Back when the the Society was trying to demonize medical organ transplants, c. 1973, they tried to establish that the heart was the source of emotion. Not in the poetic sense, but as a physical fact. (No, really, they did!)
And so the assembled masses were treated to a drama that featured on stage: a giant fibreglass brain, which flashed yellow to a canned voice-over to represent rational thought, and a giant fibreglass heart, which flashed red to a canned voice-over, representing human emotion. The conflict between these two opposing forces dealt with life-altering decision processes such as clothing purchases.
Human Actress: "It's such a pretty dress. But look how much it costs."
(Actress freezes. Conflict ensues.)
Giant Throbbing Heart: I would like to wear this dress.
Giant Throbbing Brain: You can't afford it.
Giant Throbbing Heart: But I really, really want it.
Giant Throbbing Brain: That's materialism. And you can't afford it.
Giant Throbbing Heart: But I really, really, really want it.
Giant Throbbing Brain: Showy display. And you can't afford it.
Giant Throbbing Heart: But I really, really, really, really want it.
It was one of those moments where you are embarrassed for yourself because you are watching others embarrass themselves.
