The author and CNN host Fareed Zakaria calls the coronavirus pandemic “the most transformative event of our lifetimes.” He says: “What has happened over the last 50 years is, we have gotten increasingly confident about the power of science and medicine, so we’ve kind of lost sight of the effect that something like a plague, a pandemic, has. And I think this was a mistake."The historian Margaret MacMillan visits the podcast to discuss her most recent book, “War: How Conflict Shaped Us,” one of the Book Review’s 10 Best Books of 2020. MacMillan has written about specific wars in the past, but here she looks more broadly at the subject throughout human history, which led her to some new conclusions. “What I hadn’t really got involved in or really understood,” MacMillan says, “was the debate about whether war is something that’s biologically driven — are we condemned to war because of something that evolution has left us with, or is war the product of culture?”Also on this week’s episode, Gregory Cowles and John Williams talk about what they’re reading. Pamela Paul is the host.
