  This example suggests that, while people may have moral beliefs that initially few others share, free and interactive reasoning in a diverse group can reveal these moral beliefs to be the better justified among the alternatives. Many other examples, such as debates about women’’s right to education or their right to vote, convey the same message. The implication is that moral knowledge, to the extent that it is possible, is more likely to be achieved through interactive reasoning among those with diverse viewpoints who are open to criticism from each other.
