You should protest about the views of people you disagree with over major moral issues, and argue them down, but you should not try to silence them, however repugnant you find them. That is the bitter pill free speech requires us to swallow.

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.

For most people their ideal life involves an intimate relationship with another person; one which often has a sexual basis. But there's no logic about it; why shouldn't people choose to live together with someone they just like? 'Of course' if we were too unquestioning about it, and we said 'well, that person has got to be someone of the opposite sex, and it's got to be for life, and divorce is terrible', then we're stuck. But if you don't recognize the importance that kind of bond has for human beings - you can't really understand what is needed to live a good life.

When you try to translate any kind of real-life problem into a neat logical form, you're almost always simplifying it. We need a kind of blend - we need to use not just tools of logic, which are important and valuable - I'm not denying that, but also tools of judgement, and of inductive and abductive reasoning which can also inform.

It is often said that having gone through any kind of suffering tends to makes you appreciate life more and live more in the present. I'm not sure how universal or long-lasting these effects really are.

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.

People should not expect the state to protect them from fraudsters. If we do, we get into the habit of neglecting our own powers of intellectual discernment.
