Abstract
At the core of Hegelian ontology are pure nothing and pure
being, as well as the instant becoming between them, which were
established through the quest for the beginning of philosophy in
his famous book Science of Logic. However, for the past two centuries,
that process of ontological construction by Hegel was not carefully
examined by scholars all over the world. By delving into some details of
Hegel’s discourse in his Science of Logic, this paper would identify one
critical logical defect in the process of that construction, which would
determine that the Hegelian logic would not be a rigorously
self-consistent logic system without presupposition as Hegel claimed.
