[the impact of the internet on liberty and free speech has been] very positive indeed – not so much two steps forward and one step back, as ten steps forward for every step back. By breaking the oligopoly of the established press and letting everyone be a publisher, it has made information much harder for the powerful to control.

Sometimes, rappers' lyrics really do offer gripping tales of loss, sorrow, exploitation, rage, confinement, hopelessness, and despair about conditions that are denied in the larger society.

I think it was recognising that revolution was, in a way, the original problem of political thought. But in fact, constitutionalism is a Greek answer to the problem of revolution. You want to avoid revolution? Then you need to design a constitution in a certain way—so that it's balanced and less likely to be overturned by revolution.

We have reason to be optimistic, but until the public get angry enough about homelessness with politicians rather than the homeless, nothing will change. Politicians respond to public opinions that they believe are electorally significant.

Power is relational; we talk about seizing power but ultimately – at least in democratic societies – you need the followers to be powerful, and it's important therefore for us to understand the cognitive biases that mean that we keep gravitating towards people who are clearly unfit for the job.

There's a lot of synergy between music and entrepreneurship. There's that kind of similar taking risks, that innovation. I think it's a really exciting time.

People who learn fast and who have some level of 'natural' talent may go home from practice early because they don't have to work as hard as others to get to their target level of achievement, but when you study super-achievers, you find that instead of going home early, they work late, and really pull-away from the crowd.

I often hear people say that everything that matters must be measured, and if it can't be measured, it doesn't matter. I believe the absolute reverse. Nothing that matters can be measured. I don't think there's anything on this earth worth lifting a finger for that you can measure.

We have learned that the things that matter are not the physical, and material things. What matters in life is hope. Tomorrow is not a given, and we must be happy about small things and we must seize the day.

The general theory that integration is good for better allocation of resources is not the big thing, the big thing is that it makes it harder for governments to play with financial markets.

People like Trump rally people behind them by pointing out threats; these may be real, but most likely are imaginary or inflated. Then he says, 'only I can protect you.'

There is a big black box of as-yet unimagined risk. Most of what now seem like the biggest risks to society were unknown one hundred years ago.
