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

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.

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.

Trade has played a vital role in the social evolution of humankind. It allowed people to specialise, which raises both skill levels and efficiency. It brought people from different lands together, co-operating rather than competing over resources.

Rules matter, and to be rules they need to be universal in form: always do this, never do that. But it is foolish to rule out in advance the possibility that an occasion might arise when normal rules just don't apply. Rules are not there to be broken, but sometimes break them we must.

There are many things you shouldn't measure. Don't, for example, try to measure how much you love your wife!

Some of my understanding of what philosophy and ethics is has changed very slowly. One thing that has changed is this for quite a long time I bought-into the idea that philosophy is basically about arguments. I'm increasingly of the view that it isn't. The most interesting things in philosophy aren't arguments. The thing that I think is underestimated is what I call a form of attending. I think that philosophy is at least as much about carefully attending to things as it is about the structure of arguments.
