To live with integrity, it is important to know what's right and what's wrong, to be educated morally. However, merely KNOWING is not enough. Virtuous character matters more than moral knowledge. The reason is simple: like the self-confessing apostle Paul in Romans 7, most of those who do wrong know what's right but find themselves irresistibly attracted to its opposite. Faith idles when character shrivels
If anthropological data suggests something short of the ideal, that is not because nothing is universal, but because two universals are in conflict: universal moral knowledge and universal desire to evade it. The first one we owe to our creation. The second we owe to our fall.
