McLuhan's Brain

"Marshall McLuhan’s brain was fueled by fresh blood from the heart through not one but two arteries at the base of his skull, a trait in the mammalian world found mostly in cats and rarely in human beings ... Why mention this medical information? To establish that Marshall was not merely different but very different, and it wasn’t simply in the way he thought; rather, it was because of the biological mechanisms that made and allowed him to think what he thought."
