Much of 2020 felt rather binary: you’re with us or against us, you visibly support us on social media or you’re complicit, you vote my way or you’re evil. (And 2021 is looking pretty similar on that front so far.) But two books I’ve recently read argue strongly against binary thinking—when it comes to ethical decision making, we need to consider a wider array of possibilities and human complexities than just “yes” or “no.”
