When one looks for these terms in his writings, one finds so many occurrences that it may become clear that Hegel employed the Kantian using a different terminology.

Hegel explained his change of terminology. The triad terms, 'abstract-negative-concrete' contain an implicit explanation for the flaws in Kant's terms. The first term, 'thesis,' deserves its anti-thesis simply because it is too abstract. The third term, 'synthesis,' has completed the triad, making it concrete and no longer abstract, by absorbing the negative.

Sometimes Hegel used the terms, immediate-mediate-concrete, to describe his triads. The most abstract concepts are those that present themselves to our consciousness immediately. For example, the notion of Pure Being for Hegel was the most abstract concept of all. The negative of this infinite abstraction would require an entire Encyclopedia, building category by category, dialectically, until it culminated in the category of Absolute Mind or Spirit (since the German word, 'Geist', can mean either 'Mind' or 'Spirit').
