First, the defense normally points out how much information there is, and how little persuasive content there is, but it ignores the fact that there is nothing wrong in persuasive speech. Persuasive speech is as old and reputable as factual, informative speech. It occupies, in fact, a far larger domain in everyday conduct. A good two thirds of speech that goes on is of a persuasive character. Most politicians' speech is persuasive.
Most artistic speech is persuasive.
Much religious speech is persuasive. You are then in good or bad company, if you're in the business of persuasive speech. And the rhetorical devices that advertisers use are essentially of the same sort as used by politicians, religious leaders and artists. They were ennobled both by Greek commentators and Roman commentators talking about different sorts of speech. So advertisers shouldn't pretend that advertising should be like scientific reports.
