Character, ritual, and relationships › Reciprocity requires imagination and correction

In 15.24, Zigong asks for a word that can guide a lifetime of practice. The answer invokes shu, commonly translated as reciprocity, and tells him to refrain from imposing on others what he would reject for himself. The principle tests the easy exception one makes for one's own convenience: a burden does not become acceptable merely because another person must carry it.

This is not an instruction to exchange identical favors or reward only those who reciprocate. Its immediate form places a restraint on the agent's treatment of others. Nor is it a complete decision procedure. If I enjoy blunt public criticism, applying my preference to someone else may still humiliate them. The principle needs an account of what matters about their position, rather than a projection of my tastes.

A defender can respond by distinguishing a starting point from a conclusion. My dislike of being dismissed gives me an initial reason to consider another person's vulnerability to dismissal. I must then listen to learn how that vulnerability appears in their circumstances. On this interpretation, reciprocity prompts an inquiry; it does not allow me to answer on someone else's behalf. This reply strengthens the principle, but it adds interpretive work that its brief formulation does not spell out.

A third hypothetical case makes the stakes concrete. A team is introducing an automated system that ranks applicants. Its designer would resent being rejected by a process that offered no explanation or chance to correct an error. Reciprocity gives her a reason to examine whether applicants receive meaningful notice and recourse. It does not prove that every ranking system is wrong or determine a technically adequate appeal process. Those judgments require information and standards beyond this passage.

The point of the example is to widen responsibility. A person can behave courteously in direct conversation while imposing unexplained burdens through an institution. Applying reciprocity to the design of a process asks whose difficulties remain invisible from the designer's position. This is a contemporary extension of the text's ethical question, not a claim that Confucius anticipated automated decision systems.
