Abstract:

Moral nihilism, as a kind of profound moral philosophy, issues the greatest challenge to other moral doctrines since it seeks to strip off various moral masks and present the real aspect of life. So far this is concerned, moral nihilism plays a part of antidote in the moral realm. However, its destructive role of morality cannot be neglected. If its spread is let alone, the social community will be in a danger of disintegration or disruption. In order to overcome the huge impact of such a theory, Plato contrives varied countermeasures deliberately in his Republic. So far, they still can be regarded as the best response to moral nihilism.

Key words: moral nihilism, Plato
