A duff attitude toward evidence

"The problem with flat-earthers, creationists, homeopaths, and the rest is not so much that they have a duff conception of truth as that they have duff attitudes toward evidence."

- Simon Blackburn, Truth's Caper ($), The New Republic, Aug. 13, 2008, p. 40, at 43 (reviewing Beyond the Hoax: Science, Philosphy and Culture, by Alan Sokal).
