The purpose of this essay is to examine the significances of guilt in moral education. At first, the traditional moral psychology has a concern for the virtue education. But, in the 1960's, an autonomist approach is brought to the fore. In recent years, as many moral psychologists criticize such a cognitive developmental approach, a virtue-centered approach comes to life again. Especially, a shame and guilt seem to get the limelight of moral psychology and moral education. The guilt has both positive and negative consequences. Teachers must not forget that guilt is one of moral driving force.
