If you're interested in winning, you will destroy your opponents' arguments. But if you're interested in the truth, you will fix their arguments for them to the best of your ability, and then set out to update your position accordingly.<p>To make an impression on <i>me</i>, don't go looking for easily dismantled arguments. Pick your most formidable intellectual opponents. Try arguing successfully against the best available brand of "denialism" (what a word!) - the blog Climate Audit. For example, explain to me this: <a href="http://www.climateaudit.org/?p=5902" rel="nofollow">http://www.climateaudit.org/?p=5902</a> .
