That question is asked all the time here 🙂
Different kinds of love:
love for a lover
love for a brother or closest friend
love for a son or daughter
love just for the beauty of the world maybe.
I'm sure you mean the first 😉
But they are all emotional responses to people or things, if the last three exist then surely the first must as well. How to define them? The Greeks have different words for different kinds of 'love'. That seems sensible!
We have the capacity to think above the level of other animals. We have invented ways to examine and express our feelings subtly. So love, yes sure! But no-one said it lasts for ever, or if it does then it can re-shape itself into different forms.
Confusing and makes my head hurt!
