 Thesis 10 presents an ethical principle tied together with an ontological one, which presumably is meant to justify it. Since everything can be summed into a whole—the Great One—heaven and earth and the myriad things contained therein can be considered a single “body” or  “unit.”[12]  (In classical texts, the expression ‘heaven and earth’ refers to the cosmos, including not only the sky and earth but the entire natural world.) The ethical principle follows intuitively. If everything is one unit, then any care (ai, also “love”) we have for ourselves should also be directed at all of the other myriad things (wu, “things,” or, perhaps more specifically, “creatures”), since fundamentally we are all parts of the same vast “unit” or “body.” This ethical stance takes the ideal of impartiality even farther than the Mohists. Their position is that we must care inclusively for every person in the world. Thesis 10 advocates caring for every thing as well.
