To the Editor:
As a professional philosopher, I found myself with no worries about whether Marc Hauser’s theory would put my colleagues in ethics out of business. There’s a tremendous difference between the two questions: 1) Why do human beings make the judgments of right and wrong that they do?; and 2) Are these judgments correct?
Perhaps an evolutionary story can suffice to answer the first question, but I can’t imagine how it might answer the second.
