在绝对道德价值上,道德代价具有负面的价值,而在相对道德价值上,道德代价又有一定的正面价值。道德代价的正面价值主要体现为三个方面:道德代价是道德进步和社会进步的一个前提条件;道德代价是道德进步和社会进步的一个必然环节;道德代价是道德进步和社会进步的一种推动力量。 In the absolute moral value, the moral cost has negative value, while in the relative moral value, the moral value has certain positive value. The positive value of morality is mainly reflected in three aspects: the moral cost is a prerequisite for moral progress and social progress; the moral cost is an inevitable link between moral progress and social progress; the moral cost is a kind of promotion of moral progress and social progress power.
