 Just as the rituals need to be based on the foundation of the Way, the ruler’s names, though they can be arbitrary as designations, must correspond to reality. You can make up the word for “reality”, but you cannot make up reality. “Same and different” (tongyi 同異) are distinguished by the so-called “Heaven-endowed bureaux” (tianguan 天官), i.e. the eyes, ears, mouth, nose, body, and heart-mind. For most of these, we might say “senses” or “sense organs” in English, but the heart-mind (xin 心) is an exceptional case, for it is said to be able to distinguish “statements, reasons, happiness, resentment, grief, joy, love, hate, and desire” (Xunzi 22.d), which are not simply sense data. The heart-mind will be treated more fully in the next section.
