中文摘要：

从道德哲学视域对谎言问题进行刨根究底式的辩证拷问,弄清其存在的正当性根据及其必要性边界,不仅有利于拓展对谎言、道德性谎言和诚实德性等基本道德问题的理解,而且对深化道德教育应该保持必要张力的思考也具有十分重要的启发。即当代道德教育需要保持道德理论与道德实践之间的张力,保持道德理念、道德要求与道德行为之间的张力,保持积极的道德与消极的道德之间的张力。

英文摘要：

Investigating lies dialectically and thoroughly from the perspective of moral philosophy,clarifying the legitimacy and necessity boundary of the existence of lies,is not only conducive to broadening the understanding of the basic moral issues such as lies,morale lies and honest virtue,but also has very important inspiration on deepening contemporary moral education. Namely,it needs to keep the necessary tension between ethical theory and moral practice,moral requirements and ethical behavior,positive morality and negative morality.
