"The heart is a muscle," Bigend corrects. "You 'know' in your limbic
brain. The seat of instinct. The mammalian brain. Deeper, wider,
beyond logic. That is where advertising works, not in the upstart
cortex. What we think of as 'mind' is only a sort of jumped-up gland,
piggybacking on the reptilian brainstem and the older, mammalian mind,
but our culture tricks us into recognizing it as all of consciousness.
The mammalian spreads continent-wide beneath it, mute and muscular,
attending its ancient agenda. And makes us buy things."
