"[T]here are certain basic moral truths that all of us really know, even if we pretend to ourselves that we don't. ... [D]ifferent cultures disagree only about the details of morality, not about the basics. C. S. Lewis gave us a good example when he remarked that although some cultures say you can have four wives and some say you can have only one, up until very recently, every human culture has recognized the sacredness of marriage. ... Paul said in Romans 1 that we 'suppress' the truth because of our sins. But if the knowledge is really down there, then it can be dredged back up, no matter how deeply suppressed. ... Don't forget: People know more about right and wrong than they ever let on. And you can learn how to get past their denials in order to remind them of the moral truths that they can't not know."
