科技伦理需要实现四大转向，即伦理转向、生活转向、时代转向与中国转向，否则将有违科技伦理的宗旨和使命。伦理转向是针对科技伦理的去伦理化现象而言的，目的是确认伦理是科技活动的底色，伦理属性是科技伦理的根本属性；生活转向是针对科技伦理的理论化现象而言的，目的是回归伦理学的生活本体，并确认科技伦理的实践伦理属性；时代转向是针对科技伦理的架空式研究而言的，目的是确认科技伦理的时代主题以及其作为伦理学的当代形态的角色；中国转向是针对科技伦理的西方化倾向而言的，目的是促进中国科技伦理自主知识体系的建立。在四大转向中，伦理转向是前提，生活转向是基础，时代转向是关键，中国转向是落脚点。

According to the purpose and mission of the ethics of science and technology, it is necessary for the ethics of science and technology to achieve the following four pivotal turns: the ethical turn, the life-oriented turn, the era-responsive turn, and the China-focused turn. To overcome the ignorance of ethical dimension in the ethics of science and technology, the ethical turn emphasizes that ethics is the underlying tone of scientific and technological activities and ethical attributes constitutes the fundamental characteristics of the ethics of science and technology. The life-oriented turn tackles the over-theorization of the ethics of science and technology, aiming to revert to life as the foundation of the ethics of science and technology and affirm its practical essence. The era-responsive turn counters the detached research approach in the ethics of science and technology, seeking to identify the contemporary themes of the ethics of science and technology and establish its role as a contemporary form of ethics. The China-focused turn addresses the westernization tendency of the ethics of science and technology, aiming to foster the establishment of an independent knowledge system for China’s ethics of science and technology. Among these four turns, the ethical turn serves as the premise, the life-oriented turn as the foundation, the era-responsive turn as the key, and the China-focused turn as the ultimate objective.
