re both Tim and Barry's comments:

Yeah, it's funny how the Greeks didn't get it right, and seems like it would
have been easy for them to inquire more thoroughly (at least, as we look
back with today's knowledge and values). But what else is interesting is how
ideas stay in the collective understanding well beyond their veracity
(assumed or proven...). For example, though we know full well exactly where
the heart and brain are and what they do, we still refer to many deeply
emotional things as "affairs of the heart" (or other phrases involving the
heart as the seat of emotions and motivation; "my heart wasn't in it,"
"heart and soul," "I love you with all my heart," etc). I guess referring to
brain structures or neurotransmitters just wouldn't cut it...

Happy New Year all,
