People seem very arrogant when they say 'I'm right and you're wrong', but in practice we all believe we're right. We have a staggering arrogance in our own belief. That can be tempered by not being 100% certain; by being provisional. No matter what the debate is, very few people have the modesty to suspend judgement on a whole range of things; most intelligent people have an opinion and are expected to have an opinion by other people - but it always requires making a personal judgement that goes way-beyond your expertise. We do it all the time.

Waiting is so unusual that many of us can't stand in a queue for 30 seconds without getting out our phones to check for messages or to Google something.

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.

True humility is expressed in deeds, not words. The humble are those who truly walk the same ground as everyone else - not necessarily with grovelling, hunched backs, but certainly not lording it over others, either.

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.

Society needs both justice and compassion, a head and a heart, if it is to be civilised.

If we now find ourselves looking down on the cheap and convenient, it is only because we now have better things which are affordable.
