Siris is all over the latest of PZ Myers’ increasingly empty critiques of philosophical positions he dislikes. Worth quoting:

There was a time when he was a fairly sharp commentator, and would never have made the amateurish and in some cases, frankly, dimwitted maneuvers that he makes here. But reason is in great measure social, and that means it is heavily influenced by the company one keeps; and any look at the Pharyngula comment boxes or some of the places on the web Myers links shows exactly what the quality of company he has been keeping is. And, very noticeably, his arguments have increasingly taken on some of the worst features of the glib and mindless people with whom he is constantly interacting: the tendency to begin not with the actual arguments but with a simplistic caricature of them; the attempt to build an argument not on the basis of relevant examples but on the basis of vague, incantatory rhetoric; the tendency to assume that if his opponents argue for a qualification of some claim that they are arguing for the complete falsehood of that claim; the increasing framing of every particular point as an either/or between his preferred view and irrationality; the sneering at positions in ways that show clearly that no effort was actually made to understand the position in the first place; the appeals, which were always a weakness of Myers’s and have only become more common, to pseudo-history rather than actual historical evidence; the increasingly common failure to consider that if he doesn’t understand an argument that it might be better to raise an elucidating objection than to dismiss the argument out of hand. The list could be made much longer.
