The obvious corollary to the belief that the Bush administration is all-powerful is that the rest of us are completely powerless. --George Monbiot

The obvious error of the 9/11 deniers is in failing to falsify the claim that 9/11 was planned and executed by 19 Islamic soldiers at war with the United States and directed by Osama bin Laden. --Bob Carroll

The belief that a handful of unexplained anomalies can undermine a well-established theory lies at the heart of all conspiratorial thinking...and is easily refuted by noting that beliefs and theories are not built on single facts alone, but on a convergence of evidence from multiple lines of inquiry. All of the “evidence” for a 9/11 conspiracy falls under the rubric of this fallacy. --Michael Shermer
