 Other technical, syntactic terms include aufheben (“to sublate”), which we already saw  (section 1),  and “abstract”. To say that a concept or form is “abstract” is to say that it is only a partial definition. Hegel describes the moment of understanding, for instance, as abstract (EL §§79, 80) because it is a one-sided or restricted definition or determination  (section 1).  Conversely, a concept or form is “concrete” in the most basic sense when it has a content or definition that it gets from being built out of other concepts or forms. As we saw  (section 2),  Hegel regarded Becoming as the first concrete concept in the logic.
