Aristotle's Rhetoric

I would like my class presentation to be on Aristotle's Rhetoric as discussed in The Rhetorical Tradition by Patricia Bizzell and Bruce Herzberg. On page 171, Aristotle's rhetorical theory is described as follows: "Scholars agree that the starting point is Aristotle's division of rhetoric into two major categories: "artistic" proofs, for which the rhetorician constructs the material (e.g., "My client is too good to have committed this crime"), and "inartistic" proofs, for which the rhetorician interprets existing evidence (e.g., "These three witnesses place my client elsewhere at the time the crime was committed"). Traditionally, Aristotle has been read as dividing artistic proofs into appeals to logos, pathos, and ethos." The authors go on to describe the "nonartistic proofs" as references appeals to physical evidence (p. 174). My science 'persona' would lean towards nonartistic proofs, yet, my rhetorical (and artistic) 'persona' would rely more on the artistic proofs. I look forward to uncovering the descriptions, definitions and strategies that Aristotle introduced in his Rhetoric work.
