Ethics is a science that studies moral phenomena, that is, the origin, essence, function and development law of morality.
1. Normative ethics has always been the representative, subject or core of ethics. It cares about the standard of moral right and wrong, clarifies the principles, norms and categories of morality, explores the historical inevitability of the emergence, development and change of moral norms, demonstrates the structure and function of the moral norms system, and holds that morality must rely on various norms to adjust the relationship between people in order to control people's desires.
Medical ethics is the concrete application of normative ethics in medical practice, that is, a discipline formed by analyzing and solving moral problems between medical practice and medical science development by using the theory of general normative ethics, which belongs to applied normative ethics.
Therefore, ethics and medical ethics are dialectical unity, including medical ethics, which is a part of ethics and the relationship between generality and individuality, universality and particularity.
