Given an abstract definition of a being "A" and a concept "B". Can a being "A" be defined or described in terms of a concept "B", if it was "A" who gave rise to "B" ? In other words, can "B" be used to prove something about "A".
Note: Here, by "gave rise to" I mean "created" (or "makes it exist" if you prefer) and not just "discovered".
My question is meant to be general, but here is a possible instantiation of "A" and "B" if it helps to better understand the question: an instance of "A" is "God", and an instance of "B" is "Existence". So for instance, can the question "Does God exist ?" even be asked, if "God" created the concept of "Existence" ?
