Principle 01
Extension 推己及人
Use yourself as the measuring instrument. Whatever you yourself do not desire, do not impose on others. This is not a commandment but an algorithm: input is your own felt experience, output is how to treat everyone else. Moral knowledge is always already available — you only need to run the projection.
Principle 02
Rectification of Names 正名
Language is infrastructure. When a title — father, ruler, minister — no longer matches the behavior it names, cooperation collapses not from malice but from semantic drift. 「名不正,则言不顺;言不顺,则事不成。」Fix the name first; conduct corrects itself.
Principle 03
The Mean 中庸
「过犹不及」— going beyond the mark is the same as falling short. The mean is not a compromise midpoint but the exact right point relative to each situation — a moving target, and the hardest one to hit. Courage overshoots into recklessness; generosity overshoots into waste. Precision is the virtue.
Principle 04
Learning × Reflection 学思并重
「学而不思则罔,思而不学则殆」— input without processing is bewilderment; processing without input is peril. The two must run as a coupled loop: study supplies the material, thought digests it into judgment. Neither alone produces knowledge.
