Bernard Williams on the Human Prejudice

In “The Human Prejudice”, Bernard Williams discusses our treating human beings differently in our moral thinking from the ways we treat other creatures. He criticises the idea that this expresses a prejudice, speciesism, analogous to racism and sexism. His essay has been misunderstood by some of its critics, including Peter Singer and Jeff McMahan. My essay sets out several questions one may have about Williams's essay, and explains how they can be answered. I make clear the connections between “The Human Prejudice” and some main elements in Williams's thinking about ethics, including his criticisms of moral theory.
