ABSTRACT
Excellent, good, right, or correct moral norms are the moral norms that conform to the moral value of behavior, while inferior, bad, wrong or incorrect moral norms are the moral norms that do not conform to the moral values of behavior. Therefore, although moral norms are made by human, only inferior, bad, wrong, or incorrect moral norms are arbitrary. Conversely, excellent, good, right, or correct moral norms are deduced and made from the moral value of the behavioral ought (namely the utility of “behavioral fact” to the goal of morality), which, in the final analysis, can be deduced from behavioral facts through the goal of morality. Therefore, the excellence or inferiority of moral norms of the behavioral ought, depends directly on the truth or falsehood of the judgment of moral value of the behavioral ought, and fundamentally, depends on both the truth or falsehood of the judgment of the goal of morality and the truth or falsehood of the factual judgment of behavior. This is the “deductive postulate of excellent moral norms in ethics” which can deduce all propositions in ethics, and can be summed up as the formula below:
Premise 1: the behavioral fact (substance of moral value).
Premise 2: the ultimate goal of morality (standard of moral value).
Conclusion 1: the behavioral ought (moral value).
Conclusion 2: the moral norm is good or bad (whether the moral norm is consistent with moral value).
