Psychology

I knew I could still fight, and some of the people close to me said, 'not with one eye you can't' so I continued anyway... I lied, I cheated and scammed the system... I did whatever I could. It was highly stressful, but I believed in myself.

You're not going to be a warrior in battle unless you are a warrior in preparation. You have to be single-minded, you can't just show-up on the night... That's where the warrior mindset turns on – it's when you prepare so can do whatever it takes to win that fight.

When you're getting defeated in training, you're getting better. You've got to get tested in life if you're going to improve. When you're training in the martial arts, you always want to be getting beaten in the practice room. That signifies you're fighting good people.

It's ironic. You would assume that when you go in to compete in a sport like mixed martial arts, you'd want to wind yourself up, get angry, get mad, and get fired up... When you're angry, you're in a frantic state of mind, you are not the best version of yourself. When you're fighting the very best martial artists on the planet, you cannot react out of emotion. You have to be cool, calm, collected and in the moment.

There's an innate tendency in human-beings to sort ourselves by how much we want power. Some of us don't want it at all, some of us are absolutely obsessed with it. The interaction between the individual and the system is therefore critical.

Political scientist & author specializing in authoritarianism and democracy

Our brains are adapted to pick leaders based on characteristics that are no longer adaptive, or necessary today. In times of crisis for example, we are wired to gravitate towards strong men – strong males who are overconfident and speak of solutions in simplistic terms. That's what historically it took to survive.

Our senses are the conduit between the external world and our interior. When we're born, we have some wiring, but essentially a very limited experience of the exterior. To really understand the world we inhabit, we need to try and observe it. In order to function in the world, we need to have a model of the world upon which we base predictions.

We seem to be in a strange period of history where our official world view, our official picture of the universe denies the reality of the thing that's most evident and the thing that gives life value. I think people do feel this at an intuitive level, and it can lead to a deep sense of alienation, a sense that we don't fit into the world somehow.

Philosopher specializing in consciousness and panpsychism

The first thing I'd say is a big mistake is not caring about what the other side wants. Oftentimes people are thinking I have to say no to the other side. My goal is to say yes to them. It's to figure out what it is they want and give it to them.

I think people all the time, hide or lie about information that would be useful to share. If you think about somebody who's selling their business because they want to climb the seven summits and they think, Oh… that's sort of embarrassing, it's selfish ….and so they say, I'm doing it because I'm retiring. We hide things that are ultimately good reasons.

We have angels in mythology which fly everywhere, we have fairies, we have myths like the Greek myth of Icarus. It does have a great hold over our imagination. I feel it's such a wonderful thing to be able to leave the tyranny of gravity to leave the ground and fly wherever you will.

Evolutionary Biologist & Author of "The Selfish Gene

Magical thinking is a bi-product of cognitive process that were useful in our evolutionary survival. We're so good at pattern matching that we see patterns everywhere, even when they don't exist. It's better to believe the movement in the dark is a tiger, rather than the wind blowing thru a bush. Its better to be wrong on that, than the other way around.

We have to be aware of our cognitive fallacies to build some immunity to our cognitive traps. One simple thing we can all do is work on our own confirmation bias from time to time. I try to read things by people I disagree with for example, because I want to hear their best arguments and see whether my beliefs and values stand-up to them.

We are a product of evolution, and the mechanism of evolution is natural selection. Evolution is selecting for survival, and the qualities we have are evolved to help us survive as well as possible. Our cognitive capability to reason has not evolved to find truth, it evolved to help us survive and that means that we sometimes find it easier to stay with a group rather than believe the correct thing.

When you're involved in conflict, you're not sane. You may start out being sane, and in those early stages it's certainly possible to mediate and arbitrate. Using those tools you often end up cutting the baby in half – you give a little, I give a little, you give a little more, I give a little more, and suddenly everyone is miserable.

Without music, life would be hollow. Music is like food, we need it. It's essential. It's invisible, and doesn't require our attention, and so it gets threaded into our lives. Music becomes a strong part of our memories, our sense of self, and identity.
