This article inquires about this important concept in the thought system of Hegel.The authors discuss Hegel's idea about the unity of existence and consciousness, its abstract nature because of the rules governing Hegel's triads, and Hegel's arguments for existence being a primary concept. They will look into his justifications for building other concepts on this basis, as well as his divisions for existence. The way Hegel differentiates between existence and being is another issue to be discussed in this article. The authors also criticize Hegel's ideas in these regards.
