Abstract: How to interpret the meaning of "good" is a longstanding challenge in moral philosophy, and the main reason is that
"good" in nature is morally normative. The purpose of speaking out a "good" statement is not only to represent the real world, but to
encourage or guide the listener to perform certain moral acts. Traditionally, scholars have either invoked another kind of normative
concept, or relied on etymological "standards/norms", or based on reasons for doing things to explain this "good" normative, but the
results are not satisfactory. This study advocates the perspective of ethical contextualism, pointing out that the meaning of "good" is
influenced by the purpose intended by moral subjects in a particular context under the premise of fixed moral values and known
information, and the normativity expressed by them is reflected in the process of moral subjects' efforts to achieve the desired purpose.
In this way, the metaphysical normative meaning of "good" can be transformed into a more concrete natural meaning
