 The fourth group deal with temporal relations. Thesis 4 is paradoxical but easily intelligible. Just as from one perspective the sun is at its highest, from another perspective it is beginning to set. Just as things are living and growing, they are also coming closer to death. Again, the plurality of perspectives threatens to collapse the distinction between two apparent opposites, living and dying. In comparison with thesis 4, thesis 7 is extremely obscure. Clearly, it attempts to collapse the difference between today and yesterday or present and past. Interestingly, this paradox combines spatial and temporal relations, since in addition to the distinction between today and yesterday, there is the spatial movement from here to Yue (a state in the south). Hence Harbsmeier (298) and Graham (79) both propose to interpret the paradox in terms of the infinite divisibility of space and time, suggesting that if I cross the border into Yue precisely at the instant when today turns into tomorrow, the result is that I am simultaneously leaving one state today and arriving in the other tomorrow. Another possibility is to point out that xi, the word rendered “yesterday,” is also commonly used to mean simply “the past” or “previously.” So thesis 7 can be restated, “Today I go to Yue, but I arrive in the past.” The import of the paradox could be that all “arriving” is always in the past: whenever we arrive somewhere, our journey is completed, or “past.”
