David Corn on Christopher Hitchens:
"When he did address the issue of the absent WMDs in Iraq, he took a strange turn. 'Doesn't anything ever strike you as odd," he said, "about the figure of zero for [WMD] deposits found in Iraq? ... Isn't it odd that none after all this? None? Doesn't that suggest a crime scene that has been pretty well dusted in advance, the fingerprints wiped? Well, it does to me.' Read that quote carefully. It is revealing. Hitchens was saying that the fact that no weapons had been uncovered in Iraq (after nearly three years of searching) was evidence that there had been weapons. How can one argue with a person of such intellectual prowess that he can turn absence into presence by mere deduction?Ooooh, there's a great critical thinking example for arguing from ignorance.
