To the extent that we ignore this, forget about it, become complacent, or believe that it is so infinite that it can take care of itself, we are in trouble.

There was very much a real feel that we probably pretty much discovered every major fossil field in Africa. And in fact, some scientists even wrote that down at the turn of the millennia. It wasn’t a great time to be proposing to explore and push new, because we hadn’t succeeded, theoretically, being given the chance. All the big discoveries were in old sites. ... I was still an extraordinary believer in that there was more out there to be discovered. I just wasn’t demonstrating.

Well, what's very interesting is that those people read our opinions which can be, at moments, rather animated. An animated exchange in writing among the justices. And many people who read our opinions think we have to be at each other's necks constantly. It's interesting we're not. When we're talking about cases at our conference it's generally a conversation. It's really a talk about what our perspectives are and why we have reached the conclusions we've reached.

It is simplistic in the following sense that you cannot institute democracy from above. It’s a very difficult process. And democracy is not the only dimension of institutions that matters. Although my work does emphasise that democracy by itself matters as well. But the problem is really alive today in the industrialised world, where you would think, and many political scientists have claimed that democracy is safe and secure and would never be under threat. It is under threat. Support for democracy is at an all time low, not just in the US, although really jarringly in the US but not just in the US, throughout the western world. So democracy is not easy to make work because democracy is about democratic citizenship. It’s about consensus, it’s about communication. It’s about accepting defeat, making compromises, talking and understanding the other side. All of those things are always difficult. They become more difficult during times of turbulence, which, you know, we are living through and they become harder when the infrastructure, for example, the communication infrastructure, makes this sort of democratic citizenship harder, which I think is not the only factor. But social media has certainly played that role.

Of course, the most rewarding part is the "Aha" moment, the excitement of discovery and enjoyment of understanding something new, the feeling of being on top of a hill, and having a clear view. But most of the time, doing mathematics for me is like being on a long hike with no trail and no end in sight! I find discussing mathematics with colleagues of different backgrounds one of the most productive ways of making progress.
