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"

摘要： 内容提要 行为之应该如何的道德价值,说到底,不过是行为之事实如何对于道德最终目的——保障社会存在发展和增进每个人利益——的相符抑或违背之效用,因而是通过道德最终目的,亦即道德终极标准,从行为事实如何中产生和推导出来的:符合道德最终目的的行为之事实,就是行为之应该,就是具有正道德价值的行为;违背道德最终目的的行为之事实,就是行为之不应该,就是具有负道德价值的行为。这就是可以推演出伦理学的全部内容、全部对象的伦理学公理。我们可以将其归结为一个道德价值推导公式:前提1:道德最终目的(道德价值主体)前提2:行为事实如何 (道德价值实体)结 论1:行为应该如何(道德价值)结论2:与行为道德价值相符的优良道德(优良道德规范)
