That’s why I don’t presume to predict — history is a lesson in complexity not predictability — but what I do feel I’ve learned to understand, thanks to my studies, are the mechanisms of historical change, the how of history’s dynamism rather than the what next. So, in the middle of so many discussions of the causes of this year’s events (economics, backlash, media, the not-so-sleeping dragon bigotry), and of how to respond to them (petitions, debate, fundraising, art, despair) I hope people will find it useful to zoom out with me, to talk about the causes of historical events and change in general.
