Love

So listen to me when I say that love isn't something that we invented
It's... observable, powerful. It has to mean something

Love has meaning, yes
Social utility, social bonding, child rearing...

We love people who have died. Where's the social utility in that?

None

Maybe it means something more, something we can't yet understand
Maybe it's some evidence
Some artifact of a higher dimension that we can't consciously perceive
I'm drawn across the universe to someone
I haven't seen in a decade, who I know is probably dead
Love is the one thing we're capable of
perceiving that transcends dimensions of time and space
Maybe we should trust that, even if we can't understand it yet
