 Thesis 9 is another of those involving indexicals, in this case “center,” and is also very obscure. The thesis claims that the center of the world is north of the northernmost state and south of the southernmost. Possibly the thesis is a variant of thesis 3, that the sky is as low as the earth. The point there was that from the perspective of the infinitely vast whole, the difference between the height of the sky and earth may be insignificant. Thesis 9 could be making the analogous point that the distance between Yan and Yue is insignificant. Another possibility is that if space is infinitely large, then every standpoint can count as the center (Graham 1989: 79, after the 3rd-century Sima Biao). Possibly this thesis is a variant of the same idea as the third thesis in the Xunzi list, which was that the far west and far east are “adjacent.”
