ncMEXr60AeILest one think Barron a metaphysical nut, his notion of the devil closely resembles the social media concept of the 'meme', a word coined by Richard Dawkins' in the 1976 book The Selfish Gene. It is "a unit of cultural transmission, or a unit of imitation and replication ... [like] melodies, fashions and learned skills [that] generally replicate through exposure to humans, who have evolved as efficient copiers of information and behavior.
Memes are information objects that are in some sense alive, able to morph and become sufficiently viral to take over a host and produce copies of itself from its resources. Just as melodies can reproduce so can perversion. Such a thing would act like Barron's demon, turning "seminaries into 'cesspits'" or converting ancient universities into foundries of civilizational destruction as the case may be. This property was so powerful thirty years after Dawkins published his book he thought it might better have been titled The Immortal Gene.
