Very well, I feel this topic has elements like a coin with 2 distinct sides. Like you said, according to science, the heart is just an organ that pumps blood and the brain is the seat of intelligence - ideas, decisions etc.
On the other hand, the heart is symbolic to emotions. While the brain is still the normal reasoning faculty. So from the "Independence" - I love and have read that book more than I can count😁 - Tayo followed a normal and natural reasonable thing to do... Marrying whom he impregnated but emotionally, the affair has no much true love there... I bet only sexual feelings.
All in all, both the brain and the heart should be utilized hand in hand to produce results. But I feel for majority of issues in this world needn't emotions!!
I rest my case! 🚶
hmmm.well analysed
