Abstract: The moral value of a right act is nothing but a unity of the act's fact with the final end of morality, which aims at social development and the growth of everyone's benefit,so it is inferred from the final end of morality or the final moral standards.If the fact of a right act is in unity with the final end of morality,then it is an act that ought to be done.If it is not in unity with the final end of morality,then it is not an act that ought to be done. Then we can get an ethical axiom,which comes out through the following formula:Premise Ⅰ: the final end of morality(the subject of moral value)Premise Ⅱ: the fact of a right act(the entity of moral value)Conclusion Ⅰ: how an act ought to be done(moral value)Conclusion Ⅱ: good morality in unity with moral value(good moral norms)

Key words: good morality, moral norms and moral value, "to be"and "ought"
