This book is being written within an unprecedented historical moment. However, that would be true no matter when it was written. I’m typing this sentence during a global pandemic, but I’d probably consider the current historical moment unprecedented even if COVID-19 had never come into existence. Every time period that’s ever transpired has seemed unprecedented to the people who happened to live through it; no one has ever believed the Chinese aphorism “May you live in interesting times” did not apply to the life they were coincidentally living.
