Dear shanks: You make some good points. I was just thinking of organs. I wonder what the oldtimers thought of the thymus which seems related to some words about emotions. When I was in medical school, they were just beginning to realize it had a function (immunities)
The oldtimers had some really bizarre notions. On a totally different peculiarity of the old timers, it popped into my head to wonder how many million men rubbed their hands together to warm them, before Benjamin Thompson, Count Rumford, noticed that as long as a dull drill turned in a cannon being bored, the water in the cooling bath kept boiling away. So he became famous for discovering the mechanical equivalent of heat.
And the phlogiston theory flew out the window.
