Civilization does not have to perish. The brutes are winning only by default.
Have you ever felt a potential love for someone? Like, you don't actually love them and you know you don't, but you know you could. You realise that you could easily fall in love with them. It's almost like the bud of a flower, ready to blossom but it's just not quite there yet. And you like them a lot, you really do. You think about them often, but you don't love them. You could, though. You know you could.
