 We can also use the textbook Being-Nothing-Becoming example to illustrate Hegel’s concept of aufheben (to sublate), which, as we saw, means to cancel (or negate) and to preserve at the same time. Hegel says that the concept of Becoming sublates the concepts of Being and Nothing (SL-M 105; SL-dG 80). Becoming cancels or negates Being and Nothing because it is a new concept that replaces the earlier concepts; but it also preserves Being and Nothing because it relies on those earlier concepts for its own definition. Indeed, it is the first concrete concept in the logic. Unlike Being and Nothing, which had no definition or determination as concepts themselves and so were merely abstract (SL-M 82–3; SL-dG 59–60; cf. EL Addition to §88), Becoming is a “determinate unity in which there is both Being and Nothing” (SL-M 105; cf. SL-dG 80). Becoming succeeds in having a definition or determination because it is defined by, or piggy-backs on, the concepts of Being and Nothing.
