enough evidence to support your assertions. You need to make a point worth arguing: a point that elicits a "so what?" from your reader will not generate a strong essay.
The "so what" question is a good test for your argument. If you pursue your argument, why is it important? What will readers learn from it? How will it illuminate a text or help us to answer a problem? The "so what" question can help you to distinguish a summary of observations from a real argument. For example, you may notice that in a certain short story there are recurring images of light and dark. This observation strikes you as interesting: why? What question do you want to ask about this imagery? What inferences can you draw from this imagery? When you notice something interesting in a text, you are on your way to asking a question, and that question puts you on your way to formulating an argument.
Argument essays begin with good questions. Often, those questions are generated by primary texts. You notice something surprising, disturbing, or interesting in the text, and you formulate a question to help you understand why. Sometimes your questions come from your dissatisfaction with the interpretations offered in secondary sources. You think: although expert A offers one interpretation, I would like to offer another. Your interpretation, supported by the evidence that you think is relevant, becomes your argument.
Sometimes your questions come from problems that emerge from class discussions, but are not fully resolved. You think: we have gone so far in discussing a poem, but I think additional interpretations can be made. Those interpretations become your argument.
No matter what position you may take to answer your question, your argument essay will contain four basic elements:
Sometimes, the existence of counter-arguments makes students feel uncomfortable: how, they ask, can they put forth an argument that anyone else has opposed? Here is some advice to consider when dealing with opposing arguments:
Testing the strength of your argument:
Do you interpret the quotation? Do not assume that your reader
will draw the same conclusions from the quotation that you have
drawn. Quotations should not substitute for your own explanations.
Quotations are evidence for your own assertions.
