Nelson's Mandela own sense of himself was a very humble reading, [different] from how the world read him. And, quite often, you had the sense that he was not comfortable with all the accolades that would be.

One of the things that I noticed with my own eyes was Nelson Mandela ability to engage with kings and queens and heads of state on the one hand, and his ability to engage with ordinary people, equally comfortably.

Struggles only move forward when decent men and women step forward and say, 'enough is enough and no more.'

You know how they say, 'What happens in Vegas, stays in Vegas?' What happens in the Arctic doesn't stay in the Arctic.

I was 15 years old when I first heard the name Mandela, or Madiba, as he is fondly known in Africa. In apartheid South Africa he was public enemy number one. Shrouded in secrecy, myth and rumour, the media called him 'The Black Pimpernel'.

The struggle to avert catastrophic climate change is bigger than all the other struggles, whether it is slavery, democracy struggles, the woman's right to vote, and so on I would argue that if what is at stake is securing life as we know it, then there can be no bigger struggle that we face.

Many people theorize poverty, but so many elements of poverty, individually, for most people who theorize about poverty would be really difficult to even comprehend the individual things. Just take homelessness. If you are homeless, what does it mean not to have a post box where people can contact you; what does it mean not knowing where you're going to sleep at the end of the day; what does it mean not having a place where you can store what little you might possess. So dealing with homelessness in itself is a huge thing for most people who are commentators [on] or benefactors to poverty.
