"Smith's compelling study and his argument that the study of dehumanization be made a global priority to prevent future Rwandas or Hiroshimas is well made and important." — Publishers Weekly

"Brute." "Cockroach." "Lice." "Vermin." "Dog." "Beast." People often regard other members of humankind as less than human, and use terms like these for those whom they wish to harm, enslave, or exterminate. Dehumanization has made atrocities like the Holocaust, the genocide in Rwanda, and the slave trade possible. But it isn't just a relic of the past. We still find it in war, genocide, xenophobia, and racism. Smith shows that it is a dangerous mistake to think of dehumanization as the exclusive preserve of Nazis, communists, terrorists, Jews, Palestinians, or any other monster of the moment. We are all potential dehumanizers, just as we are all potential objects of dehumanization.

Less Than Human is the first book to illuminate precisely how and why we sometimes think of others as subhuman creatures. It draws on a rich mix of history, evolutionary psychology, biology, anthropology, and philosophy to document the pervasiveness of this phenomenon, describe its forms, and explain why we so often resort to it. Less Than Human is a powerful and highly original study of the roots of human violence and bigotry, and it is as timely as it is relevant.

"Smith offers an impressively thorough survey of 'dehumanization' as it has been deployed against Jews, African Americans, and other 'Others'—as an accompaniment to exploitation and extermination." — Los Angeles Review of Books
