Science is more than a body of knowledge. It’s a way of thinking: a way of skeptically interrogating the universe.
We are like butterflies who flutter for a day and think it is forever.

The politicians and the religious leaders and the weapons scientists have been at it for a long time and they’ve made a thorough mess of it. I mean, we’re in deep trouble.
When permitted to listen to alternative opinions and engage in substantive debate, people have been known to change their minds. It can happen.
