The phrase 'Existence' (derived from _existere_) suggests the fact of having proceeded from something. Existence is Being which has proceeded from the ground, and been reinstated by annulling its intermediation. The Essence, as Being set aside and absorbed, originally came before us as shining or showing in self, and the categories of this reflection are identity, difference and ground. The last is the unity of identity and difference; and because it unifies them it has at the same time to distinguish itself from itself. But that which is in this way distinguished from the ground is as little mere difference, as the ground itself is abstract sameness. The ground works its own suspension: and when suspended, the result of its negation is existence. Having issued from the ground, existence contains the ground in it 'the ground does not remain, as it were, behind existence, but by its very nature supersedes itself and translates itself into existence. This is exemplified even in our ordinary mode of thinking, when we look upon the ground of a thing, not as something abstractly inward, but as itself also an existent. For example, the lightning-flash which has set a house on fire would be considered the ground of the conflagration: or the manners of a nation and the condition of its life would be regarded as the ground of its constitution. Such indeed is the ordinary aspect in which the existent world originally appears to reflection,--an indefinite crowd of things existent, which being simultaneously reflected on themselves and on one another are related reciprocally as ground and consequence. In this motley play of the world, if we may so call the sum of existents, there is nowhere a firm footing to be found: everything bears an aspect of relativity, conditioned by and conditioning something else. The reflective understanding makes it its business to elicit and trace these connexions running out in every direction; but the question touching an ultimate design is so far left unanswered, and therefore the craving of the reason after knowledge passes with the further development of the logical Idea beyond this position of mere relativity. 124.] The reflection-on-another of the existent is however inseparable from the reflection-on-self: the ground is their unity, from which existence has issued. The existent therefore includes relativity, and has on its own part its multiple interconnexions with other existents: it is reflected on itself as its ground. The existent is, when so described, a Thing. The 'thing-by-itself' (or thing in the abstract), so famous in the philosophy of Kant, shows itself here in its genesis. It is seen to be the abstract reflection-on-self, which is clung to, to the exclusion of reflection-on-other-things and of all predication of difference. The thing-by-itself therefore is the empty substratum for these predicates of relation.
