As stated above, both Dawkins and Dennett aver that anyone who doubts evolution, or who does not believe it, is (let’s just list the defects they mention) “inexcusably ignorant,” “stupid,” “insane,” or “wicked” (though Dawkins is charitable enough to say he does not want to consider the latter). But then, for both of them, the case made for an unguided evolutionary process is a case based on its plausibility and not on its certainty.
