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.

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.

The modern believer is not suspicious enough, which is perhaps why when they try to construct arguments in their defence, the convictions are left doing all the work and reason, debilitated by neglect, weakly fails to prop them up.

To a certain extent all philosophers have been involved in a systematic questioning that undermines confidence and certainty. Philosophy as a whole unleashed skeptical forces which, outside of the tightly controlled environment of a rigorous philosophical debate, led a lot of people to throw their hands up in despair and think 'what's the point?'. A lot of the public perception of philosophy is that it leaves you with no answers, and more confused than you were at the beginning.

Science works because the phenomenon being described can be relied on to remain the same. Even in quantum physics, where phenomena are changed by observation, the way in which observation interferes is regular and falls within a limited range of possibilities. Human culture, however, has the nasty habit of never staying the same for very long.

To become a stoic is to endorse the truthfulness of its world view and accept its prescription for how you ought to live, not just to like how it makes you feel.

I don't think there is ever a direct connection between the philosophical community and the wider populus. I'm very aware of this because I've been working on a book on ideas in global philosophy and you always find some kind of relation between the dominant philosophies in a culture and the folk philosophy but it's not a straight-down dissemination. It's partly bottom-up. Thinkers are the products of the cultures they grew-up in. They aspire to thinking purely objectively and universally, but they are often reflecting ways of thought that are embedded in a culture.
