A conference titled "The Evolution of Morality: The Biology and Philosophy of Human Conscience" will be held in the idyllic location of Erice, Sicily, on June 17-22 2012. The speakers will be a highly interdisciplinary group of evolutionary biologists, ethologists, neuroscientists, anthropologists, psychologists, philosophers, and theologians, who speak a common theoretical language in addition to their disciplinary training. David Sloan Wilson speaks with the famed primatologist Frans DeWaal, one of the organizers, about the conference and what it means to approach the topic of morality from an evolutionary perspective.
