We have lived through an era where success has been defined only in financial terms- leaving out any consideration of the impact of business on communities or the world. Just because accounting standards don't require you to measure certain things, doesn't mean those things aren't real.

Slowly, over the course of a decade, we built relationships by proving we weren't there to destroy luxury's heritage and its 'unspoken codes of conduct,' but actually to protect them and enable this industry to thrive. We were fashion insiders, and we just happened to be coders too!

The idea that if you are proud to be British you need to be proud of British history is nonsensical. Does it mean you have to be proud of all of history? Of slavery? You might as well be proud of biology or jelly.

They tend to have quite a power of persuasion and dominance in person. That gets diminished when they are reduced to words on a page.

The question I always ask them is '…what has our foreign policy got to do with Muslims travelling thousands of miles to go and kill other Muslims in Iraq and Syria?'

The team was a meritocracy in which performance alone was rewarded. As I got better and my team started winning championships for my school, my status as freakishly tall black kid became a badge of accomplishment and inclusion.

Inventors shouldn't be afraid to take risks. They should embrace failure and learn from their mistakes. I created 5,127 prototypes of the first Dyson bag-less vacuum cleaner and only the last one was right! Not being afraid to fail is something I think all successful entrepreneurs have in common.

Science can purify religion from error and superstition. Religion can purify science from idolatry and false absolutes.

Revolution was, in a way, the original problem of political thought. Constitutionalism is a Greek answer to the problem of revolution. You want to avoid revolution? Then you need to design a constitution in a certain way—so that it's balanced and less likely to be overturned by revolution.

We need to change our hearts and minds, not just our behaviours. Forget even the moral argument, discriminating is such a waste. It is from our diverse cultures and communities that we could find the cure for cancer, where we could find all of the solutions for some of our most pressing problems.
