During the twentieth century we saw consumption boom beyond the planets natural limits, beyond what the planet is capable of sustaining. Everything is connected, forest destruction is a major cause of global warming, climate change.

We have the ability to push much further than we think is possible, but the brain wants us to rest to allow the body to recover. With practice and training we can overcome almost any discomfort.

When you examine how these myriad factors intertwine, from genetics and evolution to the proteins synthesized mere minutes ago, you see a continuous arc. In my view, there's no room in this intricate web for free will.

People who are building don't want to simply test their ideas in a microcosm, they want to be successful in the real-world, and San Francisco is an international city with real world connections.

Every reason why we fight reveals a cost that our society ignored. The grisly, terrible costs of fighting are often 'nil' where, for example in the case of a dictator, the leadership is not held to account.

We can become resilient however, and learn to have peace of mind, even when we experience traumatic events. We can learn to have stable peace of mind... happiness? Maybe not. It's unhelpful to say to someone, 'do these 10 things to be happy' – there are things you can do to get peace of mind, increase your probability of happiness, and your probability of having successful relationships.

Robert Edwards won the 2010 Nobel Prize for IVF. By then, millions of children had been born through it. On the very day his Nobel was announced, the Vatican said giving him the prize was 'completely out of order'. Same person, same achievement, same day -- celebrated as a saviour by some, condemned as a murderer by others. That is what a real moral controversy looks like. It doesn't dissolve, even after the technology has changed millions of lives.

Fundamentally, we must slow-down the process of change. We should recognise that most change is not progress- and therefore, it is in our interests to slow down without interfering too much with actual solution making.

We estimate that between 2010 and 2015, there will be 150million new Chinese entering the middle-class. That's a middle-class which increasingly buys diamonds as a gift of love and as a memento of stature.

Upon arriving in Germany, swimming became my sanctuary during a time when I had no other home. Being new to the country and unfamiliar with its swimming culture, the sport offered me solace and a sense of belonging. It provided a common language that allowed me to connect with others effortlessly, facilitating a smoother integration into German society.

The people who influence the best are the ones who take the advice of the ancient Chinese military expert, Sun Tzu. Every battle is won before it's fought. If you put people in a mindset that is congruent with the major focus of the message you are yet to send them, it opens the door to persuasion.

The first one is to believe in the 'otherisation'. The otherisation states that anybody who is looking at the world through their lens is on one group, and everybody outside of this world view is another. And they are different and separate.
