The truth of Appearance is its Essential Relation with a supersensible world. The self-subsistent truth is that neither world can endure on its own without the other.1 Furthermore, Logic cannot determine which world is Appearance and which world is "in and for self." The predominance of one over the other is a "simply affirmative … immediacy." (512) Any such predominance is simply assigned by external reflection. Yet, since the Essential Relation represents worldly self-erasure, and since reflection is self-erasure, the relation is "a selfidentical reflection." (512)
