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.

If there's one thing that makes me cynical, it's optimists. They are just far too cynical about cynicism. If only they could see that cynics can be happy, constructive, even fun to hang out with, they might learn a thing or two.

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.

Most people believe, more or less, that the value of a human life is the same, irrespective of where on the planet it happens to find itself. But, of course, not every life has the same value for us.

Indeed, without emotion it seems unlikely we can even have morality.

The very act of questioning whether you exist proves you do, because you must be there for the doubt to be entertained in the first place.

In my experience, those who make the biggest fuss about not spending much at Christmas are generally the ones who buy what they want and eat where they want 12 months a year.
