Abstract: In the recent 20 years,moral degeneration has been a hot topic for argument.We hold that it is not appropriate to say that moral degeneration is the order of the day.For instance,in the field of political morality,there has been much progress.However,it is also true that public morality is getting ever worse,without the light of which,we cannot explain the current wide-spread corrupted phenomena.Today,the urgent job is not to describe and appraise the situation of moral crisis,but to find out the origin of civilization abnormality and moral corruption and seek an effective moral remedy.And it is in this point that the previous ethics,owing to its own thoretical black hole or blind spot,failed to give a solution,and the moral construction which advocated traditional virtues ended in faliure,which accelerated the situation of immorality.Therefore,to patch up the “black hole” and get out of the “blind spot”,and seek a reasonable way for the construction of public morality is the impending task of present-day ethics.

Key words: civilization abnormality, moral corruption, absense of constant virtue
