 But if we focus for a moment on the definitions of Being and Nothing themselves, their definitions have the same content. Indeed, both are undetermined, so they have the same kind of undefined content. The only difference between them is “something merely meant” (EL-GSH Remark to §87), namely, that Being is an undefined content, taken as or meant to be presence, while Nothing is an undefined content, taken as or meant to be absence. The third concept of the logic—which is used to illustrate the speculative moment—unifies the first two moments by capturing the positive result of—or the conclusion that we can draw from—the opposition between the first two moments. The concept of Becoming is the thought of an undefined content, taken as presence (Being) and then taken as absence (Nothing), or taken as absence (Nothing) and then taken as presence (Being). To Become is to go from Being to Nothing or from Nothing to Being, or is, as Hegel puts it, “the immediate vanishing of the one in the other” (SL-M 83; cf. SL-dG 60). The contradiction between Being and Nothing thus is not a reductio ad absurdum, or does not lead to the rejection of both concepts and hence to nothingness—as Hegel had said Plato’s dialectics does (SL-M 55–6; SL-dG 34–5)—but leads to a positive result, namely, to the introduction of a new concept—the synthesis—which unifies the two, earlier, opposed concepts.
