We do wrong willfully when we fail to think hard about whether what we're doing is right.

I maintain the importance of an absolute prohibition against torture, while acknowledging that even absolute prohibitions can sometimes be broken. If that is a contradiction, it is a contradiction that ethics has to embrace, or else it becomes like glass: hard, clear, but fatally inflexible.

The mark of a mature, psychologically healthy mind is indeed the ability to live with uncertainty and ambiguity, but only as much as there really is. Uncertainty is no virtue when the facts are clear, and ambiguity is mere obfuscation when more precise terms are applicable.

I don't believe in God because certain reasons and arguments weigh more heavily in my mind than others, not because I have willfully decided to reject my creator, as many religious people seem to think. I could no more simply decide to believe in God than I could decide to like beetroot, just like that.

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

The greatest moral failing is to condemn something as a moral failing: no vice is worse than being judgmental.

True respect means taking other people's beliefs seriously and assuming they are adult and intelligent enough to be able to cope with it if you tell them, clearly and civility, why you think they are totally, utterly and disastrously wrong.
