Time has the quality of ethics,which is mainly manifested in people's grasp of the rhythm of the movement and change of objective things,construction of natural and social order,and the carrying of human social values.The so-called time ethics refer to the values constructed by the subject based on the consideration of timeliness in the process of be-havior selection.The core concept is that the trade-off of the"present"is not only reflected in the entire time chain including"past-present-future",but also as a carrier of value,"past"and"future"provide a value"necessity"for the subject's behav-ioral choices.There is a symbiotic relationship between time and human social ethics and morality.However,due to the fact that time was regarded as absolute and as an instrument in modern times,people have overlooked the originality of time and ethics.In the process of reflecting on the values of enlightenment,it is necessary to rethink the ethical issues of time.At the same time,in the process of the great rejuvenation of the Chinese nation,it is also necessary to rethink the ethical issues of time in traditional Chinese agricultural society.
