 The world “substance” is clearly ambiguous. One translates it through the notion of self-sufficiency, i.e., the possibility of existing without a ground, but also as the possibility of existing without inhering [in something else]. (Ak. 28:1308; Ak. 8:225n, 28:562, 28:779, 28:638–9, 28:1041, 28:1104f)
