In the Greek language they had four (4) different words for love.
The Oxytocin type is more like the EROS type of love, sexual love.
Then there is PHILIA or brotherly love, warm love with affection or fondness for someone.
They also had STORGE which is family love, love of family.
Finally, there is AGAPE' love, or love based on principles. Emotion does Not have to be involved such as: Love (Agape) your enemies.
Love based on principle, is that really love?
I was just using love as an example. More interesting I find is the idea that feelings are a chemical process of the brain.
You love your enemies why? A feeling of moral uprightness. I was going to say moral superiority but thought it might be taken the wrong way.
