Ethics in the modern context is under the dual pressure of scientific-technological rationality and market commercialization, which has led to breakthroughs in the original boundaries of knowledge and academic methodology. The gradual separation of the domain of public life and that of private life in modern society and the former’s increasing pressure on the latter, in addition to the above dual pressure on ethics, is causing a dramatic transformation of the structure of ethical knowledge itself. All of these raise new theoretical problems for ethics and ethicists in the modern context. Answering and solving these problems makes sense for the future development of ethics as one of the classic humanities, and tests modern ethicists’ ability to realize their moral and theoretical duties.
