This edition includes a modern introduction and a list of suggested further reading. Although dubbed “Darwin’s bulldog,” Thomas Huxley did not think the doctrine of evolution could give us a sense of ethics. He felt an evolutionary account of our origins must take morality quite seriously, and we must build it into our theories about human behavior. Even today, the attempt to build a naturalistic ethics grounded in evolutionary theory remains problematic, and Huxley’s writings are as relevant as when he first penned them.
