One of the real dangers of our time is people's indifference to history.

I see a lot of individual action when it comes to environmental questions really as a form of politics as a way of communicating with political leaders, much in the same way that acts of civil disobedience during the civil rights' movement were really acts of political communication, trying to get laws changed rather than based on the thought that the individual action would really change the practices of segregation.

We think of history as another specialization, like philosophy of language, rather than as something that informs everything we do and think.

Climate scientists think of nothing but climate and then express their concerns in terms of constructs such as global mean surface temperature. But we live in a world in which all sorts of change is happening all the time, and the only way to understand what climate change will bring is to tell stories about how it manifests in people's lives.

I became religious and at 14 went to a boarding school 500 miles from home to begin theological studies. By the time I started university, politics had replaced religion in the economy of my enthusiasms but I had no idea what to study. My boarding school emphasized languages which I was bad at, and deemphasized math and science which I was good at.

If you look at the works psychologists have done about individual reports of wellbeing, what happens is that if you're poor, you are not happy. But once you achieve a certain level of material satisfaction then income has very little correlation with people's reported states of happiness, things like climate matter more, things like the culture of the country in which you're raised matter more and so the things really, let's face it, like individual temperament matter more than these things.

The Enlightenment is not a nightmare, nor is it something that comes easily to us. It is an aspiration - and a good one!
