Literary argumentation at the advanced level requires a thesis that does more than identify a topic. A defensible thesis expresses an interpretation that requires defense through evidence and a line of reasoning. It may preview the logical development of the argument without simply listing devices or evidence. A line of reasoning is the logical sequence of claims that work together to support the thesis; it is communicated through commentary that explains the relationship between evidence and claim. Evidence is chosen strategically to illustrate, clarify, exemplify, associate, amplify, or qualify a point. Evidence is sufficient when its quantity and quality provide apt support for the line of reasoning. More sophisticated arguments may address alternative interpretations, discuss the broader significance of the reading, or use analogies to clarify the interpretation. Attribution of words and ideas from the text is required; on timed exam essays, a formal citation style like MLA is not required, but the source of quoted or paraphrased material must be clear.
Draft a thesis for a poem you have read. Then ask: does this claim require defense? Does it preview a logical sequence of ideas? Can you identify at least two pieces of evidence that support different steps in that sequence?
