“ To say nothing of the fact that Holbach speaks of mental phenomena being produced by material conditions as of a self-evident proposition, nothing could be more awkward than the mode in which he strives to wrest the weapon from the hand of his opponent. By adopting the comparison of the molecules of matter with cogged dice, he unwittingly admits that in nature, just as in a gambler's den, there is trickery; whereas the problem before him was to explain how material particles not directed toward any definite end should nevertheless cooperate to that end. ”
