You Talking to Me? The Art of Persuasion from Aristotle to Obama
A witty and well-written introduction to the classical theory of rhetoric, with examples and explanations. The glossary of rhetorical terms is particularly useful.
I don't think You Talking to Me will be of enormous practical use to most readers. It's hard to envision sitting around listening to political sound bites and thinking "By Jove! That was a jolly fine zeugma!"
It is, however, an enjoyable way of analyzing and describing how a persuasive argument should work. As usual, the people who would most benefit from reading it are the people least likely to do so; we seem, indeed, to have largely given up on the idea of "persuasion" as a part of public discourse, in favor of mere bombast--the sort of thing that's meant to sound good in short bites, so that the people who already agree with you will have something to agree with you on.
American readers should be warned that You Talking to Me? has a substantial quotient of British cultural references, some of which are quite obscure.
Anyone interested in this topic should run out and buy Gary Wills's Lincoln at Gettysburg, if you haven't read it already.
