The following dialogue is taken from the movie "Interstellar". Highly recommended.
"You’re a scientist, Brand -"
"I am. So listen to me when I tell you that love isn’t something we invented - it’s observable, powerful. Why shouldn’t it mean something?"
"It means social utility - child rearing, social bonding -"
"We love people who’ve died ... where’s the social utility in that? Maybe it means more - something we can’t understand, yet. Maybe it’s some evidence, some artifact of higher dimensions that we can’t consciously perceive. I’m drawn across the universe to someone I haven’t seen for 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 yet understand it."
Yes, but love takes effort. And it takes effort because like light, love is made of myriads of tiny particles; kindness, generosity, understanding, selflessness, care... This is the secret that allows it to transcend space and time. Every one of these characteristics is about overcoming, transcending, breaking through the barriers of everyday life, normality, expectation. Beyond gaining, beyond life itself in some cases.
"Do not go gentle into that good night; Old age should burn and rave at close of day. Rage, rage against the dying of the light."
The sky is roaring tonight. So am I.
