logical fallacies and the art of debate   (link)

This is a guide to using logical fallacies in debate. And when I say "using," I don't mean just pointing them out when opposing debaters commit them -- I mean deliberately committing them oneself, or finding ways to transform fallacious arguments into perfectly good ones.

Debate is, fortunately or not, an exercise in persuasion, wit, and rhetoric, not just logic. In a debate format that limits each debater's speaking time, it is simply not reasonable to expect every proposition or conclusion to follow precisely and rigorously from a clear set of premises stated at the outset. Instead, debaters have to bring together various facts, insights, and values that others share or can be persuaded to accept, and then show that those ideas lead more or less plausibly to a conclusion. Logic is a useful tool in this process, but it is not the only tool -- after all, "plausibility" is a fairly subjective matter that does not follow strict logical rules. Ultimately, the judge in a debate round has to decide which side's position is more plausible in light of the arguments given -- and the judge is required to pick one of those sides, even if logic alone dictates that "we do not know" is the answer to the question at hand.

Besides, let's be honest: debate is not just about finding truth, it's also about winning. If you think a fallacious argument can slide by and persuade the judge to vote for you, you're going to make it, right? The trick is not getting caught.
