Russell Brand – Union Speaker 2014

Now in the twenty-first century we have the chance to create a better situation. Problems won’t disappear, they may increase, but adopting a peaceful approach means that we will address them by non-violent means. We need the confidence that comes from having truth on your side; it is powerful support.

Dalai Lama – Union Speaker 2013

The fact that we humans, who are ourselves mere collections of fundamental particles of nature, have been able to come this close to an understanding of the laws governing us and our universe is a great triumph.

Stephen Hawking – Union Speaker 2017

An original idea. That can't be too hard. The library must be full of them.
