In my political essays I often write "David Brooks also suggests that love can bridge gaps and provide a unifying force.

What big idea counteracts division, fragmentation, alienation? It is found in Leviticus and Matthew: Love your neighbor. Today’s left and right are fueled by anger and seek conflict. The big idea for moderates should be solidarity, fraternity, conversation across difference. A moderate agenda should magnify our affections for one another."

So yes, love can change the world.
