9.LEARNING HOW TO USE LOGOS IN RHESTORIC STYLE

Finally, a writer appeals to readers through the appeal to the readers' sense of logos. This is commonly called the logical appeal, and you can use two different types of logic. You can use inductive logic by giving your readers a bunch of similar examples and then drawing from them a general proposition. This logic is pretty simple given this, that, and the other thing-poof, there you go, a conclusion. Or, you can use the deductive enthymeme by giving your readers a few general propositions and then drawing from them a specific truth. Like, "because such-'n-such is true and such-'n-such is true and such-'n-such is true and everybody agrees on this other thing, then-poof, stands to reason, a new truth.

Since the time that a bunch of guys called "The Royal Society" (Hume, Locke, Bacon, etc.) rejected deduction, our culture has generally favored induction because it's often called the "scientific method" and we like science. Historically, people have also attributed feminine metaphors to deductive logic and then easily dismissed it or dismissed the general propositions as "not documented" or "old wives tales."
