Sam Harris talks about the response to his argument at TED that “morality should be considered an undeveloped branch of science.” He discovered in the responses that “many smart people believe that something in the last few centuries of intellectual progress prevents us from making cross-cultural moral judgments — or moral judgments at all. Thousands of highly educated men and women have now written to inform me that morality is a myth, that statements about human values are without truth conditions and, therefore, nonsensical.”
