 The second moment—the “dialectical” (EL §§79, 81) or “negatively rational” (EL §79) moment—is the moment of instability. In this moment, a one-sidedness or restrictedness (EL Remark to §81) in the determination from the moment of understanding comes to the fore, and the determination that was fixed in the first moment passes into its opposite (EL §81). Hegel describes this process as a process of “self-sublation” (EL §81). The English verb “to sublate” translates Hegel’s technical use of the German verb aufheben, which is a crucial concept in his dialectical method. Hegel says that aufheben has a doubled meaning: it means both to cancel (or negate) and to preserve at the same time (PhG §113; SL-M 107; SL-dG 81–2; cf. EL the Addition to §95). The moment of understanding sublates itself because its own character or nature—its one-sidedness or restrictedness—destabilizes its definition and leads it to pass into its opposite. The dialectical moment thus involves a process of self-sublation, or a process in which the determination from the moment of understanding sublates itself, or both cancels and preserves itself, as it pushes on to or passes into its opposite.
