Happiness is not the same as life satisfaction, while neither are identical to what we might call flourishing.

I think that a lot of social movements, political movements, powerful ones - certainly they form, collectively, an idea of the truth which becomes hard to question. It becomes a dogma, and from the inside it starts to look like common sense.

Being a good neighbour is about compassion, which is as warm-blooded as justice is cool-headed.

Anger clearly has its proper place at work, which is neither wholly absent nor ever present. The manager who is an emotional blank is just as hard to work for as the volcanic boss, and both can do great harm by setting an unhelpful example for what kind of emotional expression is expected and accepted.

Progress is more of a challenge for the cynic but also more important and urgent, since for the optimist things aren't that bad and are bound to get better anyway.

I just think that the skepticism about truth has almost completely flipped - from being something associated with generally left-leaning progressives to being something which is a tool of right-wing populists and demagogues. I think a lot of those people writing books ten years ago would now think those books are no longer needed, they've kind of been vindicated.

Once Steve Fuller said that there is this idea that your responsibility as an intellectual is just to speak the truth as you see it. But actually, you should be more appreciative of what needs to be said. I don't think that's ever an excuse to say something you don't believe is true - but sometimes the emphasis has to be different. Well, if I'm talking to an audience of hardline atheists, I'll be trying to unsettle them a bit more, whereas, if I'm speaking to an audience of believers, I'll be giving them more of the pros of atheism. It's about having a sensitivity to context.
