The bad news is that the nearest book is really a tome: Classical Rhetoric for the Modern Student by Edward Corbett and Robert Connors. I am reading it to prepare to teach a high-school grammar and composition class in the fall. Here's my selection:
"In summary then, let us say that when we are engaged in any kind of deliberative discourse, we are seeking to convince someone to adopt a certain course of action because it is conducive to happiness or to reject a certain course of action because it will lead to unhappiness. The two main special topics under the general head of happiness are the worthy and the advantageous. In developing these special topics, we will sometimes have occasion to use some of the common topics, such as the possible and the impossible (when urging the advantage for instance, of a certain course of action, we may have to show that the course we are advocating is practicable or easy) and the topic of more and less (when seeking to direct a choice from among a number of goods, for instance, we have need of criteria to help us discriminate degrees of good)."
Long sentences, no? Here's who I'm going to tag (don't know how to do live links yet): DuraMater and Little Red House. I read some other blogs, but I don't know them well enough to feel like I can tag them *blush.* But hey, I tried to participate, which is a big step for me!
