The polarising EU referendum brought much of this to a head. Let me be clear: I do not, by any stretch, feel that people that voted to leave the EU were racist- but it's clear that UKIP, EDL, and their peers realised the power of the race card, and played it to their advantage.

It's hard for people to defend democracy when it cannot defend them against social injustice.

The printing press helped democratise Europe by providing space for discussion and agreement among politically engaged citizens, often before the state had fully democratised.

Aging is a side-effect of being a machine with moving parts. All such machines, whether living or not, inherently create entropy in their structure.

Industry and society today are one thing – it's the same business. You need to be close to humanity, have a soul, show blood. You must do the right thing, and you have to be transparent – it matters to the consumer, to the market, and to the team.

In war, you're forced to survive. It's kill or be killed, it's the most basic human instinct. You have to unleash that aggressive shadow side of yourself. It gives you a profound sense of being alive, it becomes a dopamine slot machine.

With leadership and privilege comes immense responsibility. And in this case, it basically took 20 years for the US to replace the Taliban, with the Taliban. This is a backward step of epic proportions for women's rights.
