Perpetrators of violence, we’re told, dehumanize their victims. The truth is worse.

A recent episode of the dystopian television series “Black Mirror” begins with a soldier hunting down and killing hideous humanoids called roaches. It’s a standard science-fiction scenario, man against monster, but there’s a twist: it turns out that the soldier and his cohort have brain implants that make them see the faces and bodies of their targets as monstrous, to hear their pleas for mercy as noxious squeaks. When our hero’s implant fails, he discovers that he isn’t a brave defender of the human race—he’s a murderer of innocent people, part of a campaign to exterminate members of a despised group akin to the Jews of Europe in the nineteen-forties.

The philosopher David Livingstone Smith, commenting on this episode on social media, wondered whether its writer had read his book “Less Than Human: Why We Demean, Enslave, and Exterminate Others” (St. Martin’s). It’s a thoughtful and exhaustive exploration of human cruelty, and the episode perfectly captures its core idea: that acts such as genocide happen when one fails to appreciate the humanity of others.

One focus of Smith’s book is the attitudes of slave owners; the seventeenth-century missionary Morgan Godwyn observed that they believed the Negroes, “though in their Figure they carry some resemblances of Manhood, yet are indeed no Men” but, rather, “Creatures destitute of Souls, to be ranked among Brute Beasts, and treated accordingly.” Then there’s the Holocaust. Like many Jews my age, I was raised with stories of gas chambers, gruesome medical experiments, and mass graves—an evil that was explained as arising from the Nazis’ failure to see their victims as human. In the words of the psychologist Herbert C. Kelman, “The inhibitions against murdering fellow human beings are generally so strong that the victims must be deprived of their human status if systematic killing is to proceed in a smooth and orderly fashion.” The Nazis used bureaucratic euphemisms such as “transfer” and “selection” to sanitize different forms of murder.
