Whatever the truth is about the extent to which truth is respected in the future, it is going to depend partly on what we do. More important than making predictions is doing things which help bring about this respect.

No one has ever understood anything better by assuming that there is no reason for why it is the way it is.

Perhaps the biggest myth about cynicism is that it deepens with age. I think what really happens is that experience painfully rips away layers of scales from our eyes, and so we do indeed become more cynical about many of the things we naively accepted when younger.

In the case of Donald Trump I think you've got to accept that a lot of what's going on in political discourse is based upon judgement. How the economy works - how people work - what will come to pass - what will not come to pass - what is possible - what is not possible. There is this whole modal dimension. There's a lot in politics that is making a judgement about what might be and can be and would be. Trump frightens a lot of people but there is a bizarre possible world in which it turns out as he's vindicated, though most of us think the evidence is against it.

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

There is such a thing as fanaticism, it is always wrong, and if you disagree, you're wrong too.

The optimist underestimates how difficult it is to achieve real change, believing that anything is possible and it's possible now. Only by confronting head-on the reality that all progress is going to be obstructed by vested interests and corrupted by human venality can we create realistic programmes that actually have a chance of success.
