“Trump and Zuckerberg, though they probably agree on nothing, are the two blades of a pair of scissors that is cutting the fabric of truth to ribbons,” writes the philosopher and activist Bernard-Henri Lévy in his most recent book, The Empire and the Five Kings. Widely regarded as France’s most prominent intellectual, Lévy co-founded the New Philosophers School and has published several books. But he started his career as a war correspondent, and continues to uphold the truth—as gruesome as it may be—by making documentaries. Screenings of four of Lévy’s films—on the Bosnian War (Bosna!, 1994), war-torn Libya (The Oath of Tobruk, 2012), and jihadi fundamentalism (Peshmerga, 2016, and The Battle of Mosul, 2017)—celebrate his important work. —J.V.
