饥饿、交通事故、战争、污染、自杀是20世纪导致非正常早逝的五大耻辱。借助古典伦理可以在某种程度上减少非正常早逝，但还不足以克服现有危机。今天的生圈伦理必须重视技术进步的内容，以便确立一种新的整体化的道德。生圈伦理学源于对技术影响社会生活的批判意识。城市是历史的原动力，生圈伦理学有必要确立城市的道德领域，为城市确立其伦理基础。 Hunger, traffic accidents, wars, pollution and suicide are the five biggest causes of untimely premature death in the 20th century. With classical ethics, premature death can be reduced to some extent, but not enough to overcome the existing crisis. Today’s life circle ethics must emphasize the content of technological progress in order to establish a new holistic ethic. Living ring ethics stems from the critical awareness of the impact of technology on social life. City is the driving force of history, and it is necessary for the student circle ethics to establish the moral field of the city and establish its ethical foundation for the city.
