Heads YOU win, Tails I lose...

Frank Beckwith illustrates the point I've been making (one, two, three, four) regarding the inconsistency any adherent to methodological naturalism has whenever they attempt to use any form of abstract thought in their arguments. In P. Z. Myers: Closet IDer? Say it Isn't So!, he says

...in order to say that ID advocates lack intellectual virtue, Myers's judgment would have to include a premise that relies on some notion of what it means for a person qua person to be intellectually virtuous. But he would, in effect, be relying on premises his materialism cannot give an account.

Well said.
